Two New Glycosides from Conyza bonariensis [PDF]

Natural Product Communications, 2010
Studies on Conyza bonariensis (L.) Cronq. led to the isolation of two new glycosides trivially named as erigeside E and F (1–2), along with two new source compounds; benzyl-β-D-glucopyranoside (3) and 2-phenylethyl-β-D-glucopyranoside (4). Compounds 1, 3, and 4 are aromatic glycosides, while compound 2 is an alkyl glycoside.
