Sources of varieties and quality of circular Fructus Ligustri Lucidi.

This study aimed to trace sources and quantitatively analyze the specnuezhenide content of circular Fructus Ligustri Lucidi for clinical use. Different specifications of Fructus Ligustri Lucidi were identified using DNA barcoding technology and the specnuezhenide content was analyzed by High Performance Liquid Chromatography (HPLC). The ITS sequence of circular Fructus Ligustri Lucidi was identical to that of standard privet, which was determined through botanical identification.

[Effect of exogenous brassinolide on morphological characters and contents of seven chemical constituents of Glycyrrhiza uralensis].

The transplants of the two-year-old Glycyrrhiza uralensis were subjected to four concentration of brassinolide (BR 0.1, 0.4, 0.

[Mechanism of genuineness of Glycyrrhiza uralensis based on SNP of β-Amyrin synthase gene].

β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.

[A new herbs traceability method based on DNA barcoding-origin-morphology analysis--an example from an adulterant of 'Heiguogouqi'].

The fruit of Lycium ruthenicum is a common folk medicine in China. Now it is popular for its antioxidative effect and other medical functions. The adulterants of the herb confuse consumers.
