No full textThe Aegle marmelos (L.) Correa (Bael), is indigenous to India and its leaves, bark, roots and fruit have been used for over 5000 years in the Indian traditional system of medicine like the Ayurveda, Naturopathy and in various folk medicine to treat various diseases including diabetes. This study was conducted to assess Knowledge, Practice and Use (KPU)of Aegle Marmelos (L.) Correa leaves among 20 Ayurvedic (AP) and Naturopathic practitioners (NP) in Vadodara city as well as desk reviews on various commercial formulations of Aegle Marmelos (L.) Correa (Bael) used in health and disease specially diabetes using internet Desk reviews were done using Pub Med and other web sources along with personal visits to various libraries across Gujarat state. For KPU, Purposive selection of AP (n=10) and NP (n=10) was done using snow ball sampling technique from Vadodara city in the form of key informant interviews based on their oral consent to share data among. Desk reviews revealed that Aegle Marmelos (L.) Correa leaves were being recognized as a remedy for the treatment of diabetes in both Ayurveda and Naturopathy. Many Ayurvedic formulations were available commercially as poly herbal formulations (PHF) rather than single drug in the market of various reputed brands which contained Aegle Marmelos (L.) Correa leaves in the form of various powder, tablets, capsules, etc. Naturopathy did not contain any commercial brands of Aegle Marmelos (L.) Correa leaves as it believes in fresh doses of the plant. KPU results revealed that AP used bael leaves for the treatment of diabetes and the dosage for the treatment ranged from 5-10g/day in various forms such as powder, decoction and dry extract in the form of capsules (1 capsule contains 0.5mg of extract which is equivalent to 5mg of leaf powder). NP also used bael leaves for the treatment of diabetes and the dosage ranged from 40-50 fresh leaves in the form of juice mixed with water to make a volume of around 100ml. Bael leaves were reported to be used by these practitioners as anti-diabetic agent. This information extracted warrants further clinical trials to prove the efficacy of the anti-diabetic properties of these leaves

No full textArtemisia, one of the larger genera in the family Asteraceae, comprises from 200 to more than 500 taxa at the specific or subspecific level. Artemisia herba-alba Asso (Shih) is grown in North Africa and certain parts of Asia and Middle East. It is one of the most widely used plants in the Algerian folk medicine. The antioxidant and free radical scavenging activities of the methanolic extracted materials were tested together with their antibacterial effects against isolated bacterial strains causing food poisoning. In summary, A. herba-alba Asso represent a good phenolic and flavonoid content (161, 64 mg/g and 16,83mg/g, respectively) in comparison with T. capitatus L which represent a phenolic content of 131, 48 mg/g and 14, 96 of flavonoid content. The results shows also that the methanolic extracts of the two plants possess a strong antioxidant (DPPH, FRAP assays) and antibacterial activities, which supports their ethnopharmacological use and A. herba alba represent the highest values (IC 50: 2, 35 mg/ml and OD 1, 13 at 700nm). Our results show the interest of A. herba-alba Asso and T. capitatus L, among other medicinal plants, in search of new chemo-preventive agents against biofilm and planktonic growth of food spoilage pathogens. Further studies are envisaged to target the most interesting molecules responsible for these activities. It is concluded that organic extracts from Artemisia herba alba Asso, exert strong antioxidant activities which are related to their polyphenol contents

In-vitro antioxidant, Xanthine oxidase-inhibitory and in-vivo Anti-inflammatory, analgesic, antipyretic activity of Onopordum acanthium
No full textOnopordum acanthium (Scotch thistle) belong to Asteraceae (Compositae). O. acanthium is a flowering biennial plant native to Europe and Western Asia with coarse spiny leaves 20-50 cm in width with conspicuous and spiny-winged stems. We have previously reported pro-apoptotic and cytotoxic effect of Onopordum acanthium crude extract against glioblastoma U-373 cells. The present study was designed to evaluate the cytotoxicity, antioxidant, xanthine oxidase inhibition, anti-inflammatory, analgesic, antipyretic activity of butanolic extract of Onopordum acanthium. Cytotoxicity of different solvent (methanolic, butanol, chloroform and petroleum ether) extract studied by brine shrimp lethality bioassay, total flavonoid and phenolic, antioxidant, xanthine oxidase inhibition activity was studied by in-vitro whereas anti- inflammation studied by carrageenan-induced paw edema model, antipyretic with 20 % brew yeast injection induced pyretic model, analgesic with 1 % acetic acid induced analgesic model investigated in in-vivo in wistar rats. Good antioxidant activity was found with IC50 = 134.4 µg/ml with considerable amount of total phenolic and flavonoid content. Xanthine oxidase inhibition effect was weak with IC50 = 572.9 µg/ml. Oral administration of O. Acanthium butanolic extract (OA) showed minimum lethality of brine shrimp nauplii henceforth OA butanolic phases was selected for further in-vivo studies. OA 200 and 400 mg/kg body weight decreased the oedema by 37.78 % and 40.52 %, respectively; standard aspirin 100 mg/kg decreased 42.62 % at 5th hour of Carrageenan injection. OA 200 and 400 mg/kg significantly decreased acetic acid-induced abdominal writhes when compared to standard aspirin. OA have shown dose and time dependent decrease in body temperature in yeast induced pyrexia, comparable to standard, aspirin. The present results demonstrate that OA has notable anti-inflammatory, antipyretic, analgesic activity related to presence of phenolic compounds as from literature it has been demonstrated that isolated compounds from aerial parts of Onopordum acanthium had strong activity in in-vitro assay

No full textAim of the study: The purpose of this study was to investigate the possibility of garlic extract as a feed additive to prevent and treat Salmonella infection. Methods: Garlic extracts were prepared from fresh crushed garlic and dissolved in different concentrations of ethanol. Garlic extract (Allium sativum) was analyzed by using gas chromatography-mass spectrometry (GC-MS). To examine biological activity, the antimicrobial activity test was carried out by minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against Salmonella typhimurium. Antioxidant activity of garlic extracts was examined by ABTS radical scavenging assay Results and discussion: In the GC-MS analysis, allyl trisulfide, 2-hydroxy-gamma-butyrolactone, 1, 3-dihydroxyacetne dimer, propanoic acid, 2-propone were confirmed as predominant components of garlic extract. the MIC was 10 mg/mL in all extracts. However, antioxidant effect was highest in 20 mg/mL of 100% ethanol garlic extract (82.1%). The amount of IC₅₀ (50% inhibitory concentration) was measured at 1.6 mg/mL. Conclusion: 75% ethanol garlic extract was the most efficient in considering the recovery rate, antimicrobial and antioxidant activities among the various extracts. Based on the above biological results, we could confirm this possibility as a feed additive for anti-salmonella infection
