蜂猴(Nycticebus coucang)和树鼩(Tupaia belangeri chinensis)mt DNA 10种限制酶物理图谱

本研究用10种限制性内切酶对蜂猴和树鼩肝脏线粒体DNA进行了分析. 蜂猴线粒体DNA, BglⅠHind Ⅲ、PstⅠ、SalⅠ和XhoⅠ均各只1个切点、EcoRⅠ、BglⅡ和Pvu Ⅱ各有2切点, BamHⅠ和 EcoRⅤ 分别有3个切点. 对于树鼩线粒体 DNA, BglⅡ、Hind Ⅲ、PstⅠ、SalⅠ和 XhoⅠ均只1个切点, BamHⅠBglⅠ和 PvuⅡ 分别有2个切点, EcoRⅠ 有3个切点, EcoRⅤ有4个切点. 根据单酶和双酶解片段的数目和分子量, 建立了蜂猴和树鼩线粒体 DNA 的物理图谱。

Anti-HIV-1 activities of extracts from the medicinal plant Rhus chinensis

Rhus chinensis, a species used in folk medicine by Chinese native people, the anti-HIV-1 activities of the petroleum ether, ethyl acetate, butanol and aqueous extract of Rhus chinensis, named as RC-1, RC-2, RC-3 and RC-4, respectively, was evaluated. The

Anti-HIV-1 activities of compounds isolated from the medicinal plant Rhus chinensis

Aim of the study: Previously, we reported that the petroleum ether fraction, RC-1, and EtOAc fraction, RC-2, of the medicinal plant Rhus chinensis showed potent anti-HIV-1 activities. To address anti-HIV-1 constituents of RC-1 and RC-2, 17 compounds were
