从竹节参的乙醇提取物分离得到了12个化合物,通过MS和NMR等方法鉴定为:竹节参皂苷IVa(1),椽木皂苷A(2),竹节参皂苷Ib(3),竹节参皂苷V(4),尿嘧啶(5),胸嘧啶(6),尿苷(7),鸟苷(8),胸苷(9),腺苷(10),肌苷(11),胞苷(12),其中5—12为首次从该植物中分离。
Twelve known compounds were isolated from the roots of Panax japonicus. On the basis of MS and NMR analysis,these compounds were determined as chikusetsusaponin 1V a (1), araloside A (2), chikusetsusaponin I b (3), chikuset-susaponin V (4), uracil (5), thymine (6), uridine (7), guanosine (8), thymidine (9), adenosine ( 10),ino- sine (11) ,cytidine (12), among which eight compounds (5-12) were obtained from this plant for the first time.
