Abstract

Four new lanostane-type triterpenes, 24-ethyl-3β-methoxylanost-9(11)-en-25-ol (1), 3β-methoxy-24-methyl-enelanost-9(11)-en-25-ol (2), 3β-methoxy-25-methyl-24-methylenelanost-9(11)-en-21-ol (3) and 3β-methoxy-24-methyllanosta-9(11),25-dien-24-ol (4) together with three known triterpenes, betulinaldehyde, betulinic acid methyl ester, and ursaldehyde have been isolated from the methanol extract of the twigs of Diospyros discolor. The structures of those new compounds were elucidated by spectroscopic methods.
