Six new phenolic constituents, L-malic acid 2-O- (1), mucic acid 2-O- (5), mucic acid 1,4-lactone 2-O- (6), 5-O- (8), 3-O- (10), and 3,5-di-O- (11) gallates, were isolated from the fruit juice of Phyllanthus emblica together with their methyl esters (2-4, 7, 9), and their structures were determined
A new compound, mucic acid 3-O-gallate (1), was isolated from the fruit of Phyllanthus emblica L, together with 5 known compounds (2-6). Their structures were elucidated on the basis of spectroscopic analysis, including 1D and 2D NMR techniques, and by comparison with literature data.
The air-dried fruit hull of Phyllanthus emblica L. was extracted with 95% ethanol, and then the extract was partitioned by diethyl ether and ethyl acetate (EA). The EA fraction was then subjected to separation and purification using silica gel and Sephadex LH-20 column chromatography repeatedly to
Seven phenolic compounds, 1 - 7, including a new organic acid gallate, mucic acid 1-ethyl 6-methyl ester 2-O-gallate (7), were isolated from the MeOH extract of the fruits of Phyllanthus emblica L. (Euphorbiaceae). The structures were elucidated on the basis of extensive spectroscopic analysis and
Phyllanthus emblica L. fruits have long been used in Ayurvedic medicine for their many health benefits. In this study, we present P. emblica fruit crude extract and fractions' effects on the female reproductive system by assessing its estrogenic and gonadotropic activities. Results revealed that the
Phenolic compounds were extracted from dried emblic leafflower (Phyllanthus emblica L.) fruits with methanol and separated by Sephadex LH-20 column chromatography. The raw extracts and fractions were analyzed with HPLC coupled with diode array UV spectroscopy, electrospray ionization mass
Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disease, is closely associated with metabolic syndrome and refers to the accumulation of hepatic steatosis not due to excess alcohol consumption. Phyllanthus emblica L. is a rich source of gallic acid and many known medicinally
Fruits of emblic leafflower have been used as food and traditional medicine in Asia. A wide range of biological activities have been shown in modern research suggesting potential of the fruits as healthy food and raw material for bioactive ingredients of food. Hydrolyzable tannins are among the
