Application of high-speed liquid chromatography in phytochemistry. He, Xian-Guo; Jiang, Fu-Xiang; Zhou, Qian-Ru (Shanghai Inst. Mater. Med., Academia Sinica, Shanghai, Peop. R. China). Chih Wu Hsueh Pao, 20(1), 76-83 (Chinese) 1978. CODEN: CHWHAY. ISSN: 0577-7496. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 The chem. constituents from the fruit and roots of 5 species of Chinese medicinal plants were analyzed by using a high-speed liq. chromatog. system. The major components of Camptotheca acuminata were 10-hydroxycamptothecin [67656-30-8], camptothecin [7689-03-4], 10-methoxycamptothecin [19685-10-0], and vincoside lactam [23141-27-7]. Quercetin [117-39-5], quercitrin [522-12-3], and subgallate [67674-83-3] were the main components of Euphorbia heliascopia Linn. The root exts. from Salvia miltiorhiza Bge. contained mostly tanshinone I [568-73-0], methylene tanshiquinone [67656-29-5], and tanshinone IIA [568-72-9]. The major constituents from fruits of Schisandra sphenanthera Rehd. et Wils. were schisantherin A [58546-56-8],B [58546-55-7], and C [64938-51-8]. The root exts. from Daphne genkwa Sieb et Zucc. consisted mostly of yuanhuacin [66673-22-1]. The packings for liq. chromatog. as well as the therapeutic effects of these chem. compds. are discussed.

Studies on the constituents of Lyonia ovalifolia Drude var

Studies on the constituents of Lyonia ovalifolia Drude var. elliptica Hand.-Mazz. (XXI). The difference of flavonoid glycosides between individuals. Kato, Yosisige; Yasue, Masaiti (Fac. Pharm. Sci., Tokushima Univ. Arts Sci., Tokushima, Japan). Shoyakugaku Zasshi, 37(4), 412-17 (Japanese) 1983. CODEN: SHZAAY. ISSN: 0037-4377. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 Flavonoid compds. in the leaves of L. ovalifolia Drude var. elliptica Hand,-Mazz. collected from various places in Japan were studied by paper chromatog. The plants were sepd. in 3 groups; one group contained dihydroquercetin 3-rhamnoside [29838-67-3], quercetin 3-rhamnoside [522-12-3], and quercetin 3-galactoside [482-36-0], the second group quercetin 3-rhamnoside and quercetin 3-galactoside, and the 3rd group quercetin 3-galactoside. The constituents in the wood were independent of the place of growth. The amt. of toxic substances and that of triterpenoid glycosides were not related to those of flavonoids.
