New flavonoids were isolated from the aerial part of Artemisia frigida Willd. (Asteraceae). Their structures were elucidated using UV, IR, and NMR spectroscopy and mass spectrometry as chrysoeriol-7-O-(2′′-Oacetyl)-β-D-glucopyranoside (2′′-O-acetylthermopsoside), jaceosidin-4′ -O-β-D-glucopyranoside (isojaceoside), and 13 known flavonoids. The influence of the isolated compounds on α-glucosidase activity and triglyceride accumulation in 3T3-L1 preadipocytes was studied.
从冷蒿地上部分分离出新的黄酮类化合物。 (菊科)。使用紫外、红外、核磁共振光谱和质谱法阐明了它们的结构:chrysoeriol-7-O-(2''-O乙酰基)-β-D-吡喃葡萄糖苷(2''-O-乙酰基热木糖苷)、jaceosidin-4'- O-β-D-吡喃葡萄糖苷(isojaceoside)和 13 种已知的黄酮类化合物。研究了分离的化合物对 3T3-L1 前脂肪细胞中 α-葡萄糖苷酶活性和甘油三酯积累的影响。
