石菖蒲;天南星科;酚性成分;三萜
石菖蒲(Acorus tatarinowii Schott.)系天南星科(Araceae)菖蒲屬多年生草本植物,其根莖為傳統(tǒng)中藥,主產(chǎn)四川、浙江、江蘇等地,四川產(chǎn)者為道地藥材。石菖蒲《神農(nóng)本草經(jīng)》列為上品,味辛性溫,具芳香之氣,行散之力強,為宣氣通竅之佳品。中醫(yī)學(xué)認(rèn)為石菖蒲的功能主要是開竅豁痰、醒神益智、聰耳明目、化濕開胃和散寒除痹。臨床廣泛用于癲癇、痰厥、熱病神昏、健忘、老年癡呆等疑難病的治療[1]。菖蒲屬植物主要含倍半萜[2],苯丙素[3]和糖[4]等成分[5,6],在我們對石菖蒲的系統(tǒng)研究中,曾經(jīng)報道了從中分離得到的具有抗氧化作用的結(jié)構(gòu)新穎的螺環(huán)生物堿、倍半萜、細(xì)辛醚類以及吡嗪類生物堿[7-9]。本文對其它酚性成分及三萜等18個化合物進行報道,其中15個系首次從該種中分離得到。
