不同生长周期的罗汉果鲜果中甜甙V和总黄酮含量变化规律研究

通过使用HPLC法对不同生长周期的罗汉果鲜果中罗汉果甜甙V和总黄酮的含量进行测定,总结出罗汉果中罗汉果甜甙V和总黄酮含量的变化规律,并对二者进行比较研究,结果表明坐果50d后,罗汉果甜甙Ⅴ的增加比较快,80d后,罗汉果甜甙Ⅴ的含量趋于稳定;随着生长周期的增加,罗汉果总黄酮的含量增加,40～50d中增长最快,坐果约50d后达到最高值,从60d开始总黄酮的含量迅速下降到20d水平,然后趋于稳定。

Study on the variation of mogroside V and flavone glycoside in Siraitia grosvenorii fresh-fruits in different growth periods

The content of mogroside V and flavone glycoside in Siraitia grosvenorii with different growth periods by was analyaed HPLC,and the law of the variation in the contents of mogroside V and flavone glycoside was summariaed. Comparative study of them was also taken. The result shows that the content of mogroside V increases rapidly after 50 days and gets stability after 80 days. The content of flavone glycoside increase rapidly from the 40th day to the 50th day, and reaches the highest after about 50 days. It declines to the level as the 20th day after 60 days and then gets stability.
