Phytochemical investigation of seed coats of Pterospermum acerifolium afforded two phytoceramides (1, 2) and two acylated phytosterol glucosides (3, 4) together with five known compounds (5-9). Their structures were elucidated on the basis of extensive spectroscopic analysis using 1D, 2D NMR and Mass spectrometry. Compounds 1, 2, 3, and 4 were assessed for their osteogenic activity using primary cultures
对紫叶紫檀种皮的植物化学研究提供了两种植物神经酰胺 (1, 2) 和两种酰化植物甾醇葡糖苷 (3, 4) 以及五种已知化合物 (5-9)。基于使用 1D、2D NMR 和质谱法的广泛光谱分析,阐明了它们的结构。使用从新生大鼠颅盖骨收获的成骨细胞的原代培养物评估化合物1、2、3和4的成骨活性。在这些化合物中,1 和 2 显着刺激了通过碱性磷酸酶产生评估的成骨细胞分化和通过茜素红-S 染色评估的成骨细胞矿化。
