RESUMO

Three new phenols (1-3), one new cyclohexanol (4), two known phenols (5-6), and six known flavonoids (7-12) were isolated from the n-butanol of the 75% ethanol extract of all plants of Chimaphila japonica Miq. Among them, compound 5 was named and described in its entirety for the first time, and compounds 9 and 10 were reported in C. japonica for the first time. The structures of all compounds were confirmed using a comprehensive analysis of 1D and 2D NMR and HRESIMS data. Biological results show that compounds 4, 7, and 11 exhibited potent diuretic activity. The modes of interaction between the selected compounds and the target diuretic-related WNK1 kinase were investigated in a preliminary molecular docking study. These results provided insight into the chemodiversity and potential diuretic activities of metabolites in C. japonica.

RESUMO

PURPOSE OF REVIEW: Fluid retention or congestion is a major cause of symptoms, poor quality of life, and adverse outcome in patients with heart failure (HF). Despite advances in disease-modifying therapy, the mainstay of treatment for congestion-loop diuretics-has remained largely unchanged for 50 years. In these two articles (part I: loop diuretics and part II: combination therapy), we will review the history of diuretic treatment and current trial evidence for different diuretic strategies and explore potential future directions of research. RECENT FINDINGS: We will assess recent trials, including DOSE, TRANSFORM, ADVOR, CLOROTIC, OSPREY-AHF, and PUSH-AHF, and assess how these may influence current practice and future research. There are few data on which to base diuretic therapy in clinical practice. The most robust evidence is for high-dose loop diuretic treatment over low-dose treatment for patients admitted to hospital with HF, yet this is not reflected in guidelines. There is an urgent need for more and better research on different diuretic strategies in patients with HF.

RESUMO

BACKGROUND: Hydrochlorothiazide, a diuretic commonly used for the treatment of hypertension, is often associated with serious metabolic side effects. Pyrrosia petiolosa (Christ) Ching is a traditional Chinese medicine that possesses diuretic properties, without any obvious side effects. AIM: To evaluate the diuretic effect of P. petiolosa (Christ) Ching and to elucidate its underlying mechanism of action. METHODS: Extracts obtained from different polar components of P. petiolosa (Christ) Ching were analyzed for toxicity in a Kunming mouse model. The diuretic effects of the extracts were compared to that of hydrochlorothiazide in rats. In addition, compound isolation procedures, cell assays of Na-Cl cotransporter inhibition and rat diuretic test of monomeric compounds were conducted to identify the active ingredients in the extract. Subsequently, homology modeling and molecular docking were performed to explain the reason behind the diuretic activity observed. Finally, LC-MS analysis was used to elucidate the underlying mechanism of action of P. petiolosa (Christ) Ching. RESULTS: No toxicity was observed in mice administered P. petiolosa (Christ) Ching extracts. The ethyl acetate fraction showed the most significant diuretic effect. Similar results were obtained during the analysis for Na+ content in rat urine. Further separation of P. petiolosa (Christ) Ching components led to the isolation of methyl chlorogenate, 2',3'-dihydroxy propyl pentadecanoate, and ß-carotene. Results from cell assays showed that the Na-Cl cotransporter inhibitory activity of methyl chlorogenate was greater than that of hydrochlorothiazide. This result was again confirmed by the diuresis tests of monomeric compounds in rats. The molecular simulations explain the stronger interactions between the methyl chlorogenate and Na-Cl cotransporter. Of the compounds determined using LC-MS analysis, 185 were identified to be mostly organic acids. CONCLUSIONS: P. petiolosa possesses significant diuretic activities without any obvious toxicity, with least two possible mechanisms of action. Further study on this herb is warranted.

