Exploring the therapeutic potential of Prinsepia utilis Royle seed oil: A comprehensive study on chemical composition, physicochemical properties, anti-inflammatory, and analgesic activities.

ETHNOPHARMACOLOGICAL RELEVANCE: Prinsepiautilis (PU) Royle, native to the Himalayan region, is a deciduous thorny shrub with numerous traditional uses of its roots, leaves and seeds for treatment of conditions such as rheumatic pain, joint pain, arthritis, and inflammation. AIM OF THE STUDY: Keeping in mind the growing demand of products of natural origin as alternate medicine, the present study was undertaken to scientifically validate for the first time the traditional claims of healing pain and inflammation by evaluating the fatty oil isolated from the seeds using established in vitro and in vivo models. MATERIALS AND METHODS: PU Seeds were Soxhlet extracted using n-hexane and fatty oil was isolated. Chemical composition of the oil was established with the aid of Gas Chromatography-Flame Ionization Detection (GC-FID) and Gas Chromatography-Mass Spectrometry (GC-MS). The oil was then subjected to in vitro anti-inflammatory activity by following the established protocols of trypsin inhibitory and bovine serum albumin denaturation assays. The acute toxicity of the oil was also studied using OECD guidelines 423. The anti-inflammatory property of the oil was further evaluated using carrageenan-induced and formalin-induced edema in the rat paw. Moreover, hot plate latency and tail immersion assay were employed to evaluate analgesic activity of the oil. To establish the quality of the oil, various physicochemical properties were also studied. RESULTS: GC-FID and GC-MS analysis of the oil revealed the presence of linoleic acid (59.06 ± 0.00%), oleic acid (28.11 ± 0.01%), palmitic acid (9.51 ± 0.01%) and stearic acid (3.32 ± 0.01%). In vitro trypsin inhibitory and bovine serum albumin denaturation assay revealed dose-dependent notable activity of the oil with IC50 value of 63.57 µg/mL and 518.14 µg/mL, respectively. The physico-chemical characterization demonstrated that the oil possesses a low acidity and a high oxidative stability index. The oil was found to be non-toxic and displayed effective anti-inflammatory activities with significant inhibition till 4 h in carrageenan-induced and formalin-induced rat paw edema at maximum tested dose of 200 mg/kg b.w. The oil also exhibited significant results in hot plate latency and tail immersion assay with positive effects showing up to 4 h after dose administration. CONCLUSION: These findings, besides supporting the traditional claims, suggest that P. utilis seed oil has potential therapeutic applications as a natural anti-inflammatory and analgesic agent. Further studies are warranted to explore its mechanisms of action and potential use in pharmaceutical and nutraceutical industries.

In vitro and in vivo anti-inflammatory activity of Cupressus torulosa D.DON needles extract and its chemical characterization.

ETHNOPHARMACOLOGICAL RELEVANCE: Cupressus torulosa (family Cupressaceae), widely distributed in the north western Himalayan region of India, is a coniferous aromatic tree with various traditional uses of its aerial parts. Its needles have been used for anti-inflammatory, anticonvulsant, antimicrobial, and wound-healing properties. AIM OF THE STUDY: The study aimed at investigating the previously unknown anti-inflammatory activity of the hydromethanolic extract of the needles employing in vitro and in vivo assays and scientifically validate traditional claim of their use in treatment of inflammation. Chemical characterization of the extract with the aid of UPLCQTOFMS was also of interest. MATERIALS AND METHODS: C. torulosa needles were first defatted with hexane and sequentially extracted with chloroform and 25% aqueous methanol (AM). Since the presence of phenolics (TPCs, 208.21 ± 0.95 mg GAE/g needles) and flavonoids (TFCs, 84.61 ± 1.21 mg QE/g needles) was observed in the AM extract only, it was chosen for biological and chemical examinations. Acute toxicity of the AM extract on female mice was evaluated following the OECD guideline 423. In vitro anti-inflammatory activity of the AM extract was examined using egg albumin denaturation assay while carrageenan-induced paw edema and formalin-induced paw edema models at doses of 100, 200 and 400 mg/kg po were used to determine the in vivo activity of the AM extract on Wistar rats of either sex. The components of the AM extract were analyzed by UPLC-QTOF-MS method using non-targeted metabolomics approach. RESULTS: AM extract was found to be non-toxic at 2000 mg/kg b.w. with no signs of abnormal locomotion, seizures and writhing. The extract demonstrated promising in vitro anti-inflammatory activity (IC50 160.01 µg/mL) compared to standard diclofenac sodium (IC50 73.94 µg/mL) in egg albumin denaturation assay. In carrageenan-induced paw edema and formalin-induced paw edema tests the extract showed significant anti- inflammatory activity (57.28% and 51.04% inhibition of paw edema, respectively) at the dose of 400 mg/kg p.o. after 4 h in comparison to the standard diclofenac sodium which displayed 61.39% and 52.90% inhibition, respectively, at the dose of 10 mg/kg p.o. after 4 h in these models. A total of 63 chemical constituents, majority of them being phenolics, were found in the AM extract of the needles. Two compounds namely monotropein (iridoid glycoside), (±)12-HETE (eicosanoid) and fraxin (coumarin glycoside) were reported to have anti-inflammatory effect. CONCLUSIONS: For the first time our study demonstrated that hydro-methanolic extract of C. torulosa needles exhibit anti-inflammatory activity thereby supporting their traditional use in the treatment of inflammatory disorders. UPLCQTOFMS assisted chemical profile of the extract was also unveiled.

