Nine compounds were isolated from the fruits of Hemsleya graciliflora. IIThey were identified as- 25-acetate of dihydrocucurbitacin F(I), dihydrocucurbitacin F(II), cucurbitacin F-25-acetate(III), sitostery1-3-O-beta-D-glucoside-6'-O-palmitate(IV), daucosterol(V), beta-sitosterol(VI), palmitic
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,
Seven new cucurbitane glucosides, hemslepensides J-P (1-7), and two known compounds, 16,25-O-diacetyl-cucurbitane F (8) and 25-O-acetyl-23,24-dihydrocucurbitacin F (9), were isolated from the tubers of Hemsleya pengxianensis var. jinfushanensis. The structures of 1-7 were elucidated using infrared
