【摘要】：采用HPLC測(cè)定10個(gè)產(chǎn)地硬萼軟紫草根中4種萘醌類(lèi)成分含量,比較其差異。以乙酰紫草素、去氧紫草素、異丁酰紫草素、(2-甲基正丁�；�)紫草素為對(duì)照品,采用Agilent-C_(18)(250 mm×4.6 mm,5μm),以乙腈-0.05%甲酸水溶液(70∶30)為流動(dòng)相,1 m L/min,檢測(cè)波長(zhǎng)275 nm,柱溫30℃。4種成分分離良好,線性、重復(fù)性以及回收率均符合要求。不同產(chǎn)地的樣品中4種化學(xué)成分含量存在差異,可能與植物的生境及采收時(shí)間有關(guān),活性成分乙酰紫草素、(2-甲基正丁�；�)紫草素在各樣品中含量較高,推斷其可作為天然抗腫瘤成分及其衍生物的備選資源,為其資源開(kāi)發(fā)利用提供參考依據(jù)。
[Abstract]:The content of four naphthoquinones in the roots of 10 producing areas was determined by HPLC, and the difference was compared. Acetyl porphyrin, deoxysin, isobutylol porphyrin, 2-methyl-n-butylol) porphyrin were used as reference substances. Agilent-Cacenton (250 mm 脳 4.6 mm) was used as mobile phase, acetonitrile-0.05% formic acid solution (70: 30) as mobile phase, detection wavelength 275 nm, column temperature 30 鈩，
