【摘要】目的 研究不同炮制工艺对蛇床子理化性质的影响,为临床用药提供研究的数据支持。
方法 按照中华人民共和国药典(2015年版)中蛇床子检验方法对蛇床子生品和炮制品的理化性质(水分,总灰分,酸不溶性灰分、浸出物和蛇床子素含量测定)进行比较。结果 生品蛇床子的含水量和蛇床子素含量较高,酥炙的蛇床子浸出物含量较高。结论 蛇床子炮制之后,蛇床子的主要活性成分蛇床子素的含量
降低。

【Abstract】Objective To explore the effect of different processing methods on the physicochemical properties and the content of osthole in Fructus Cnidii, and to provide basis for clinical medication.Methods according to People's Republic of China Pharmacopoeia (2015 Edition), Furtus Cnidii and the processed products with different methods were tests on the physical and chemical properties (water content,total ash,acid insoluble ash,content of water extract) and the content of osthole.Results Water content and content of osthole in original Fructus Cnidii was higher than that by heating process.Content of water extract in processed product by frying with butter was highest.Conclusion The content of osthole in Fructus Cnidii decrease with
heating process.

蛇床子是伞形科植物蛇床(Cnidium monnieri(L) Cuss.)的干燥成熟果实。夏、秋二季果实成熟时采收,除去杂质,晒干[1]。蛇床子外用能燥湿祛风、杀虫止痒,用于阴部湿痒、湿疹、湿疮、疥癣;并且它辛润而不燥,性温能助阳,入肾经而有温肾壮阳之功,故可用于肾阳虚衰所致的阳痿遗精,宫冷不孕等症[2]。《神农本草经》将蛇床子列为上品,言其“主男子阳痿,久服轻身”[3]。唐宋时期,蛇床子临床作为补虚常用药。明清以后,近代以来,蛇床子主要作外用,很少作内服。如《本草正义》提到蛇床子“绝少用为内服之药”[4]。
关于蛇床子的炮制首见于《雷公炮灸论》[5]“须用浓兰汁、并百部草根自然汁二味,同浸三伏时,漉出,日干。却,用生地黄汁相拌蒸,从午至亥,日干用”;《日华子本草》[6]有云“蛇床,凡合药服食即挼去皮壳取仁,微炒杀毒即不辣,作汤洗病则生使”;有文献认为蛇床子入药内服须经过炮制[7]。蛇床子的主要炮制方法有炒制、酒炙、酥炙等。……
