title: [Classification and distribution analysis of components in Glycyrrhiza using licorice compounds database].
abstract: In order to study the chemical components of licorice deeply and systematically, a licorice compounds database was established after the comprehensive summary of the compounds in Glycyrrhiza. The database was used to classify the licorice components anew in order to statistically analyze the distribution of each type of compounds and the compounds in the medical Glycyrrhiza plants. The results indicated that 422 compounds had been reported in Glycyrrhiza so far, and they could be categorized into 5 classes as flavoids, coumarins, triterpenoids, stilbenoids, and some others. Up to now, 170 compounds were isolated from G. uralensis, 134 compounds from G. glabra, 52 compunds from G. inflata, and 31 from G. yunnanensis. It is the first time to add categorization "stilbenoids", and "dibenzoylmethanes" classified as chalcones. In the meantime, the database is supposed to be convenient for further study.
