[Research progress of Gastrodiae Rhizoma machining processing, composition analysis and in vivo metabolism].

Steaming method is a traditional processing method for Gastrodiae Rhizoma(GR). The current studies on the steaming method's mechanism of GR are mainly focused on facilitating softening slice, destroying the ß-glycosidic bond enzymes to reduce the decomposition of gastrodia glycosides (killing enzyme and protecting glycosides). The researches on the processing mechanism are still incomplete, while revealing and analyzing the active components in the body's metabolic process are important channels and new models to clarify the mechanism of traditional medicine processing. In order to provides a reference for the in-depth study of the processing mechanism of GR, we have reviewed the relevant literature at home and abroad in recent years and briefly summarized the processing, composition analysis and in vivo metabolism of GR in this study.

[A new category system of China nature reserves based on their attributes].

Based on the numeric attributes of 114 typical nature reserves in China, a new category system was established by using cluster analysis method. Compared with the China national category system of nature reserves, the new category system was simpler and more applicable. The 4 categories in the new system matched well to the categories I , II , IV, and V in IUCN category system, respectively. The new category system, characterized by the consistency of category criteria and scale, could avoid the deviation caused by subjective category to some degree, and provide a quantitative standard for the classification of nature reserves in China.
