八角茴香又称八角，为木兰科八角属植物Illicium verum Hook．f．的果实，其味辛、性温，有温阳散寒、理气止痛功效，用于寒疝腹痛、肾虚腰痛等症。长期以来八角果实主要开发成分为挥发油类即八角茴香油，其有芳香调味和健胃作用。而八角还有另一大类成分即脂类化合物尚未深入研究，Kataoka E等报道了八角果实中总油脂占9．4％，脂类成分主要存在于种子中，刘莉玫等也初步报道八角种子富含棕榈酸、亚油酸、油酸和硬脂酸，共占油脂量的34．6％，但除此之外的其他脂肪酸成分未见研究。本研究利用CO_2超临界流体萃取技术提取八角种子油脂等成分，并对油脂进行甲酯衍生化，然后应用GC-MS技术对其中所含的脂肪酸成分进行系统分析研究，为进一步综合开发利用八角提供科学依据.

Two new compounds,schinifolin Ⅰ and acetoxyschinifolin Ⅱ,along with five known compounds(auraptenⅢ,dictamnine Ⅳ,scoparone Ⅴ,skimmianine Ⅵ,and β-sitosterol Ⅶ)were isolated from the roots of Zanthoxylum schinifolium *** ***- lected in Yixing County,Jiangsu *** structure determination was based upon spectroscopic analysis(UV,IR,MS,PMR,CMR,2D NMR).The structures of schinifolin Ⅰ and acetoxyschinifolin Ⅱ were elucidated as 7[(3′,7′-dimethyl-2′,6′-octadienyl)] oxy-8-methoxy-2H-1-benzopyran-2-one,and 7[(3′,7′-dimethyl-5′-acetoxy-2′, 6′-octadienyl)]oxy-8-methoxy-2H-1-benzopyran-2-one,respectively. In the test of platelet aggregation caused by PAF,compounds Ⅰ,Ⅱ,Ⅲ and Ⅴ showed inhibitory activity.
