  1. 民間抗生與鎮痛藥材之開發第一報穀精子 • 清熱藥於中醫臨床上一般用以治療熱痢、癰腫、瘡毒等表現的裡熱。解表藥則有緩解疼痛、退熱、治麻疹、水痘等療效。此二類藥從現代醫學觀點來看,大致相當於抗菌、解熱、消炎、鎮痛﹒﹒﹒﹒等作用。本研究以清熱藥與解表藥為原則、收集五十種中藥材,做抗菌與鎮痛活性之評估。穀精子為所評估之藥材中兼具此二項明顯且有意義作用之一;因而進一步探究穀精子抽取物各劃分部分之抗菌、鎮痛、鎮靜與保肝等各項生理活性,發現每一劃分部分均有抗菌作用,正己烷與二氯甲烷部分有鎮痛作用,並且無中樞抑制之作用,而二氯甲烷部分的正己烷層則有明顯的保肝作用。由穀精子乙酸乙酯抽取物分離出鎮痛活性成分:(Ⅰ)由hexadecanoic acid 、octadecanoic acid 、eicosanoic acid 、docosanoic acid 與hexacosamol 、octacosanol 、triacontanol所形成之長鏈酯混合物。(Ⅱ)dotriacotanoic acid 、tetracontanoic acid 與hexacontanoic acid之混合物(Ⅲ)1﹣heptacosanol(46﹒0%)、1﹣octacosanol (5﹒0%)與1﹣nonacosanol (49﹒0%)之混合物,(Ⅴ)Stigmasterol((77﹒0%)與β﹣sitosterol(23﹒0%)之混合物,(Ⅵ)triglyceride,(Ⅶ)1﹣hexacosanol (42﹒6%)、1﹣octacosanol 1﹣octacosanol (41﹒9%)與1﹣triacotanol (15﹒5%)之混合物,(Ⅶ)semi﹣vioxanthin,(Ⅸ)homoplantaginin 。成分(Ⅶ)亦為抗菌活性成分,其對Staphylococcus aureus 的最低抑菌濃度為18ug∕ml,對Staphylococcus epidermidis為20gu∕ml,對Sa llus subtilis 為4ug∕ml,對Bacillus cereus 為8ug∕ml,對Micrococcus leteus為20ug∕ml,對Pseudomonas aeruginosa為18ug∕ml。經本研究生理活性之評估與分離出之活性成分證實穀精子確具抗生與鎮痛之療效,為臨床上值得開發之藥材。
