以人参须为发酵基质进行赤芝双向固态发酵,测定发酵过程中人参皂苷Rb2和Rb3的含量,分析固态发酵对其影响。发酵作用使基质中Rb2和Rb3含量发生显著变化,但2种皂苷含量变化不同。Rb2在发酵初期和发酵后期都出现含量先升高后降低的过程,Rb3仅在发酵初期含量先升高后降低,发酵结束时基质中未检测到2种皂苷。 Ginseng should be used as the fermentation substrate for two-way solid-state fermentation of Ganoderma lucidum, ginsenosides Rb2 and Rb3 content in the fermentation process was measured to analyze the impact of solid-state fermentation. Fermentation led to a significant change in the contents of Rb2 and Rb3 in the matrix, but the content of the two saponins varied. The content of Rb2 increased firstly and then decreased in the early fermentation stage and the late fermentation stage. The content of Rb3 increased first and then decreased at the initial fermentation stage. No two saponins were detected in the matrix at the end of the fermentation.
