DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) 1-Carbomethoxy-b-carboline (I) [3464-66-2], 1-carboethoxy-b-carboline (II) [72755-19-2], 1-vinyl-4,8-dimethoxy-b-carboline (III) [65236-62-6], canthin-6-one (IV) [479-43-6] and 4,5-dimethoxy-b-canthin-6-one (V) [18110-87-7] in the stem of P. quassiuoides were detd. by HPLC. Thus, ~0.1-g powder was extd. with 25 mL MeOH, and the ext. was subjected to anal. by HPLC with a column contg. Nucleosil C18 as stationary phase [MeOH-NH4OAc (.1) as mobile phase]. The peak height was linearly related to concns. of 0.1-1.0 mg. Reproducibility with a relative std. deviation of 1.75-3.24% was obsd. Alkaloid concns. in the stem were 0.067, 0.011, 0.008, 0.096 and 0.012%, resp.

Studies on the constituents of Ailanthus altissima Swingle. III. The alkaloidal constituents. Ohmoto, Taichi; Koike, Kazuo (Sch. Pharm. Sci., Toho Univ., Funabashi 274, Japan). Chem.In this article, certain chemicals are used. Some of their cas registry numbers are 89915-39-9 and 3464-66-2 Pharm. Bull., 32(1), 170-3 (English) 1984. CODEN: CPBTAL. ISSN: 0009-2363. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) Two new alkaloids, 1-(2-hydroxy-1-methoxy)ethyl-4-methoxy-b-carboline and 5-hydroxymethylcanthin-6-one, were isolated from the root bark of A. altissima (Simaroubaceae), together with 3 known alkaloids, b-carboline-1-propionic acid, 1-carbamoyl-b-carboline, and 1-carbomethoxy-b-carboline. The structures were elucidated on the basis of spectral and chem. evidence. .
