ABSTRACT

Prunella vulgaris(PV) is an edible and traditional medicinal herb which has a wide range application in fighting inflammation and oxidative stress, and protecting liver. Now it has been used to treat various types of liver diseases and has significant clinical efficacy. This study aims to investigate the effects of PV on ethanol-induced oxidative stress injury in rats and its metabolic mechanism. The rats were divided into control group, model group, PV group, and VC group. The liver protection of PV was identified by measuring pharmacological indexes such as antioxidant and anti-inflammatory activity. The metabolic mechanism of long-term ethanol exposure and the metabolic regulation mechanism of PV treatment were studied by LS-MS metabonomics. The pharmacological investigation indicated that ethanol could significantly decrease the contents of SOD, GSH-Px, CAT and other antioxidant enzymes in liver and increase the content of MDA. At the same time, PV could significantly reduce the contents of inflammatory factors(TNF-α, IL-6 and IL-1β) and liver function markers(ALT, AST, ALP) in serum. What's more, long-term ethanol exposure could significantly cause liver injury, while PV could protect liver. Metabolomics based on multiple statistical analyses showed that long-term ethanol exposure could cause significant metabolic disorder, and fatty acids, phospholipids, carnitines and sterols were the main biomarkers. Meanwhile, pathway analysis and enrichment analysis showed that the β oxidation of branched fatty acids was the main influencing pathway. Also, PV could improve metabolic disorder of liver injury induced by ethanol, and amino acids, fatty acids, and phospholi-pids were the main biomarkers in PV treatment. Metabolic pathway analysis showed that PV mainly regulated metabolic disorder of ethanol-induced liver injury through phenylalanine, tyrosine and tryptophan biosynthetic pathways. This study could provide a new perspective on the hepatoprotective effect of natural medicines, such as PV.

ABSTRACT

To systemically evaluate the clinical efficacy and safety of oral preparation of Xiakucao with levothyroxine(LT4) on Hashimoto's thyroiditis(HT), so as to provide the evidence for its clinical application in the future. All the included studies were retrieved from four Chinese databases and three English databases from their inception to December 2019. ROB assessment tool of cochrane system and the evidence classification recommended by GRADE were used to evaluate the quality of evidences in all included studies. RevMan 5.3 was used for Meta-analysis of the outcomes. Software TSA 0.9(trail sequential analysis) was used to estimate the sample size for Meta-analysis. The results showed that 11 randomized controlled trials and totaling 1 215 patients were included. Preparation of Xiakucao combined with LT4 was adopted as intervention in experimental group, while patients in control group were treated with LT4 alone. Meta-analysis results showed that as compared with control group, the rate of total efficacy in experimental group was significant improved, including improvement of thyroid function and thyroid autoantibodies, shrinkage of thyroid gland and nodule, and improvement of clinical symptoms such as fatigue and cold intolerance(RR=1.15, 95%CI[1.09, 1.21]). The experimental group significantly decreased the serum level of thyroperoxidase antibody TPO-Ab(SMD=-0.91, 95%CI[-1.40,-0.41]), and reduced the size of left thyroid lobe(MD=-1.46, 95%CI[-1.82,-1.11]), right thyroid lobe(MD=-1.45, 95%CI[-1.96,-0.94]) and isthmus of thyroid gland(MD=-1.08, 95%CI[-1.20,-0.95]). After evaluation based on GRADEpro, the results showed that the evidence quality of all included studies was low or very low. The result of TSA showed that the cumulative sample size had reached the expected value. However, the pooled results may be affected by one study with high bias risk, with not so high effect intensity of evidences. From this review, we can see that in treatment of HT, intervention of preparation of Xiakucao combined with LT4 has advantages on improvement of clinical efficiency, decreasing serum level of TPO-Ab and shrinkage of thyroid gland. However, due to the quality of evidence, more rigorously designed and high-quality trials are needed in the future to verify the clinical efficacy and safety of preparation of Xiakucao in treating HT.

