To analyze, identify and quantitatively determine active components and nutrients in Meizhou Shatian pomelo flowers.
Ultra performance liquid chromatography-quadrupole/exactive-orbitrap high resolution mass spectrometry (UPLC-QE-Orbitrap-HRMS) combined with workstation TraceFinder 5.0 and its Chinese medicine database were used to analyze non-volatile components of Shatian pomelo flower. Active compounds and nutrients in pomelo flowers were determined by other various detection techniques.
A total of 51 kinds of non-volatile active components were identified in pomelo flowers, including 19 kinds of flavonoids, 11 kinds of coumarins, 8 kinds of terpenoids, 3 kinds of organic acids, 2 kinds of aldehydes, 2 kinds of amino acids, 2 kinds of nucleosides, 1 kind of phenol, 1 kind of alkaloid and 2 kinds of other compounds. Types and content of flavonoids in pomelo flowers were rich. Naringin, total saponins, fat, protein, dietary fiber, carbohydrate, 5 kinds of vitamins and 10 kinds of nutrient elements in dried pomelo flowers were determined quantitatively in this study. The content of naringin was high to 13.9 g/100 g. The content of saponins, vitamin C and vitamin E were relatively high.It also contained a variety of trace elements needed by human body.
Pomelo flowers are rich in active components and nutrients. This study provides a scientific basis for pomelo flowers related to the formulation of quality standards, the comprehensive utilization of resources and product development.
