“…Antioxidant therapy has gained an utmost importance in the treatment of several metabolic disorders, where free radicals are implicated (Halliwell, 1997;Shrestha et al, 2013;Shrestha et al, 2014;Eshwarappa et al, 2014;. Globally, a large number of researchers have aimed at identifying medicinal plants for their potent antioxidant properties to be implicated in metabolic disorders (Auddy et al, 2003;Shrestha et al, 2013;Shrestha et al, 2014;Eshwarappa et al, 2014;.…”

Background. Pistacia integerrima (P. integerrina) insect galls are widely used in ayurveda and siddha system of medicine as karkatasringi. The use of leaf galls as a rejuvenator may be attributed to antioxidant property, however there is less scientifi c evidence. Therefore, the aim of this study was to evaluate the chemical composition and the antioxidant potential of leaf gall extracts (aqueous and ethanol) of P. integerrina, which is extensively used in the preparation of traditional medications. Material and methods. The antioxidant activities of aqueous and ethanolic leaf gall extracts were examined using diphenylpicrylhydrazyl (DPPH), hydroxyl scavenging and ferric reducing power (FRAP) methods. Results. The presences of phenolics, tannins, phytosterols, triterpenoids, saponins, fl avonoids and reducing sugars were identifi ed in both the extracts. In comparison to the aqueous extract, the ethanolic extract had the highest total phenolic and fl avonoid content at 234 ±2.4 mg of GAE/g d.w. and 95.5 ±3.2 mg of QUE/g d.w., respectively. This higher content of total phenolics and fl avonoids found in the ethanolic extract was directly associated with higher antioxidant activity. Conclusion. This study demonstrates the poetnet antioxidant activities of P. integerrima leaf gall extracts. Further, there was a strong association between the higher antioxidant activities with that of higher total phenolic and fl avonoid content in the ethanolic leaf gall extracts of P. integerrima. The results encourage the use of P. integerrima leaf gall extracts for medicinal health, functional food and nutraceuticals applications, due to their antioxidant properties. Future work will be interesting to learn the chemical composition and better understand the mechanism of action of the antioxidants present in the extract for development as a drug for therapeutic application.

“…The galls are reported to contain tannins, gallic acid, syringic acid and ellagic acid 5 . Most of the earlier studies on Q. infectoria were on the pharmacognostic, pharmacological and biological studies including anti-inflammatory, antidiabetic, larvicidal, antiulcerogenic, gastroprotective, antibacterial and antiviral activities 5,6 . However, there are no reports on the quantitative estimation of gallic acid from the galls.…”

ABSTRACT:The galls of Quercus infectoria Oliv. (Family: Fagaceae) are commonly known as "Manjakani" by Malaysian community. It is one of the most popular traditional medicines used by the females to help regression of prolapsed uterus. The aim of this study was to perform the proximate analysis and quantitative estimation of gallic acid in the methanol extract of locally available galls of Q. infectoria using HPTLC. The gall powder was subjected to the quantitative determination of moisture content, ash and extractive values according British Pharmacopoeia. Preliminary phytochemical studies were performed on different extracts to find out the nature of phytoconstituents they contain. Quantitative estimation of gallic acid in the methanol extract was assessed through denstiometric scanning using a TLC Scanner 3 (Camag, Switzerland) with win CATS software. The results of the preliminary phytochemical screening of various extracts revealed presence of steroids, triterpenoids, saponins, flavonoids, tannins and phenolic compounds, carbohydrates, gums and mucilages respectively in the galls. Amount of of gallic acid in the sample was found to be 0.218 ± 0.0011% w/w. The present method was validated for linearity, accuracy, precision, and specificity with reference to ICH guidelines. The developed method is capable of quantifying gallic acid in locally available samples of Q. infectoria.

A simple and rapid high‐performance thin‐layer chromatographic method for quantification of gallic acid and ellagic acid in dried fruits of Terminalia chebula, Phyllanthus emblica, and Quercus infectoria has been developed. The chromatographic development was carried out on precoated silica gel 60 F254 plates in a mixture of toluene:ethyl acetate:chloroform:formic acid (4:8:1:3 v/v/v/v). The plate was scanned densitometrically at a wavelength of 280 nm. The retention factor value of gallic acid and ellagic acid was found to be 0.63 ± 0.2 and 0.53 ± 0.1, respectively. The developed method was validated in terms of linearity, precision, accuracy, sensitivity, robustness, specificity and stability as per the international conference of harmonization guidelines. The method showed good linear relationship over a range of 100–600 ng/band (gallic acid) and 100–500 ng/band (ellagic acid) with a regression coefficient (r2) of 0.997 (gallic acid) and 0.996 (ellagic acid). The method showed high accuracy (99.65%–100.85%). The percentage relative standard deviation of intra‐day and inter‐day precision studies was not more than 2%. The method is highly robust and has displayed high specificity. The developed method is new, simple, and accurate and can be successfully employed in routine analysis of raw materials and formulations containing gallic acid and ellagic acid.