Antiallergic activity of Aristolochia bracteolata Lank in animal model.

Antiallergic activity of Aristolochia bracteolata was evaluated by using compound 48/80 induced anaphylaxis, dermatitis rhinitis and pruritus, as a preclinical model for acute phase of hypersensitivity reactions. The late phase hypersensitivity was evidenced by considering toluidine diisocyanate induced volume of bronchoalveolar fluid secretion and its inhibition. The possible antiallergic mechanism was evaluated by using compound 48/80 induced mast cell activation and estimated serum nitric oxide (NO), rat peritoneal fluid NO, bronchoalveolar fluid NO and blood histamine levels. The present study implied that the chloroform extract of Aristolochia bracteolata had potent and significant inhibitory effect on compound 48/80 induced pruritus and dermatitis activity in Swiss albino mice. It showed significant effect in toluidine diisocyanate induced rhinitis in swiss albino mice. Mast cell membrane stabilization activity was also observed in compound 48/80 induced mast cell activation. A significant reduction was observed in serum nitrate levels, rat peritoneal fluid nitrate levels and BAL nitrate levels. The extract was also found to possess significant inhibitory effect on blood histamine levels. It could be concluded that chloroform extract of A. bracteata possess potent antiallergic activity, possibly through mast cell membrane stabilization, inhibiting NO and histamine pathway.

Anti-urolithiatic effects of Punica granatum in male rats.

ETHNOPHARMACOLOGICAL RELEVANCE: The traditional use of Punica granatum has been reported to regulate urine discharge and controls the burning sensation of urine. MATERIALS AND METHODS: Animals model of calcium oxalate urolithiasis was developed in male rats by adding ethylene glycol 0.75% in drinking water. The Punica granatum chloroform extract (PGCE) and Punica grantum methanol extract (PGME) orally at 100, 200 and 400mg/kg, respectively, were administered along with ethylene glycol for 28 days. On 28 day, 24h urine was collected from individual rats and used for estimation of urine calcium, phosphate and oxalate. The serum creatinine, urea and uric acid levels were estimated in each animal. The kidney homogenate was used for the estimation of renal oxalate contents. The paraffin kidney sections were prepared to observe the CaOx deposits. RESULTS: The ethylene glycol control (Gr.-II) had significant (P<0.001 vs. normal) increase in levels of urine oxalate, calcium and phosphate, serum creatinine, urea and uric acid and renal tissues oxalates, as compared to normal (Gr.-I). The paraffin kidney sections show significant histopathological changes. The treatment of PGCE and PGME at 100, 200 and 400mg/kg doses, significantly (P<0.001 vs. control) decreased the urine oxalate, calcium and phosphate, renal tissue oxalates and serum creatinine, urea and uric acid, in EG induced urolithiasis after 28 days. CONCLUSIONS: The PGCE and PGME at the doses of 400mg/kg, found to be more effective in decreasing the urolithiasis and regeneration of renal tissues in male rats.

Free Radical Scavenging Activity of Calotropis gigantea on Streptozotocin-Induced Diabetic Rats.

Swarnabhasma, an Ayurvedic preparation containing Calotropis gigantea R. Br. (Asclepiadaceae) is extensively used by Ayurvedic physicians for treatment of diabetes mellitus, bronchial asthma, rheumatoid arthritis and nervous disorders. In the present study, we report the effect of chloroform extracts of Calotropis gigantea leaf and flower on free radical scavenging activity, and lipid profile in streptozotozin-induced diabetic rats. The lipid peroxidation, superoxide dismutase, and catalase were measured in liver homogenate and serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, alkaline phosphatase, lipid profile were measured in blood serum. Administration of single dose of streptozotozin (55 mg/kg, i.p.) caused significant increases in lipid peroxidation, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, alkaline phosphatase, cholesterol and triglyceride levels, while superoxide dismutase and catalase levels were significantly decreased. Further, administration of chloroform extracts of Calotropis gigantea leaf and flower to streptozotocin-induced diabetes rats at a dose of 10, 20 and 50 mg/kg orally for 27 d lead to a significant decrease in lipid peroxidation, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, alkaline phosphatase, cholesterol and triglyceride levels. Consequently, superoxide dismutase and catalase levels were significantly increased. Glibenclamide was used as a positive control (10 mg/kg). It was observed that the effect of chloroform extracts of Calotropis gigantea on alkaline phosphatase, cholesterol, superoxide dismutase, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, levels are comparable to that of those produced by the positive control.

Evaluation of antipyretic activity of Calotropis gigantea (Asclepiadaceae) in experimental animals.

The roots of Calotropis gigantea have been used in leprosy, eczema, syphilis, elephantiasis, ulceration and cough in the Indian system of traditional medicine. The present communication evaluated its antipyretic activity by using yeast-induced and TAB (Typhoid) vaccine-induced pyrexia in rats and rabbits. In both yeast-induced and TAB vaccine-induced fever, the fever was significantly reduced and the body temperature was normalized by administration of 200 and 400 mg/kg dose intraperitoneally. Based on the results of the present study it can be concluded that the extract of C. gigantea has potential antipyretic activity against both yeast-induced and TAB vaccine-induced fever, indicating the possibility of developing C. gigantea as a cheaper and potent antipyretic agent.
