Five triterpenoids were isolated and their structures were identified to be cauloside C (1),akebiasaponin D (2),akebiasaponin F (3),ursolic acid (4) and hederagenin (5).

分离鉴定了5个三萜类化:岩仙C(1)、木D(2)、木F(3)、熊果酸(4)和常春藤(5)。

The catechin, ursolic were determined by HPLC.The polysaccharide and tannide were determined by sulphoacid-phenol and complexometric titration methods respectively.

用HPLC法测定儿茶素和熊果酸，硫酸-苯酚法测定多糖，络滴定法测定鞣质的含量。
