Five new labdane diterpenes from Aster oharai.
Five new labdane diterpenes (1-5) together with seven known diterpenes have been isolated from a methanol extract of the aerial parts of Aster oharai. Five new structures were determined as 7alpha-hydroperoxylabda-8(17),14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (1), 7alpha-hydroperoxylabda-8,14-dien-13(R)-ol-4-O-acetyl-alpha-L-6-deoxyidopyranoside (2), labda-7,14-dien-13(R)-ol-4-...
