Ten previously undescribed glucosyloxybenzyl succinate derivatives, pleionosides A-J, and fifteen known compounds were isolated from the pseudobulbs of Pleione bulbocodioides (Franch.) Rolfe. Their structures were elucidated by a combination of MS and NMR data, physical and chemical methods and a comparison with known compounds. Furthermore, three compounds exhibited potent hepatoprotective activity against N-acetyl-p-aminophenol (APAP)-induced HepG2 cell damage in in vitro assays, with cell survival rates of 31.89%, 31.52% and 31.97% at 10 μM. Four compounds exhibited moderate antioxidant activity with increasing viability at 10 μM of 36.1%, 45.0%, 25.5% and 20.7%.
从 Pleione bulbocodioides(Franch.) Rolfe 的假鳞茎中分离得到了 10 种以前未描述的葡萄糖氧基苄基琥珀酸酯衍生物,即 pleionosides A-J,以及 15 种已知化合物。通过 MS 和 NMR 数据、物理化学方法以及与已知化合物的比较,确定了它们的结构。此外,三种化合物在体外试验中对 N-乙酰对氨基苯酚(APAP)诱导的 HepG2 细胞损伤表现出很强的保肝活性,在 10μM 时细胞存活率分别为 31.89%、31.52%和 31.97%。四种化合物表现出中等的抗氧化活性,在 10μM 时细胞活力分别增加了 36.1%、45.0%、25.5%和 20.7%。
