目的 對(duì)傳統(tǒng)中藥荊芥Schizonepeta tenuifolia(Benth.) Briq.中的單萜類化學(xué)成分進(jìn)行研究。方法 溶劑提取、柱層析分離純化、光譜測(cè)定化學(xué)結(jié)構(gòu)。結(jié)果 從中藥荊芥的全草中分離得到2個(gè)新的和3個(gè)已知的單萜類化合物。結(jié)論 根據(jù)理化性質(zhì)和光譜數(shù)據(jù),新化合物的結(jié)構(gòu)鑒定為3-羥基-4(8)-烯-對(duì)-薄荷烷-3(9)-內(nèi)酯;1,2-二羥基-8(9)-烯-對(duì)-薄荷烷。

Object To study the chemical constituents of Schizonepeta tenuifolia (Benth.) Briq.. Methods The monoterpenoid constituents of S. tenuifolia were separated on silica gel column and their structures were elucidated by spectral. Results Two new compounds and three known compounds were obtained. Conclusion The new compounds were identified as 3-hydroxy-4(8)-ene-p-menthane-3(9)-lactone and 1, 2-dihydroxy-8(9)-ene-p-menthane.
