Introduction:Myrica esculenta Buch.-Ham. (Myricaceae) is commonly known as Box Berry, Kaiphal, and Katphala in Ayurveda. As per the Ayurvedic literature the palnt is used for variety of diseases and disorders. Method: The present study deals with the pharmacognostical standardization, HPTLC analysis and antioxidant activity of methanolict extracts of the leaves of M. esculenta. The plant showed high phenolic and flavonoid content. In-vitro antioxidant study of dried leaves of Myrica esculanta was performed using methanolic extract. Results: Antioxidant activity of M. esculenta methanolic extract showed the least IC 50 value of 60 ± 1.15 μg/ml. Standard ascorbic acid showed an IC 50 value of 2.03 ± 0.06 μg/ml. The calibration curve of Gallic acid showed r 2 of 0.949 and R f of gallic acid was found to be 0.44 ± 0.006. Quantification of gallic acid in the samples of leaves of M. esculenta has been performed and the gallic acid was found to be 0.056%. Conclusion: The presence of gallic acid has not yet been reported and quantified in this species which may be utilized for the proper standardization of the drug. The present study showed new natural antioxidant that can replace the synthetic ones to be used in foods and cosmetics. Key words: Antioxidant, DPPH, Myrica Esculenta, Gallic Acid, HPTLC. anti-microbial, 9,10 anxiolytic, 11 while the fruits are known for their anti-oxidant properties and Antimicrobial nature 12,13 The whole plant is an effective chemo preventive agent in skin. Prashant14 Conventionally, foremost tribal communities of Uttarakhand exploit the bark revealing its ethonobotanical importance. It is well known to be effective in chronic cough, asthma and ear ache. When the bark powder is applied externally, it heals chronic and malignant ulcers, and also to intoxicate the fishes. 15 In Ayurveda, the plant is known to have antispasmodic, antiinflammatory, analgesic properties. 16 The antibacterial activity of fruit and bark of the plant has been performed earlier.17 Till now there are so many Synthetic antioxidants are commercially available but quite unsafe, and their toxicity is a distressing trouble. 18 The natural antioxidants, mainly phenolics and flavonoids, are safe, having prominent biological activity, so the current focuses on natural antioxidants from natural plants. Some Reagents used were from Merk (Germany) and standard gallic acid was procured from Sigma-Aldrich (Steinheim). Chromatographic ConditionsChromatography was performed on Merk HPTLC pre coated silica gel 60GF254 (20 X 20 cm) plates. Methano lic solutions of samples and standard compound gallic acid of known concentrations were applied to the layers as 6 mm-wide bands positioned 15 mm from the bot tom and 15 mm from side of the plate, using Camag Linomat V automated TLC applicator with the nitrogen flow providing a delivery speed of 150 nl/s from the application syringe. These conditions were kept constant throughout the analysis of samples. Detection and Quantification of Gallic acidFollowing sample application, l...
Current study discussing the ethnobotanical importance of the different part of the plant Dalbergia sissoo its pharmacological activity and various formulation. Nature is like a treasure of medicine. From last thousands year nature give us several type of medicines which we use for the treatment of different type of diseases and valetudinarism. Dalbergia sissoo is one the most crucial/significant plant with full of medicinal attribute. Dalbergia sissoo (Fabaceae) has reported to possess different type pharmacological activity such as antinociceptive activity, anti-coagulant activity, antibacterial activity, anti-inflammatory activity, memory enhancing activity, antiulcer activity, nephro-protective activity, anti-spermatogenic activity, analgesic activity, antipyretic activity, antitermitic activity, antilithiatic activity, antidiabetic activity, anthelmintic activity, immunomodulation activity and so on. This study divulging the medicinal important and all pharmacological action of the different part of the plant Dalbergia sissoo.
