ABSTRACT
Here we report a new polyhydroxylated triterpene, 2β,6β,21α-trihydroxyfriedelan-3-one (4) isolated from the root and stem bark of Dichapetalum albidum A. Chev (Dichapetalaceae), along with six known triterpenoids (1-3, 5, 6, 8), sitosterol-3β-O-D-glucopyranoside (9), dipeptide (7), tyramine derivative coumaric acid (10). Friedelan-3-one (2) showed an antimicrobial activity (IC50) 11.40 μg/mL against Bacillus cereus, while friedelan-3α-ol (1) gave IC50 13.07 Staphylococcus aureus ampicillin reference standard 19.52 0.30 respectively. 3β-Acetyl tormentic (5) 12.50 Trypanosoma brucei sitosterol-3β-O-d-glucopyranoside (9) 5.06 Leishmania donovani respective standards 5.02 for suramin 0.27 amphotericin B. Molecular docking compounds on enzyme glucose-6-phosphate dehydrogenase (G6PDH) suggested 3β-acetyl as plausible inhibitors in accordance experimental biological results observed.
