Five new triterpenoid saponin glycosides, trichocucumerisides A–E (1–5), together with eleven known compounds (6–16) were isolated from Trichosanthes cucumerina fruit fibers. The structures of the new compounds were elucidated by detailed analysis of NMR and mass spectroscopic data as well as chemical reactions. The anti-inflammatory study against nitric oxide (NO) production in lipopolysaccharide
从Trichosanthes cucumerina果实纤维中分离出5 种新的三萜皂甙苷 A-E ( 1-5 ) 以及 11 种已知化合物 ( 6-16 )。通过对 NMR 和质谱数据以及化学反应的详细分析,阐明了新化合物的结构。对脂多糖 (LPS) 刺激的 RAW264.7 细胞中一氧化氮 (NO) 产生的抗炎研究表明,化合物7和9表现出更强的 NO 抑制活性,IC 50值分别为 3.0 和 2.7 μM,与阳性对照塞来昔布和氨基胍(IC 50值分别为 75.7 和 75.0 μM)。化合物7和9的选择性指数 (SI) 也比阳性参考物高约 3-4 倍。
