Abstract

2,4-Dimethoxy-2-methyl-6H-pyran-3-one (1), a hitherto unknown natural product, and the calcium salt of rehmapicroside (2) have been isolated from rhizomes of the Vietnamese variety of Rehmannia glutinosa Libosch together with a series of known compounds: norcarotenoids (3-5), 2-formyl-5-hydroxy-methylfurane (6), the iridoid rehmaglutin D (7), iridoid glycosides (8-12) and phenylethyl alcohol glycosides (13-17). Their structures were determined by mass and NMR spectroscopy.

摘要

从越南地黄的根茎中分离出了一种迄今未知的天然产物2,4-二甲氧基-2-甲基-6H-吡喃-3-酮（1）和地黄微苷钙盐（2），以及一系列已知化合物：去甲类胡萝卜素（3 - 5）、2-甲酰基-5-羟甲基呋喃（6）、环烯醚萜地黄苷D（7）、环烯醚萜苷（8 - 12）和苯乙醇苷（13 - 17）。通过质谱和核磁共振光谱确定了它们的结构。
