An antibacterial composition having xanthorrizol is provided. The xanthorrizol is prepared by obtaining crude extract having antibacterial activity from Curcuma xanthorriza Roxb. lysate by the aid of solvent extraction, supercritical fluid extraction, microwave extraction or ultrasonic extraction; applying the crude extract to chromatography to obtain active fraction; acetylation of the active fraction to change its polarity and applying to chromatography to isolate an acetylated single compound; and, deacetylation of the acetylated single compound to give xanthorrizol having antibacterial activity. Since xanthorrizol has potential antibacterial activity over a broad spectrum of microorganisms under a wide range of temperature, it can be practically applied to antibacterial agent, tooth paste, oral cleanser, chewing gum, soap and cosmetics which require the antibacterial activity.
提供一种含有黄芪醇的抗菌组合物。黄芪醇是通过从Curcuma xanthorriza Roxb.裂解液中利用溶剂提取、超临界流体提取、微波提取或超声波提取获得具有抗菌活性的粗提取物,将粗提取物应用于色谱法以获得活性分数,醋酸化活性分数以改变其极性,然后将其应用于色谱法以分离乙酰化的单一化合物,去乙酰化乙酰化单一化合物以得到具有抗菌活性的黄芪醇制备而成。由于黄芪醇在广泛的微生物谱下具有潜在的抗菌活性,并且在广泛的温度范围内具有抗菌活性,因此可以实际应用于需要抗菌活性的抗菌剂、牙膏、口腔清洁剂、口香糖、肥皂和化妆品。