ABSTRACT

BACKGROUND: Prunella vulgaris L. has been an important medicinal plant for the treatment of thyroid gland malfunction and mastitis in China for over 2000 years. There is an urgent need to select effective wavelengths for greenhouse cultivation of P. vulgaris as light is a very important factor in P. vulgaris growth. Here, we described the effects of natural light (control) and UV solar exclusion on the morphological and physiological traits, secondary metabolites contents and antioxidant activities of P. vulgaris. RESULTS: The results showed that UV solar exclusion resulted in remarkable alterations to morphological and biomass traits; significantly reduced the chlorophyll a, chlorophyll b and total chlorophyll contents; significantly enhanced the ratio of chlorophyll a to b; and significantly increased the carotenoid and anthocyanin contents in P. vulgaris. UV solar exclusion significantly increased the catalase (CAT) and peroxidase (POD) activities, increased superoxide dismutase (SOD) and ascorbate peroxidase (APX) activities and slightly decreased the glutathione (GSH) content. UV solar exclusion significantly increased the soluble sugar and H2O2 contents and increased the soluble protein content but significantly decreased the proline content and slightly decreased the MDA content. The secondary metabolite contents (total phenolics, rosmarinic acid, caffeic acid, hyperoside, ursolic acid and oleanolic acid) and in vitro antioxidative properties (DPPH· and ABTS·+scavenging activities) were significantly increased in P. vulgaris spicas under UV solar exclusion. Additionally, the total polysaccharide and total flavonoids contents were slightly increased by UV solar exclusion. The salviaflaside content was significantly reduced by UV solar exclusion. CONCLUSION: Our study demonstrated that P. vulgaris activates several antioxidant defence systems against oxidative damage caused by UV solar exclusion.

ABSTRACT

Pancreatic lipase (PL) inhibitors were firstly screened from Prunella vulgaris with PL immobilized on carboxylic acid-terminated magnetic nanoparticles, then these possible inhibitors were identified by LC-MS/MS and mixed standards. Finally, their inhibitory effects and types on PL were tested by p-nitrophenol method. The results showed that four PL inhibitors were screened out from P. vulgaris and confirmed by LC-MS/MS and mixed standards. The IC₅₈ and inhibition types were as follows: caffeic acid [(252.3±3.6) mg·L⁻¹, anti-competitive inhibition], rutin [(91.2±1.6)mg·L⁻¹, competitive inhibition], hesperidin [(31.5±4.4) mg·L⁻¹, competitive inhibition] and ursolic acid [(41.3±2.2) mg·L⁻¹, competitive inhibition]. Their inhibitive types and abilities on PL were related to their molecular size, hydrophobicity and the number of hydrogen bond with PL triplet.

ABSTRACT

BACKGROUND: Prunella vulgaris L. is a medical plant cultivated in sloping, sun-shaded areas in China. Recently, owing to air-environmental stress, especially drought stress strongly inhibits plant growth and development, the appropriate fertilizer supply can alleviate these effects. However, these is little information about their effects on P. vulgaris growing in arid and semi-arid areas with limited water and fertilizer supply. RESULTS: In this study, water stress decreased the photosynthetic pigment contents, inhibited photosynthetic efficiency, induced photodamage in photosystem 2 (PS2), and decreased leaf instantaneous WUE (WUEi). The decreased net photosynthetic rate (Pn) under medium drought stress compared with the control might result from stomatal limitations. However, fertilizer supply improved photosynthetic capacity by increasing the photosynthetic pigment contents and enhancing photosynthetic efficiency under water deficit. Moreover, medium fertilization also increased WUEi under the two water conditions, but fertilizer supply did little to alleviate the PS2 photodamage caused by drought stress. Hence, drought stress was the primary limitation in the photosynthetic process of P. vulgaris seedlings, while the photosynthetic characteristics of the seedlings exhibited positive responses to fertilizer supply. CONCLUSIONS: Appropriate fertilizer supply is recommended to improve photosynthetic efficiency, enhance WUEi and alleviate photodamage under drought stress.