RESUMO

Background: Leptadenia pyrotechnica Forssk. Decne is a member of family Apocynaceae and locally known as 'Khipp'. It is found in dry, sandy habitat of Pakistan and in several other regions around the world including Asia, Tropical Africa, Western Gulf and Mediterranean countries. It has nutritional value, containing 4 % lipids, 23 % proteins, 28 % carbohydrates, 4 % fibers, vitamin E and several minerals. Traditionally, this plant has been used by several communities for pain, different inflammatory and kidney disorders. Ethno-botanical studies have reported the use of L. pyrotechnica in nephrolithiasis, kidney disorders and induction of diuresis, which requires a detailed pharmacological study to validate the folkloric use of L. pyrotechnica as diuretic. Methods: The 70 % methanolic L. pyrotechnica (Lp.Cr) extract was prepared and qualitatively checked for the presence of various phytochemicals. Phenolic, flavonoid, tannin and saponin contents were quantified. GC-MS analysis of Lp.Cr was also performed. Antioxidant potential of Lp.Cr was evaluated by DPPH, ABTS and nitrite radical scavenging assays. CUPRAC and FRAP assay described the reducing potential of Lp.Cr. Diuretic activity was performed in both acute and prolonged models at different doses followed by the estimation of electrolytes, urea and creatinine levels. The mechanism of diuresis was described by pre-treatment with atropine, l-NAME, indomethacin and carbonic anhydrase inhibition. Results: Lp.Cr. indicated high phenolic and flavonoid contents which correlated with good antioxidant activity. GC-MS analysis showed the presence of 104 compounds from different phytochemical classes. Diuretic activity was performed at 10-300 mg/kg concentrations where the dose of 100 and 300 mg/kg showed good diuretic and saluretic activity comparable to furosemide. Lp.Cr exhibited diuresis both in acute and prolonged study protocols which can be attributed to carbonic anhydrase inhibition, effect on prostaglandins and cholinergic pathways. Conclusion: L. pyrotechnica contained several phytochemicals and exhibited good antioxidant activity. It induced diuresis and saluretic activity which was comparable to furosemide at higher doses. Diuretic activity can be attributed to carbonic anhydrase inhibition, prostaglandin synthesis and cholinergic pathways.

RESUMO

Piper amalago L. is used in Brazilian traditional medicine to treat inflammation, chest pain, and anxiety. This study aimed to investigate the safety and the renal and cardiovascular effects of the volatile oil (VO) and the aqueous (AE) and hydroalcoholic (HE) extracts from P. amalago. The gas chromatography-mass spectrometry analyses identified 47 compounds in the VO, with ß-cyclogermacrene, spathulenol, ß-phellandrene, and α-pinene standing out. Among the 47 compounds also found in AE and HE by liquid chromatography-mass spectrometry, glycosylated flavones, organic acids, amino acids, and amides were highlighted. Some examples of these compounds are methoxy-methylenedioxy cis-cinnamoyl pyrrolidine, methoxy-methylenedioxy trans-cinnamoyl pyrrolidine, and cyclobutene-2,4-bis-(1,3-benzodioxol-5-methoxy-6-yl)-1,3-dicarboxapyrrolidide. The acute toxicity experiments were conducted on female rats (n = 5). The cardiorenal assays (n = 8) and evaluations of vasodilatory effects on the mesenteric vascular bed (n = 5) were conducted on male rats. In either extract or VO, there were no mortality or changes in relative weights or histopathological analysis of the organs. Urinary volume and renal electrolyte excretion were elevated significantly during repeated dose 7-day treatment with different preparations from P. amalago. None of the preparations induced hypotension or changes in cardiac electrical activity. Only HE promoted significant vasodilatory effects in rats' isolated mesenteric vascular beds. These effects were completely abolished in the presence of L-NAME plus 4-aminopyridine. Therefore, P. amalago leaves are safe and present diuretic activity after acute and repeated dose administration over 7 days. Moreover, the HE induced significant vasodilator response in rats' mesenteric vascular beds by NO/cGMP pathway and voltage-dependent K+ channels activation.

RESUMO

There are several Amazonian plant species with potential pharmacological validation for the treatment of acute kidney injury, a condition in which the kidneys are unable to adequately filter the blood, resulting in the accumulation of toxins and waste in the body. Scientific production on plant compounds capable of preventing or attenuating acute kidney injury-caused by several factors, including ischemia, toxins, and inflammation-has shown promising results in animal models of acute kidney injury and some preliminary studies in humans. Despite the popular use of Amazonian plant species for kidney disorders, further pharmacological studies are needed to identify active compounds and subsequently conduct more complex preclinical trials. This article is a brief review of phytocompounds with potential nephroprotective effects against acute kidney injury (AKI). The classes of Amazonian plant compounds with significant biological activity most evident in the consulted literature were alkaloids, flavonoids, tannins, steroids, and terpenoids. An expressive phytochemical and pharmacological relevance of the studied species was identified, although with insufficiently explored potential, mainly in the face of AKI, a clinical condition with high morbidity and mortality.

