Valeriana; X-ray diffraction; anti-inflammatory activity; inhibitory concentration 50; irradiation; macrophages; nitric oxide; sesquiterpenoids; spectral analysis; stereochemistry
Abstract:
... One new sesquiterpene 1S, 3S, 4S, 7S 3,4-dihydroxy-bisabolol (1), one new iridoid amurensin A (2) and 10 known compounds were isolated from the whole plants of Valeriana amurensis. Their structures were established on the basis of extensive spectroscopic analysis and the absolute stereochemistry of compound 1 was assigned by X-ray diffraction analysis with Cu-Kα irradiation. All of compounds were ...

Abstract:
... Two new sesquiterpenes (1 and 2), one new alkaloid (4), one new neolignan glycoside (14), together with 19 known compounds were isolated from the branches of Alangium barbatum. Their structures were established by spectroscopic analysis. The absolute configuration of 21 was determined for the first time by single-crystal X-ray diffraction analysis with Cu-Kα irradiation. Some of isolates were eval ...
