Research Progress in Chemical Constituents of Qi-Gui-Yin Compound / 世界科学技术-中医药现代化

ABSTRACT

Qi-Gui-Yin (QGY) compound, which composes of five herbal medicines of Astragalus membranaceus (Fisch.) Bge., Angelica sinensis (Oliv.) Diels, Lonicera japonica Thunb., Artemisia annua L., and Polygonum cuspidatum Sieb.et Zucc., which is able to treat antibiotic-resistant bacteria with antibiotics, and also to delay or even reverse the bacterial resistance producing. However, QGY compound is a complex mixture. And it is very difficult to elaborate its material foundation. Therefore, chemical constituents in five herbal medicines were summarized through searching of the related literatures. And then, 170 kinds of bioactive ingredients were classi-fied in order to provide evidences for the study on chemical constituent of QGY compound and identify its mate-rial foundation of delaying drug resistance .
