[求助] 【求助文章翻译】翻译天然药化论文的这一段

Cynomorium plants contain large amount of flavonoids with flavan-3-ols being the major ones. Other sub-flavonoid
types in Cynomorium plants are flavones, flavonols, and flavanones. From the aqueous extract of the stems of C. songaricum,
catechin, procyanidin B-1 , procyanidin B-6 , flavan-3-ol trimers, flavan-3-ol tetramers, flavan-3-ol pentamers, and flavan-3-ol polymers (condensed tannins) were obtained. Thiolytic degradation of the flavan-3-ol polymers yielded benzylthioepicatechin, indicating that the extender flavan unit of the condensed tannin is mainly epicatechin . The flavan-3-ol polymers showed inhibitory activity against HIV PR with the activity increased as the molecular weight increased. Using capillary electrophoresis with amperometric detection, epicatechin and catechin were detected in all of the seven Cynomorium samples collected in different areas

Two anthocyanin pigments  were isolated from the flowering tops of C. coccineum. Cyanidin 3-O-glucoside was identified to be the major pigment (92%), while cyanidin 3-O-rhamnosylglucoside  was identified to be the minor one (8%) . Besides the above mentioned flavan-3-ols and anthocyanins, compounds 20-27 (Fig. 5) of other flavonoid sub-types were isolated or detected in C. songaricum.

植物锁阳含有大量的黄酮类化合物,以黄烷-3-醇类为主。在植物锁阳中其它的黄酮类化合物有黄酮、黄酮醇和二氢黄酮。从锁阳的水提液中得到儿茶素、原花青素B-1、原花青素B-6、黄烷-3-醇三聚体、黄烷-3-醇四聚体、黄烷-3-醇五聚体和黄烷-3-醇多聚体。硫解降级黄烷-3-醇多聚体产生苯甲基硫表儿茶素,表明冷凝的单宁酸黄烷聚合体的混合物主要是表儿茶素。
