The characterisation of a further novel 1 a-hydroxycycloartane glycoside, mollic acid 3-p-~-xyloside, and of its genuine aglycone mollic acid is reported. Three new hydrolysis artifacts of the aglycone have been prepared and 13C .n.m.r. spectral data for these compounds are tabulated.We previously reported the isolation of mollic acid glucoside (1) a 1 ~-hydroxycycloart-24-en-30-oic acid 3-P-~-glucoside isolated from the acetone extract of Combretum molle leaves and showed that the acid hydrolysis of compound (1) in tetrahydrofuran (THF) gave the rearranged anhydro aglycone artifact (8).Subsequent investigations have led to the isolation of mollic acid (3), the genuine aglycone of (l), plus the related compound