RESUMO

Euphorbia serpens has been used in central-west region of Argentina in traditional medicine as diuretic plant. The aim of this present study was to evaluate the diuretic activity of E. serpens in-vivo. We used dried aerial parts, and infusions from these were orally administered to Wistar rats. Its effect was evaluated using furosemide as a positive drug and isotonic salt solution as negative control. Their urine output was quantified at several time intervals. The volume of urine excreted and Na+ increased significantly, being similar to furosemide. Mannitol, was the main component in aqueous extracts of E. serpens, and the acetone extract showed the presence of Δ12- oleanane-type triterpenoids compounds, mainly hederagenin. No toxic effects were observed.

RESUMO

BACKGROUND: Artocarpus altilis, A. Champeden, and Artocarpus heterophylus are popular species in Indonesia, and are commonly used as traditional medicine. OBJECTIVE: This study aims to evaluate the diuretic effects of the ethyl acetate fraction of these three species on normotensive Wistar rats. METHODS: The ethyl acetate fraction was prepared by a liquid-liquid extraction method. To evaluate diuretic effects, the sixty rats were divided into normal (distilled water), negative (4.5% NaCl), positive control (furosemide 5 mg/kg), and the testing groups. The testing groups were orally given the ethyl acetate fraction of A. altilis, Artocarpus champeden, and A. heterophylus at three dose levels of 25, 50, and 100 mg/kg. All animals were orally given 4.5% NaCl at a dose of 2 mL/200 g except the normal group; then the animals were given drugs according to group doses. Urine volume and electrolyte levels produced by the testing groups were compared to those of the control group. The concentration and ratio of ions were calculated to determine the natriuretic and carbonic anhydrase activities. RESULTS: The ethyl acetate fractions of the three Artocarpus species at 100 mg/kg dose were more active than the standard furosemide (p < 0.05) to increase urinary excretion. Furthermore, at doses of 50 and 100 mg/kg, the fraction significantly increased the excretion of Na+, K+, and Cl- ions more than the standard (p < 0.05). The testing groups showed good natriuretic and carbonic anhydrase activities. CONCLUSIONS: The ethyl acetate fraction of A. altilis, A. champeden, and A. heterophylus leaves performed good diuretic and natriuretic activities. Therefore, the fractions can be considered as potential natural diuretic medicines.

RESUMO

AIMS: The prognostic value of 'high dose' loop diuretics in advanced heart failure outpatients is unclear. We aimed to assess the prognosis associated with loop diuretic dose in ambulatory patients awaiting heart transplantation (HT). METHODS AND RESULTS: All ambulatory patients (n = 700, median age 55 years and 70% men) registered on the French national HT waiting list between 1 January 2013 and 31 December 2019 were included. Patients were divided into 'low dose', 'intermediate dose', and 'high dose' loop diuretics corresponding to furosemide equivalent doses of ≤40, 40-250, and >250 mg, respectively. The primary outcome was a combined criterion of waitlist death and urgent HT. N-terminal pro-B-type natriuretic peptide, creatinine levels, pulmonary capillary wedge pressure, and pulmonary pressures gradually increased with higher diuretic dose. At 12 months, the risk of waitlist death/urgent HT was 7.4%, 19.2%, and 25.6% (P = 0.001) for 'low dose', 'intermediate dose', and 'high dose' patients, respectively. When adjusting for confounders, including natriuretic peptides, hepatic, and renal function, the 'high dose' group was associated with increased waitlist mortality or urgent HT [adjusted hazard ratio (HR) 2.23, 1.33 to 3.73; P = 0.002] and a six-fold higher risk of waitlist death (adjusted HR 6.18, 2.16 to 17.72; P < 0.001) when compared with the 'low dose' group. 'Intermediate doses' were not significantly associated with these two outcomes in adjusted models (P > 0.05). CONCLUSIONS: A 'high dose' of loop diuretics is strongly associated with residual congestion and is a predictor of outcome in patients awaiting HT despite adjustment for classical cardiorenal risk factors. This routine variable may be helpful for risk stratification of pre-HT patients.

