黄精为我国传统药食两用中药材,是历代用于补气养阴,健脾益肾之良药,含有较高的药用价值。植物资源丰富,广泛分布于我国南方地区。大量研究发现,药用黄精化学成分复杂多样,已从黄精中分离得到主要活性成分为黄精多糖、甾体皂苷、黄酮等多种成分,以上成分均具有抗肿瘤活性。在广泛查阅文献的基础上,对近年来黄精的化学成分及抗肿瘤的物质基础进行系统综述,黄精中已经发现的抗肿瘤化学成分主要有多糖、皂苷、黄酮、挥发性成分及凝集素等,抗肿瘤治疗效果与机制的实验研究多采用黄精水提取物或醇提物,在乳腺癌、肺癌、宫颈癌、胃癌及肝癌等体外实验研究中,均表现出阻滞肿瘤细胞周期,诱导细胞凋亡的作用。本文梳理了目前黄精多糖的化学结构、各成分抗肿瘤作用以及对黄精产业化开发和前景进行分析和展望,以期为黄精的深入系统研究、资源的有效开发利用提供科学参考。 相似文献

A new saponin, isonarthogenin 3-O-β-d-glucopyranosyl-(1→4)-β-d-galactopyranoside (1), together with twelve known compounds, were isolated from the rhizomes of Polygonatum sibiricum. The structures of these compounds were elucidated by analysis of their 1D/2D NMR and MS data. Among them, phenol compounds 4–7 and 9–10 showed significant inhibitions against the formation of advanced glycosylation end products, with IC50 values of 0.091 ± 0.0021, 0.10 ± 0.041, 0.014 ± 0.0027, 0.11 ± 0.011, 0.13 ± 0.045, and 0.055 ± 0.019 μM, respectively. The results will promote exploiting potential medicinal use of these compounds in the prevention of diabetic complications and supporting Polygonatum sibiricum as a functional food for healthy and medicinal diet. 相似文献

A new homoisoflavanone, (3R)-5-hydroxy-7-methoxyl-3-(2′-hydroxy-4′- methoxybenzyl)-chroman-4-one (1), together with six known analogs, were isolated from the rhizomes of Polygonatum sibiricum. Their structures were elucidated on the basis of extensive spectroscopic analysis. All compounds were tested for their estrogenic activity using the MCF-7 estrogenresponsive human breast cancer cell lines. At a dose of 0.1 μmol/L, compounds 1–7 exhibited significant proliferative effects on MCF-7 cells compared with E2. The molecular docking study results indicated that the activity of compounds 3, 5, 6, and 7 may be the binding with ERR. 相似文献
