Abstract

The absorbing curve of hypocrellin A and effect of alcohol concentrations , immersed time , stomata granularities , alcohol dosages on the extraetion of hypocrellin A were studied in the paper .The results showed that the best scheme of determining the content of hypocrellin A in Shiraia bambusicola stomata was 1 g of air-dried stomata of Shiraia bambusicola (each pellet weights 0.1 g , amount to 10 pellets were saturated by 100 mL of Et-OH .Then we dilute the extract by 10 times and determine the absorption at the wavelength of 465 nm after 8 days .