RESUMO

To determine the diuretic activity of Sambucus nigra L. ssp. palmensis (Link) R. Bolli (SP). SP was evaluated in adult female Swiss mice. Urinary excretion volume was measured and the concentration of sodium, potassium, chloride, pH and specific conductance of 3 doses of aqueous extract (35.0, 52.2 and 70.0 mg kg-1) were determined. SP (70.0 mg kg-1) produced a higher urinary excretion (6.41 mL) and diuretic index (15%) than hydrochlorothiazide (HCTZ) (6.27 mL and 12%, respectively). The saluretic index indicates a lower sodium excretion than HCTZ (13%) and inversely proportional to the dose (8% -5%). The same is observed for potassium excretion (0.0172-0.0162 mEq.K+/100 g/6 h), which achieves a lower value than the control group (0.0166 mEq.K+/100 g/6 h), suggesting potassium retention. These results support the use of this plant species as a diuretic in Canarian folk medicine.


Determinar la actividad diurética de Sambucus nigra L. ssp. palmensis (Link) R. Bolli (SP). SP fue evaluada en hembras adultas de ratones Swiss. Se midió el volumen de excreción urinaria y se determinó la concentración de sodio, potasio, cloruro, el pH y la conductividad específica de 3 dosis de extracto acuoso (35,0, 52,2 y 70,0 mg kg-1). SP (70,0 mg kg-1) produjo una excreción urinaria (6,41 mL) e índice diurético (15%) superior a hidroclorotiazida (HCTZ) (6,27 mLy 12%, respectivamente). El índice salurético indica una excreción de sodio inferior a HCTZ (13%) e inversamente proporcional a la dosis (8% -5%). Lo mismo ocurre con la excreción de potasio (0,0172-0,0162 mEq.K+/100 g/6 h) que alcanza un dato inferior al del grupo control (0,0166 mEq.K+/100 g/6 h), lo que sugeriría retención de potasio. Estos resultados apoyan el uso de esta especie vegetal como diurético por la medicina popular canaria.

RESUMO

BACKGROUND: Medicinal plants have been found beneficial in the control and therapy of many ailments as they contain bioactive compounds, and many of them are used as precursors in the biosynthesis of natural medicines. Diuretics are used as a primary treatment in patients with edema associated with liver cirrhosis and kidney diseases, hyperkalemia, hypertension, heart failure, or renal failure. Furthermore, they are also used to increase the excretion of sodium and reduce blood volume. Due to various adverse events associated with synthetic diuretics, there is a need to investigate alternate plant-based bioactive components that have effective diuretic activity with minimal side effects. OBJECTIVE: This review compiled the reported bioactive compounds from different plant sources along with their mechanisms of diuretic activity. METHODS: Different sources were used to collect information regarding herbal plants with therapeutic value as diuretics. These included published peer-reviewed journal articles, scholarly articles from StatPearls, and search engines like Google Scholar, PubMed, Scopus, Springer, ScienceDirect, Wiley, etc. Results: In this review, it was found that flavonoids like rutin, acacetin, naringenin, etc. showed significant diuretic activity in experimental models by various mechanisms, but mostly by blocking the sodium-potassium-chloride co-transporter, while some bioactive compounds showed diuretic actions via other mechanisms as well. CONCLUSION: Research on clinical trials of these isolated bioactive compounds needs to be further conducted. Thus, this review provides an understanding of the potential diuretic bioactive compounds of plants for further research and pharmaceutical applications.

RESUMO

Shenqi Pills, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, have the effect of warming and tonifying the kidney Qi and are mainly used for the treatment of insufficiency of kidney Qi and kidney Yang. According to modern medicine, kidney Qi involves heart function, kidney function, immune function, and so on. The clinical indications of Shenqi Pills include kidney deficiency, abnormal fluid, and abnormal urination, and the last one is classified into little urine, much urine, and dysuria. In clinical settings, Shenqi Pills can be applied for the treatment of heart failure, renal failure, cardiorenal syndrome, and diuretic resistance, as well as endocrine, urological, orthopedic, and other chronic degenerative diseases. Shenqi Pills are ideal prescriptions for the weak constitution and emergency treatment. It is of great value and significance to carry out in-depth research on the connotation of the classic articles by integrating TCM and western medicine based on "pathogenesis combined with pathology and drug properties combined with pharmacology".

