Abstract:
OBJECTIVETo investigate the chemical constituents of Tibetan medicine Phyllanthus emblica.
METHODVarious chromatographic techniques were employed for isolation and purification of the constituents, and the structures were elucidated by chemical and spectral analyses.
RESULT11 compounds were isolated and identified as gallic acid (I), ellagic acid (II), 1-O-galloyl-beta-D-glucose (III), 3,6-di-O-galloyl-D-glucose (IV), chebulinic acid (V), quercetin (VI), chebulagic acid (VII), corilagin (VIII), 3-ethylgallic acid (3-ethoxy-4,5-dihydroxy-benzoic acid, IX), isostrictiniin (X), 1,6-di-O-galloyl-beta-D-glucose (XI).
CONCLUSION3-Ethylgallic acid (3-ethoxy-4,5-dihydroxy-benzoic acid) is a novel compound, and isostrictiniin was found from P. emblica for the first time.
