摘要
为了掌握竹红菌甲素的测定方法 ,测得了竹红菌甲素吸收曲线 ,研究了不同体质分数乙醇溶液浸提、不同浸提时间、竹黄子座不同颗粒度和不同乙醇用量对竹红菌甲素提取效果的影响。结果表明 ,竹黄子座中竹红菌甲素含量最佳测定方法是将颗粒度为 0 1g·颗 -1的竹黄子座风干品 1 0颗浸泡于 1 0 0mL无水乙醇中 ,8d后 ,稀释 1 0倍 ,于 465nm波长下测定吸光度。图 1表 3参 1
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.