ABSTRACT

The present study was designed to analyze the major constituents in Prunellae Spica and establish a method for simultaneous determination of two constituents contained in Prunellae Spica. High performance liquid chromatography coupled with time-of-flight mass spectrometry (HPLC-QTOF-MS/MS) technique was used to identify the constituents in the extractive of Prunellae Spica. High performance liquid chromatography coupled with evaporative light scattering detection (HPLC-ELSD) was used to simultaneously quantify two kinds of constituents contained in Prunellae Spica. Principal component analysis (PCA) was applied to compare the similarity and difference among samples from different regions of China. In the present study, 22 compounds were identified and some new fragmental pathways of triterpenic acids were discovered. An accurate and reliable HPLC-ELSD method was developed and validated for the first time to simultaneously quantify multiple constituents, including rosmarinic acid, maslinic acid, corosolic acid, betulin, oleanolic acid, and ursolic acid in the extract of Prunellae Spica. (PCA) revealed some similarities and differences among different samples from different regions of China. In conclusion, our results from this study would be helpful in establishing a scientific and rational quality control method for Prunellae Spica.

ABSTRACT

Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness). The results indicated that bitter and slightly bitter amino acids have the greatest impacts on the sense of Spica Prunellae.

ABSTRACT

To separate and identify chemical signals which induce Thesium chinense haustorium formation, the components of T. chinense roots secretion collected with XAD-4 resin were detected by GC-MS. The effect of DMBQ as exogenous signals to induce haustorium formation in T. chinense was studied. Fifty-three compounds of 9 types had been detected, including hydrocarbons, esters, organic acids, ketones, alcohols, nitrogen containing compounds, phenolic acids, aldehyde and quinine. It is worth noting that the 2, 5-di-tert-butyl-1,4-benzoquinone has the core structure of 1,4-benzoquinone, which may play an important role in the parasitic relationship of Prunella vulgaris and T. chinense: DMBQ worked effectively on inducing haustoria, but induction effects vary widely in different concentrations. DMBQ with the concentration of 1 μmol x L(-1) showed the best effect of the inducing ability with a ratio of 110.52 when treated to induce haustoria.

ABSTRACT

<p><b>BACKGROUND</b>The effects of triterpenic acid from Prunella vulgaris L. (TAP) on diabetes and its mechanism are uncertain. The aim of this study was to investigate the effects of TAP on antihyperglycemic, antioxidant, and pancreas-protective in streptozotozin (STZ)-diabetic rats.</p><p><b>METHODS</b>The diabetic model was produced by injection of 60 mg/kg STZ. Blood was drawn from the tail vein of rats after 72 hours. Rats with blood glucose ≥ 16.7 mmol/L were considered diabetic. Diabetic rats were randomly divided into four groups: (1) Diabetes rat (STZ), (2) Diabetic rats treated with 50 mg/kg of triterpenic acid from Prunella vulgaris L (STZ + TAP50), (3) Diabetic rats treated with 100 mg/kg TAP (STZ + TAP100), and (4) Diabetic rats treated with 200 mg/kg TAP (STZ + TAP200). Normal rats (n = 10) acted as the control group (NC). TAP was administered by the intragastric route once each day for six weeks. Body weight and the concentration of blood glucose (BG) were measured after three and six weeks. Fructosamine (FMN), malondialdehyde (MDA), and nitric oxide (NO), and the activities of nitric oxide synthase (NOS) and superoxide dismutase (SOD) in serum were determined after six weeks using commercially available kits following the manufacturer's instructions. Pathologic changes in pancreatic β-cells were also investigated by microscopic examination after hematoxylin-eosin (HE) staining. The level of SOD mRNA in pancreatic β-cells was measured by polymerase chain reaction (PCR).</p><p><b>RESULTS</b>The levels of BG, FMN, NO, and MDA and the activities of NOS in serum in the four diabetes groups were significantly increased compared with the control group (P < 0.01). The activity of SOD in serum and the body weight was significantly decreased compared with the control group (P < 0.01). After administration of TAP to diabetic rats for six weeks, the body weight and the levels of BG, FMN, MDA, NO and the activity of NOS in serum decreased significantly compared with the STZ group in a dose-dependent manner. The activity of SOD in serum and body weight increased significantly compared with the STZ group in a dose-dependent manner. In addition, diabetic rats showed a significant decrease in SOD mRNA expression in pancreatic β cells. However, these changes were reversed by TAP. Histopathological examination also showed the protective effect of TAP on pancreatic β cells.</p><p><b>CONCLUSIONS</b>Triterpenic acid from Prunella vulgaris L. has an anti-diabetic effect, by controlling blood glucose and antioxidants, and has a protective effect on the pancreas.</p>

