Biologically active constituents of leaves and roots of Aloe arborescens var. natalensis. Hirata, Toshifumi; Suga, Takayuki (Fac. Sci., Hiroshima Univ., Hiroshima, Japan). Z. Naturforsch., C: Biosci., 32C(9-10), 731-4 (English) 1977. CODEN: ZNCBDA. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 Several biol. active substances, such as aloenin (I) [38412-46-3], Mg lactate [18917-93-6], aloe-emodin (II) [481-72-1], barbaloin (III) [1415-73-2], and succinic acid [110-15-6], were found in the leaf juice of A. arborescens which has been widely used in domestic medicines. I and Mg lactate inhibited gastric juice secretion in rats. Various constituents other than the above bioactive substances were also found in the leaves and roots of the plant.
