目的对蓝萼香茶菜Rabdosia japonica var.glaucocalyx根化学成分进行研究。方法采用多种色谱方法进行分离纯化,运用多种谱学方法鉴定化合物的结构。结果从蓝萼香茶菜根70%乙醇提取物中分离得到2个松香烷二萜苷类化合物,分别鉴定为蓝萼香茶菜苷(1)和内折香茶菜苷A(2)。结论化合物1为新的松香烷二萜苷类化合物,命名为蓝萼香茶菜苷,化合物2为首次从该植物中分离得到。 Aim To study the chemical constituents of Rabdosia japonica var.glaucocalyx. Methods A variety of chromatographic methods were used to separate and purify the compounds. The structures of the compounds were identified by a variety of spectroscopic methods. Results Two rosin diterpene glycosides were isolated from 70% ethanol extract of Camellia oleifera, which were identified as calyx catechin (1) and penicillin A (2), respectively. Conclusions Compound 1 is a new rosin diterpene glycoside named as calyx kaempferide. Compound 2 was isolated from this plant for the first time.
