[Biological research of color and quality evaluation in "quality discrimination by character" of Chinese medicine].

In the theories of empirical identification of "arguments on quality" and "five elephants and seven originals", color is regarded as one of the important indicators in the quality evaluation of Chinese medicine. The color of medicinal material including the surface color, the internal color, and the color after processing is caused by the pigment in the cells, which is a characteristic of the "optimal shape". Most pigments have a wide range of pharmacological activities such as anti-oxidation, anti-tumor, anti-atherosclerosis, prevention of coronary heart disease, protection of cardiovascular function, enhancement of immunity, etc.

[Analysis of bacterial community structure and diversity during mountain-agarwood formation].

As an important substitute for agarwood, mountain-agarwood, belonging to the family Oleaceae, comes from the root, stem and thick branch of Syringa pinnatifolia, which has a wide range of application in Inner Mongolia, China. It has good clinical efficacy in the use of cardiovascular diseases. However, the formation speed of mountain-agarwood is extremely slow, and its cultivated seedlings have low resin content.

[Allele-specific PCR to identification of Achyranthis Bidentatae Radix and Cyathulae Radix formula granules].

To establish a robust and accuracy molecular method to identify Achyranthis Bidentatae Radix and Cyathulae Radix formula granules. ITS sequences of Achyranthes bidentata and Cyathula officinalis were aligned, specific SNPs (single nucleotide polymorphisms) were excavated, specific primers were designed and allele-specific PCR method was established. The genomic DNA was successfully extracted from the herbal medicine and its formula granules by using an improved CTAB (cetyltrimethyl ammonium bromide) method and then performed PCR with the designed primers.
