Abstract

Abstract:

Based on the results of single factor, orthogonal test design was adopted to optimize the extraction technology of total flavonoids in Camellia nitidssima leaves. With rutin as reference material, the dynamic change law of content of total flavonoids in Camellia nitidssima leave was analyzed using spectrophotometry. The results showed that the optimal extraction conditions are: using 70% ethanol as extractant, ratio of material to solution 1:50 (W/V), extraction time 2.0 h, extraction temperature 70 ℃. The content of total flavonoids in Camellia nitidssima increases fluctuatingly from January to October, reaching the highest at October.

Key words: Camellia nitidssima, total flavonoids, extraction technology, dynamic change
