Occurrence of pieroside C, a grayanotox-9-ene derivative, in Pieris japonica.
摘要:
A new diterpene glycoside, pieroside C, has been isolated together with grayanotoxin-VII and -XVIII from Pieris japonica D. DON (Ericaceae). Its structure was determined by chemical and spectroscopic means to be 3-O-(B-D-glucopyranosyl)-3, 5, 6, 16-tetrahydroxygrayanotox-9-ene. This is the first report of a grayanotox-9-ene derivative occurring in nature.
