Main Article Content
Abstract
Polygonum posumbu Buch.-Ham. ex D. Don is a weed that grows in moist soils along forests, rivers. According to traditional knowledge, this plant has been used to treat dysentery, gastroenteritis, diarrhea, rheumatism. In the study on chemical constituents using chromatographic methods, 4 isolated compounds have been obtained from the ethyl acetate fraction of P. posumbu, namely gallic acid, myricetin, distichin and quercitrin. Among them, myricetin, distichin and quercitrin have been isolated for the first time from P. posumbu and distichin has been isolated for the first time in the genus Polygonum
