【摘要】 为制定本品质量标准,本研究采取专家研究确定基原和名称,并依据药典指导方法进行各项理化指标分析,确定本品基原为麦角菌科真菌冬虫夏草菌经浅层静止培养后的干燥菌核,中文名称为冬虫夏草耳型菌核,性状为不规则的圆形或耳形片状;直径4~10 cm,厚1~4 mm;表面淡黄色至黄褐色;质脆易断裂;断面菌肉类白色至黄褐色。气香特异,味微甜。显微鉴别本品切面全体由菌丝紧密交织而成。外层菌丝棕色,不易分离;内部菌丝无色,常交错成团,弯曲,直径2~10 μm,有的可见分隔,分枝或呈结节状膨大。薄层色谱法和聚合酶链式反应鉴别本品均与标准药材一致。暂定含尿苷、鸟苷、腺苷总含量不得少于0.1%;水分不得超过6.0%;总灰分不得超过6.0%;酸不溶性灰分不得超过4.0%;温度(18±2)℃,湿度(60±5)%条件下贮藏18个月,样品性状、鉴别、水分、水溶性浸出物、含量、微生物等项目与初始相比几乎无变化,试验数据表明冬虫夏草耳型菌核存放较为稳定。拟定冬虫夏草耳型菌核贮藏条件为密封、阴凉干燥处。

【Abstract】 In order to formulate the sample quality standard, this study adopted expert research to determine the origin and name, and analyzed various physical and chemical indicators according to the pharmacopoeia guidelines. The origin of this product was determined to be Cordyceps sinensis (Berk.) Sacc. dried sclerotia after shallow stationary culture. Chinese name is Dongchongxiacao erxing junhe. The shape of Cordyceps sinensis auricula is irregular round or auricle-shaped flakes, diameter 4-10 cm, thickness 1-4 mm, surface light yellow to yellow-brown, fragile and easy to break, section fungus meat is off-white to yellow-brown, the smell is peculiar, and the taste is slightly sweet. Microscopic identification The entire section surface of this product is closely intertwined with hyphae. The outer hyphae are brown and difficult to separate, the inner hyphae are colorless, often staggered into clusters, curved,and with a diameter of 2-10 μm, Some of it are separated, branched or nodular-swelling. Through thin layer chromatography and polymerase chain reaction to identify this product is consistent with standard medicinal materials. The tentative total content of uridine, guanosine and adenosine shall not be less than 0.10%, moisture, total ash and acid-insoluble ash shall not exceed 6.0%, 6.0% and 4.0% respectively. Storage for 18 months under the condition of temperature (18±2)℃ and humidity (60±5)%. The sample properties, identification, moisture, water-soluble extract, content, microorganisms and other items were almost unchanged compared with the initial period. The experimental data showed that the storage of Cordyceps sinensis auricula was relatively stable, the proposed storage conditions of Cordyceps sinensis auricula are airtight, cool and dry places.
