Ziziphus zizyphus, commonly called jujube (sometimes jujuba), red date, Chinese date, Korean date, or Indian date is a species of Ziziphus in the buckthorn family Rhamnaceae, used primarily as a fruiting shade tree. The fruits are used in Chinese and Korean traditional medicine, where they are believed to alleviate stress, and traditionally for antifungal, antibacterial, antiulcer, anti-inflammatory, sedative,[7] antispastic, antifertility/contraception, hypotensive and Antinephritic, cardiotonic, antioxidant, immunostimulant, and wound healing properties. The known alkaloids mauritine-A, mucronine-D, amphibine-H, nummularine-A and -B and the previously undescribed jubanine-A and -B have been isolated from the stem bark of Ziziphusjujuba. The structures of the new compounds were elucidated by spectroscopic methods and by chemical degradation reactions.