ABSTRACT

Prunella vulgaris is a perennial herb whose dry spike is used for medicine in China. It is also a very important traditional medicine. Current study was conducted to the biomass components factors of P. vulgaris in the different ecological environments for the development and protection. The results showed that the contribution factor of the production in different environments was significant differences. In favorable environment, the length of leaf, numbers of leaves, height, reproductive branch number of individuals gave the greatest contribution. In transitional habitats, the diameter of stem and spike, the length of leaf contributed the most. While in the undergrowth and dry hillside, the length of root, the width of leaf, the length of spike were the main factors for biomass.

ABSTRACT

Prunella vulgaris L. (Labiatae) contains a variety of structurally diverse natural products, primarily rosmarinic acid (RA), ursolic acid (UA) and oleanolic acid (OA), which possess a wide array of biological properties. In the present study, P. vulgaris was harvested at three developmental stages (vegetative, full-flowering and mature-fruiting stages), dissected into stem and leaf tissues and assayed for chemical contents using high performance liquid chromatography. Significant changes in the concentrations of the major secondary metabolites (RA, UA and OA) were observed at the different development stages. The highest concentrations of RA, UA and OA were found at the full-flowering stage (15.83 mg/g dry weight (DW) RA, 1.77 mg/g DW UA and 0.65 mg/g DW OA). Among the different aerial parts of the plant, the concentrations of RA, UA and OA were higher in the leaves than in the stems at the different developmental stages. These results suggest that the full-flowering stage is characterized by the highest concentrations of bioactive compounds. Therefore, this stage may be the optimum point for harvesting P. vulgaris plants. In additional, the leaves of P. vulgaris demonstrated higher RA, UA and OA concentrations than the stems, suggesting higher utilization potential.

ABSTRACT

<p><b>OBJECTIVE</b>To study the influence of host species on growth and development and active component content of Thesium chinense.</p><p><b>METHOD</b>Plant morphology and active component content of T. chinense grown with different hosts were measured. The hosts were evaluated by using index-sum method.</p><p><b>RESULT</b>Hosts significantly promoted the growth of T. chinense by increasing height, per plant weight, stem diameter, leaf area, the number of seed and haustorium,and decreased RW/SW ratio compared to without host treatment. Considerable differences existed among the effect of different host species treatments. Synthetical evaluation score of Gnaphlium affine was the highest (37), followed by Imperata cylindrical and Prunella vulgaris (36). It is suggested that they were superior hosts for T. chinense. But the scores of Triticum aestivum (25) and Eremochloa ophiuroides (17) were lower, so they were unsuited hosts for T. chinense.</p><p><b>CONCLUSION</b>Hosts significantly promoted the growth of T. chinense. Considerable differences existed among the growth and development of T. chinense grown with different hosts, as well as active component content. Gnaphlium affine, Imperata cylindrical and Prunella vulgaris were superior hosts for T. chinense. While Triticum aestivum and Eremochloa ophiuroides were unsuited hosts for T. chinense.</p>

ABSTRACT

To study the effects of triterpenoid components from Prunella asiatica on phase II detoxifying enzymes and protein expression in vitro and in vivo. Normal human bronchial epithelial (NHBE) cell model was used in vitro, and the mouse model of Kunming (KM) mice was used in vivo. CDNB assay was used to measure the activity of GST. NADPH and DCIP was used to detect the activity of NQO1. DTNB colorimetric assay was used to detect GSH. Western blot was use to detect the protein expression of NQO1. We found that triterpenoid components from P. asiatica could increase the activity of GST, NQO1 and GSH in NHBE cells and KM mice. NQO1 protein expression can also be increased in vitro. The study suggests that triterpenoid components from P. asiatica can prevent the lung cancer by regulating the body phase II detoxification enzyme activity and protein expression.
