Abstract:
Jin Xian Lian (Anoectochilus roxburghii (will.) lind-waldock.), which belongs to the genera Anoectochilus (Orchidaceae), is a perennial herbaceous plant. Itis also known as Jin Si Xian, Jin Er Huan, Wu Ren Shen, Jin Xian Hu Tou Jiao, Jin Xian Ru Gu Xiao and Jin Qian Cao. Jin Xian Lian is widely distributed in Fujian, Zhejiang, Guangxi and other regions. Particularly, highly ornamental value was endowed with Jin Xian Lian because of the small plant type, the golden yellow leaves and the reticular arrangement of veins. Jin Xian Lian has been widely used as a "medicine and food homology" plant in folk for a long time, and it could be used for treating diabetes, haemoptysis, acute hepatitis, bronchitis and cancer due to the characteristics of mild and sweet flavor. Jin Xian Lian is safe and has no toxic effects, which attract more and more researchers’ attention. The results of chemical analysis showed that the chemical constituents of Jin Xian Lian are really abundant, including flavones, volatile oils, polysaccharides, alkaloids and steroids. In addition, modern pharmacological studies suggest that Jin Xian Lian has the fuctions of hypoglycemic, cardiovascular protection, anti-infection and antitumor. This article systematically reviews the material foundation and biological activities of Jin Xian Lian, providing a reference for the development of natural health products.