RESUMO

Hammada articulata is a plant widely used by the locals of the Algerian Sahara for multiple medicinal purposes. However, little was known about its chemical composition and the mechanisms of its bioactivity. For this purpose, the derived extracts [chloroform (CHCl3), ethyl acetate (EtOAc) and n-butanol (n-BuOH)] of the 80% ethanol extract of its aerial parts, were evaluated for their anti-inflammatory, diuretic, and anti-hyperglycemic activities in vivo. A preliminary phytochemical screening of H. articulata extracts showed the presence of a variety of secondary metabolites. RP-HPLC/DAD was used to analyze some fractions obtained by fractionation of the three derived extracts, by column chromatography and chosen because of the abundance and simplicity of their chemical composition. The fractions obtained from EtOAc and n-BuOH extracts showed a particular richness in phenolic compounds mainly naringenin, quercetin, kaempferol, myricetin, and rutin, which were known for their many interesting biological activities. The three derived extracts from H. articulata were assessed for their anti-inflammatory activity in the carrageenan-induced edema model in rats and their diuretic activity using hydrochlorothiazide (HCTZ) as a diuretic reference. All extracts showed considerable anti-inflammatory activity; the highest was registered in the group treated with the n-BuOH extract. However, for the diuretic activity, only the chloroform extract was active, with a diuretic spectrum similar to that of the standard diuretic HCTZ. The anti-hyperglycemic effect was carried out on the three derived extracts administered orally at a dose of 200 mg/kg, using the glucose tolerance test after gavage with the extracts. The EtOAc and n-BuOH extracts showed significant anti-hyperglycemic activity, improving oral glucose tolerance in normal rats.

RESUMO

Xiphidium caeruleum Aubl. is traditionally used in Cuba as an analgesic, anti-inflammatory, antilithiatic and diuretic remedy. Here we studied the pharmacognostic parameters of the leaves of X. caeruleum, the preliminary phytochemical composition, diuretic activity and acute oral toxicity of the aqueous extracts from the leaves of plants collected in the vegetative (VE) and flowering (FE) stages. The morphological characteristics and physicochemical parameters of leaves and extracts were determined. The phytochemical composition was assessed by phytochemical screening, TLC, UV, IR and HPLC/DAD profiles. The diuretic activity was evaluated in Wistar rats and compared to furosemide, hydrochlorothiazide and spironolactone. Epidermal cells, stomata and crystals were observed on the leaf surface. Phenolic compounds were identified as the main metabolites, including phenolic acids (gallic, caffeic, ferulic and cinnamic acids) and flavonoids (catechin, kaempferol-3-O-glucoside and quercetin). VE and FE showed diuretic activity. The activity of VE was similar to furosemide, and the activity of FE resembled spironolactone. No acute oral toxicity was observed. The presence of flavonoids and phenols in VE and FE may explain at least in part the traditional use and provide some insight into the reported ethnomedical use as a diuretic. Because of the differences in polyphenol profiles between VE and FE, further studies should be carried out to standardize the harvesting and extraction conditions in order to use X. caeruleum leaf extract as herbal medicine.

