Abstract/Summary

Ficus ampelas, a Philippine medicinal plant also known as upling gubat, was studied for its chemical constituents. The dichloromethane extract of the air-dried stems of F. ampelas afforded a 2:1 mixture of oleanolic acid (1) and ursolic acid (2). The dichloromethane extract of the air-dried leaves of F. ampelas yielded butyrospermol cinnamate (3) and lutein (4) in separate isolates. The structures of 1-3 were elucidated by NMR spectroscopy, particularly 1HNMR, 13CNMR, COSY, HSQC, and HMBC, and their 1HNMR and 13C NMR data were compared with those reported in the literature42, 43. The structure of 4 was identified by comparison of its 1HNMR data with those reported in the literature49. The four compounds are reported to have a range of biological activities based on literature search.
