Analysis of the structure of tomato fruit anthocyanins

Recently, the functional gene innovation team of the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Sciences analyzed the structure and main modification types of anthocyanins in tomato fruits through the study of anthocyanins in purple fruit tomatoes, and discovered 4 new types of flowers in tomato fruits. The cyanidin composition has laid a theoretical foundation for analyzing the synthesis and metabolism of anthocyanin in tomato fruit.

According to researcher Cui Xia, anthocyanins are a class of antioxidants that are beneficial to human health and have certain medicinal value. In plants, anthocyanins can improve the ability of plants to resist adversity. Anthocyanins in plants mainly include derivatives of cyanidin, pelargonin, delphinium, paeoniflorin, petunidin, and malvadin. The structural analysis of anthocyanins is of great significance to the study of their metabolic pathways. Tomato is a very popular fruit in the market. As a highly antioxidant vegetable, purple tomato is favored by the market, but the analysis of its anthocyanin structure has been lacking. This study established a rapid quantitative method for fruit anthocyanins, and detected 12 anthocyanins in purple fruit tomatoes. It was found that petunidin derivatives and malvacin derivatives were the main components of anthocyanins in the peel. Four new anthocyanin components in tomato.

The research was funded by the National Key Research and Development Program, the basic scientific research business expenses of central public welfare research institutes and the scientific and technological innovation project of the Chinese Academy of Agricultural Sciences.