RESUMO

Thymus comosus Heuff ex. Griseb. (Lamiaceae) is a wild thyme species endemic for Romanian Carpathian areas, frequently collected as substitute for collective herbal product Serpylli herba, cited as antibacterial and diuretic remedy in traditional medicine. The present study aimed to evaluate the in vivo diuretic effect and in vitro antimicrobial properties of three herbal preparations (infusion-TCI, tincture-TCT and an hydroethanolic extract prepared through an optimized ultrasound-assisted method-OpTC) obtained from the aerial parts of T. comosus Heuff ex. Griseb, also evaluating their comprehensive phenolic profile. In vivo diuretic effect was tested using Wistar rats treated orally with each herbal preparation (125 and 250 mg/kg dispersed in 25 ml/kg isotonic saline solution) and quantified based on cumulative urine output (ml), diuretic action and diuretic activity. Additionally, sodium and potassium excretion were monitored using a potentiometric method with selective electrodes. In vitro antibacterial and antifungal activities were assessed using p-iodonitrotetrazolium chloride assay against six bacterial strains and six fungal strains by monitoring minimum inhibitory concentration (MICs), minimum bactericidal concentrations (MBCs) and minimum fungicidal concentrations (MFCs). Finally, phenolic profile of the aforementioned herbal extracts was evaluated using an ultra-high-pressure liquid chromatography (UHPLC) coupled with high-resolution mass spectrometry (HRMS) method to check the impact of the different preparations on the most abundant and significant compounds. All the extracts exerted a mild diuretic action, TCT and OpTC inducing the most intense diuretic effect. Both herbal preparations produced a statistically significant, dose-dependent and gradual increase of the urine output, the effect being more intense at 24 h (6.63-7.13 ml/24 h). Potentiometric evaluation of urine samples collected from treated rats revealed a clear and mild natriuretic and kaliuretic effect after the administration. In terms of antimicrobial activity, E. coli (MIC-0.38 mg/ml), B. cereus (MIC-0.75 mg/ml)), Penicillium funiculosum and P. verrucosum var. cyclopium (MIC-0.19 mg/ml) showed the greater sensitivity to the tested extracts, respectively. UHPLC-HRMS screening showed that the bioactive potential of T. comosus herbal preparations was likely related to the higher amounts of phenolic acids (including rosmarinic acid), flavonoids (mainly flavones and derivatives) and other phenolics (such as different isomers of salvianolic acids) in their composition. The obtained results support the ethnopharmacological evidence regarding the mild diuretic and antibacterial potentials of the endemic wild thyme T. comosus, this study being the first one that assessed the aforementioned bioactivities for this species.

RESUMO

Leonurus japonicus Houtt. has been traditionally used to treat many ailments. This study evaluated the activating blood circulation, anti-inflammatory, and diuretic effects of L. japonicus extract (LJ) and identified its phytochemicals. In this work, the phytochemicals in LJ were identified using liquid chromatography mass spectrometry. Rats were randomly assigned to three groups (n=8): Control group was treated with saline, while the Model group (saline) and LJ group (426 mg/kg) had induced traumatic injury. All rats were treated with once by daily oral gavage for one week. The biochemical indices and protein expression were measured. Herein, 79 constituents were identified in LJ, which were effective in elevating body weight, food consumption, water intake, and urinary excretion volume, as well as in ameliorating traumatic muscle tissues in model rats. In addition, LJ prominently decreased the contents of plasma viscosity, platelet aggregation rate, thrombin time, prothrombin time, activated partial thromboplastin time, fibrinogen, thromboxane B2 (TXB2), TXB2/6-keto-prostaglandin F1α (6-keto-PGF1α), urokinase-type plasminogen activator (u-PA), plasminogen activator inhibitor 1 (PAI-1), PAI-1/tissue-type PA (t-PA), and PAI-1/u-PA, while significantly increasing antithrombin III, 6-keto-PGF1α, and t-PA contents. Furthermore, LJ notably inhibited tumor necrosis factor alpha, interleukin 6 (IL-6), IL-8, angiotensin II, antidiuretic hormone, aldosterone, aquaporin 1 (AQP1), AQP2, and AQP3 levels, and markedly elevating IL-10 and natriuretic peptide levels. Finally, LJ markedly reduced the protein expression of AQP1, AQP2, and AQP3 compared to the model group. Collectively, LJ possessed prominent activating blood circulation, anti-inflammatory, and diuretic effects, thus supporting the clinical application of L. japonicus.

