研究了冬虫夏草(Cordyceps sinensis)菌丝体热水提取物潜在的降低血胆固醇的作用。 材料和方法:①取冻干的冬虫夏草菌丝体(50g)于100℃褪色5min后,7 000 r/min匀浆20min,离心,残余物依次用乙酸乙酯、甲醇和热水提取。将热水提取液离心,上清液冻干,得到冬虫夏草菌丝体热水提取物 The potential of lowering blood cholesterol by the hot water extract of cordyceps sinensis mycelium was studied. Materials and Methods: 1) Lyophilized Cordyceps sinensis mycelia (50 g) was decolorized at 100°C for 5 min, homogenized at 7 000 r/min for 20 min, centrifuged, and the residue was extracted with ethyl acetate, methanol and hot water in that order. The hot water extract was centrifuged, and the supernatant was lyophilized to obtain Cordyceps mycelium hot water extract
