1-Acetyl-4-methoxy-β-carboline (I), canthin-6-one (VIIIa), 1-methoxycanthin-6-one (VIIIb), and canthin-6-one-3N-oxide (IXa), and three new alkaloids, 1-(2'-hydroxyethyl)-4-methoxy-β-carboline (IIa), 1-(1', 2'-dihydroxyethyl)-4-methoxy-β-carboline (IIIa), and 1-methoxycanthin-6-one-3N-oxide (IXb), were isolated from the root bark of Ailanthus altissima SWINGLE (Simaroubaceae). The structures of IIa, IIIa, and IXb were elucidated by spectroscopic and chemical studies.
从臭椿(Simaroubaceae)的根皮中分离出1-乙酰基-4-甲氧基-β-咔啉(I)、坎亭-6-酮(VIIIa)、1-甲氧基坎亭-6-酮(VIIIb)和坎亭-6-酮-3N-氧化物(IXa)以及三种新的生物碱:1-(2'-羟乙基)-4-甲氧基-β-咔啉(IIa)、1-(1', 2'-二羟乙基)-4-甲氧基-β-咔啉(IIIa)和1-甲氧基坎亭-6-酮-3N-氧化物(IXb)。通过光谱和化学研究阐明了IIa、IIIa和IXb的结构。
