Conservation and threatened status of plant species with extremely small populations in the karst region of southeastern Yunnan, China.

The southeastern Yunnan is one of the most typical areas in China with karst landforms. The rich variety of vegetation types and plant diversity means that threatened status are also synchronized. Over the past 20 years, the comprehensive conservation team for plant species with extremely small populations (PSESP) has conducted in-depth field surveys in the region, combining relevant literature and conservation projects to compile a list of PSESP which including conservation and endangered status, conservation actions, and scientific research.

Pharmacokinetics of geniposide by monoclonal antibody-based icELISA in mice after oral administration of Huanglian-Jiedu-Tang.

Geniposide, Geniposide, the main active component in extracts of Gardenia jasminoides ELLIS., is one of the main components of Huanglian-Jiedu-Tang (HJT). This study aimed to validate an indirect competitive enzyme-linked immunosorbent assay (icELISA) based on monoclonal antibodies (mAb) against geniposide (anti-geniposide mAb), which was developed by our lab, and apply the assay to study the pharmacokinetics of geniposide in HJT in mice.
