从茄科(solanum myriacanthumDunal)果实中分离到一种新的胆甾烷型甾体苷solamyriaside A(1),以及两种已知的甾体苷solaviaside A(2)和aculeatiside A(3),以及三种已知的甾体生物碱苷solamargine(4)、hasasianine(5)和solasonine(6),这是首次从该植物中分离到。根据光谱数据和化学证据,确定1为3-O-α- l-鼠李糖吡喃基-(1→2)- o -[α- l-鼠李糖吡喃基-(1→4)]-β- d -葡萄糖吡喃基- 22r, 25r -胆-5-烯-3β,16α,22,26-四醇26-O-β- d -葡萄糖吡喃苷。检测了1 -6对HL-60人早幼粒细胞白血病细胞的细胞毒活性。化合物4 ~ 6具有细胞毒活性。其中4种活性最强,ic50值为4.64±0.17 μM,与阳性对照顺铂的活性相近。
A new cholestane-type steroidal glycoside, solamyriaside A (1), was isolated from the fruits ofSolanum myriacanthumDunal (Solanaceae), along with two known steroidal glycosides, namely, solaviaside A (2) and aculeatiside A (3), and three known steroidal alkaloid glycosides, namely, solamargine (4), khasianine (5) and solasonine (6), which were isolated for the first time from this plant. Based on spectroscopic data as well as chemical evidence,1was determined to be 3-O-α-L-rhamnopyranosyl-(1→2)-O-[α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranosyl-22R,25R-cholest-5-ene-3β,16α,22,26-tetraol 26-O-β-D-glucopyranoside. The cytotoxic activity of1–6against HL-60 human promyelocytic leukaemia cells was examined. Compounds4–6showed cytotoxic activity. Among them,4exhibited the strongest activity with an IC50value of 4.64 ± 0.17 μM, similar to the activity of cisplatin, a positive control.
