Research Progress on Chemical Constituents,Extraction Methods and Pharmacological Effects of Sauropus spatulifolius Beille

Sauropus spatulifolius Beille is a small evergreen shrub in Sauropus of the Euphorbiaceae family.It mainly contains chemical components such as amino acids,proteins,carbohydrates,polypeptides,glycosides,saponins,tannins,organic acids,alkaloids,coumarin and lactones,volatile oils and oils.In addition,the chemical components obtained by different extraction processes are also different.S.spatulifolius Beille mainly has antitussive and expectorant,anti-inflammatory and analgesic,bacteriostatic,antioxidant,and anti-allergic effects.The rich biological activity of S.spatulifolius Beille makes it have clinical applications such as adjuvant treatment of pulmonary edema,recovery of lung function,and treatment of chronic laryngitis or chronic pharyngitis.In this paper,the main chemical components,extraction and identification methods and biological activity of S.spatulifolius Beille were described in depth,in order to further lay a solid foundation for the in-depth research,development and utilization of S.spatulifolius Beille.

不同栽植环境下守宫木的生理响应及其耐阴性评价

为探究不同栽植环境对守宫木[Sauropus androgynus(L.)Merr.]生理特性的影响,并对其耐阴性进行评价,以3年生守宫木扦插苗为研究对象,分别在露天(100%光照强度)、林下(65%光照强度)、大棚(30%光照强度)3种环境下栽植,测定不同环境下守宫木叶片光合色素含量、瞬时光合特性及渗透调节物质含量。结果表明,林下种植、棚下种植守宫木的叶绿素a及叶绿素(a+b)含量均极显著高于露天环境;随着遮阴程度的增加,叶片净光合速率先增后减,在林下种植时最高,而气孔导度、胞间CO_(2)浓度及蒸腾速率则表现为露天种植>林下种植>棚下种植,随着遮阴程度的增加逐渐下降。可溶性糖、可溶性蛋白质含量随着遮阴程度增加而先升后降,林下种植时达到最大;游离脯氨酸和MDA含量随着遮阴程度增加不断下降,露天种植时达到最大。隶属函数分析表明,林下环境的守宫木植株光合及生理状态最佳,过强或过弱光照环境均不适合其生长。
