Analysis of Vitamin B1 and B2 Content of 9 Edible Wild Mushrooms in Yunnan Province

分析化学进展 Abstract Using 9 common edible wild mushrooms in Yunnan as raw materials, including Cantharellus ciba-rius Fr, Catathelasma ventricosum , Russula virescens (Schaeff.) Fr, Russula virescens , Ramaria bo-trytoides , Boletus speciosus , Boletus brunneissimus , Boletus luridus , and Boletus riegius Krombh. Referring to the methods and conditions of GB 5009.84-2016 and GB 5009.85-2016, the content of vitamin B1 and B2 in 9 edible wild mushrooms was determined, the vitamin B1 and B2 content between fresh and dried wild mushrooms was compared, and the content of vitamin B1 and B2 in wild mushrooms stored at the same temperature for different cycles was analyzed. The results showed that all 9 edible wild mushrooms contained vitamin B1 and B2, but the content of vitamin B1 and B2 in dried wild mushrooms was much higher than that of fresh wild mushrooms, which was 2~10 times higher than that of fresh wild mushrooms. Vitamin B1 in wild mushrooms stored at the same temperature for different cycles will degrade as the storage cycle increases, while vitamin B2 is very stable and not easily oxidized. This provides a theoretical basis for the further development and utilization of wild edible mushroom resources.
