Abstract
Eight new natural products (four new cucurbitane aglycones, hemslepencins A–D (1–4), four new cucurbitane glucosides, hemslepensides F–I (5–8), along with seven known compounds (9–15), were isolated from the roots of Hemsleya pengxianensis. The structures of 1–8 were elucidated using IR, HRESIMS, and NMR. Compound 3 exhibited cytotoxic activity against the human cancer cell lines.