RESUMO

Shenqi Pills, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, have the effect of warming and tonifying the kidney Qi and are mainly used for the treatment of insufficiency of kidney Qi and kidney Yang. According to modern medicine, kidney Qi involves heart function, kidney function, immune function, and so on. The clinical indications of Shenqi Pills include kidney deficiency, abnormal fluid, and abnormal urination, and the last one is classified into little urine, much urine, and dysuria. In clinical settings, Shenqi Pills can be applied for the treatment of heart failure, renal failure, cardiorenal syndrome, and diuretic resistance, as well as endocrine, urological, orthopedic, and other chronic degenerative diseases. Shenqi Pills are ideal prescriptions for the weak constitution and emergency treatment. It is of great value and significance to carry out in-depth research on the connotation of the classic articles by integrating TCM and western medicine based on "pathogenesis combined with pathology and drug properties combined with pharmacology".

RESUMO

Background: Lagopsis supina (Steph. ex Willd.) Ikonn.-Gal. has been a traditional Chinese medicine (TCM) for the treatment of blood stasis, inflammation, and diuresis. Moreover, Huo Xue Li Shui theory was an important TCM theory that used to treat many ailments. Nevertheless, the scientific connotation of this theory has not been clearly elucidated so far. Aim of the study: The aim of this study was to explore the scientific connotation of Huo Xue Li Shui with promoting blood circulation and removing blood stasis (PBCRBS), anti-inflammatory and diuretic effects in trauma-induced blood stasis model (TBSM) rats, taking microporous adsorption resin with water (LSB) and 30% ethanol (LSC) elution fractions from L. supina as a classical demonstration. Materials and methods: 48 rats were randomly assigned into six groups (n = 8/group): the control group, the model group, and model groups treatment with LSB or LSC. The biochemical parameters and protein expression were measured using kit method and Western blot assay, respectively. Results: Both LSB and LSC were effective in elevating body weight, food consumption, and water intake in model rats. In PBCRBS efficacy evaluation, LSB and LSC remarkably improved histopathological tissues. On the other hand, LSB and LSC prominently decreased the contents of plasma viscosity, platelet aggregation rate, thrombin time, prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, thromboxane B2, thromboxane B2/6-keto-prostaglandin F1α, urokinase-type plasminogen activator (u-PA), plasminogen activator inhibitor-1(PAI-1), PAI-1/tissue-type plasminogen activator (t-PA), and PAI-1/u-PA, while significantly enhanced the contents of antithrombin III, 6-keto-prostaglandin F1α, and t-PA. In parallel, LSB and LSC obviously down-regulated the levels of tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and IL-8, and remarkably up-regulated the level of IL-10. In determining diuretic activities, LSB and LSC prominently elevated urinary excretion volume and the level of atriopeptin, and remarkably reduced the levels of angiotensin II, anti-diuretic hormone, aldosterone, aquaporin 1 (AQP1), AQP2, and AQP3. In addition, LSB and LSC clearly suppressed protein expressions of AQP1, AQP2, and AQP3. Finally, LSB and LSC did not caused urinary pH, Na+, and Cl- electrolytes and had minor effects on K+ and Ca2+ concentrations. Conclusions: LSB and LSC exhibited prominent PBCRBS, anti-inflammatory, and diuretic effects in TBSM rats, thereby supported the traditional folk use of L. supina. This study successfully provided an experimental basis for the scientific connotation of Huo Xue Li Shui.

RESUMO

Banana central core stem powder (CCSP) of seven varieties were studied to elucidate their functional, therapeutic properties and bioactiveprofiling.CCSP recorded whiteness index in the range of 75.80-80.78.Hauser-ratio (1.12-1.26), Carr-index (10.91-20.75) and aw(0.15-0.22) revealed good flowability and storage-life. A fair amount of insoluble dietary fiber (45.58-51.38 %) was observed in CCSP.Nendran and Rasthali varieties recorded higher antioxidant activities. CCSP registered higher amounts of minerals like potassium (571.84-978.22), calcium (110.65-180.55) and lower sodium (34.10-43.70).Aqueous methanolic extract of Nendran CCSP showed lesser viability of tumour cells (44.32 %) with the concentration of 500 µg/mL and IC50of 177 µg/mL.After seven days of incubation, 5 % Nendran CCSP extract, resulted in higher (78.68 %) reduction of struvite formation.Steroids, terpene and acetate compounds were identified in addition to organic acids and aldehydes.Low sodium, higher dietary fiber and bioactive properties make banana CCSP a cheaper material to contemplate in food-processing and pharmaceutical industries.
