山核桃青皮化学成分及生物活性研究进展

山核桃是我国皖浙交界处的特有作物,其果仁味美、营养丰富受到广大消费者喜爱。但对于包裹果壳的青皮的利用还很有限,根据近年来的研究及传统中医理论表明,胡桃科果实的青皮、树皮和根均含有对人体有益的成分,具有杀菌消炎、镇痛、抗肿瘤等作用,且由于其生化他感作用可应用于农作物除虫害。但上述功能活性的作用机理迄今尚不十分明了,有待于进一步研究。此外,对于山核桃青皮中多糖成分的研究未见报道,植物多糖具有明显的免疫调节活性和抗肿瘤作用,对山核桃青皮多糖组成进行分离纯化,并研究其生物活性,有助于进一步全面开发利用山核桃这一经济作物。

Research progress on chemical compounds of the green peel of carya cathayensis Sarg.and its biological activity

Carya cathayensis Sarg.is a special local product at the boundary of Zhejiang and Anhui province.It is popular within people not only for its daintiness but also for its nutrition.However its green peel has not been fully used yet.According to the reports in different countries and the traditional Chinese medicine theory,there are some chemical compounds in the green peels,barks and roots of Juglandaceae trees which are sanative such as sterilization,diminishing inflammation,easing pain,anti-tumor effect.Also its allelopathy effect can be used in insect killing.But the functional mechanism of those raw material is still under ambiguity,and is worthy of further investigation.Furthermore there are no reports about polysaccharide in Juglandaceae trees.It can help us to further utilise carya to extract the polysaccharide and identify its biological activity for polysaccharide in plant has showed obvious immunity adjustment and anti-tumor effect.
