摘要：

From the bark of Picramnia teapensis were isolated 7-hydroxycoumarin, emodin, the oxanthrone mayoside and three new compounds: two anthrone glycosides named picramniosides D and E and an oxanthrone glycoside named mayoside B. These new compounds were separated by recycling-HPLC and were identified on the basis of spectral data. CD was used to establish the absolute configuration of the new compounds.
