Abstract: | Ascorbic acid, thiamine, niacin, riboflavin, pantothenic acid and folic acid contents were determined in four different species ofPleurotus mushroom grown on wet chopped unfermented rice straw. The estimated values for the respective vitamins ranged from 92–144, 1.36–2.23, 60.6–73.3, 6.66–8.97, 21.1–33.3 mg and 1222–1412 µg per 100g mushrooms on dry weight basis. These vitamin values were comparable with those ofAgaricus bisporus, but were higher than those ofAuricularia, Lentinus andVolvariella. |
