GRAPHICAL ABSTRACT
ABSTRACT
Phytochemical study of Adinandra hainanensis stems led to the isolation of a new triterpene lupan-3β,20-dihydroxy-28-carbaldehyde (1) and eleven known compounds 2-12. The stems of A. hainanensis was rich in lupane-type triterpenes, especially betulinic acid (9) was abundant (around 0.45% w/w). The isolated triterpenes, including new compound 1 showed strong α-glucosidase inhibitory activity with IC50 values ranging of 2.27 ± 0.05 μg/mL to 12.25 ± 0.36 μg/mL. In the cytotoxic evaluation, betulinic acid, the major component, showed good cytotoxic activity against all tested cancer cell lines while new compound 1 was weakly active.
