利用新的手性选择剂苄基氯化辛可宁，在非水相中成功地分离了联萘酚对映体，并对分离的机理作了初步地探讨。

METHODS: A series of N-octyl-N'-succinyl chitosan labeled with fluorescein, were incubated with HepG2 liver cancer cells, K562 leukemia cells, A549 human lung cancer cells, and BGC cancer cells respectively and followed by using flow cytometry and enzyme-linked immunosorbent assay to assess the affinity and inhibition of N-octyl-N'-succinyl chitosan for the four kinds of tumor cells already mentioned.

用异硫氰酸荧光素对N-正辛基－N'-琥珀酰基壳聚糖进行标记，再分别与人肝癌细胞(HepG2)、人白血病细胞(K562)、人非小细胞肺癌细胞(A549)及人胃癌细胞共培养，通过流式细胞仪及酶联免疫检测仪测定N-正辛基－N'-琥珀酰基壳聚糖对肿瘤细胞的亲和性及抑制力。

The chiral polymer P-1 shows strong blue fluorescence due to the extended π-electronic structure between the chiral repeating unit-6,6'-di(4-trifluoromethyl-phenyl)-2,2'-bisoctoxy-1,1'-binaphthyl and the conjugated linker 2,2'-bipyridyl group via vinylene bridge.

手性高分子P-1能发射强的蓝色荧光，这是由于手性重复单元-6，6′-二(4-三氟甲基苯基)-2，2′-二正辛氧基-1，1′-联萘和单元2，2′-联吡啶通过亚乙烯基桥连形成共轭高分子结构造成的。

The present doctoral dissertation was carried out to study the chemical constituents isolated from stems of two medicinal schisandraceous plants.34 compounds were isolated from the ethanol extracts of the stems S.henryi collected in the Jiangxi province by various column chromatographies.27 of them were identified on the basis of spectral analysis.There are 18 lignans,(including 5 dibenzocyclooctadienes,6 aryltetralins,2 tetrahydrofurans,3 diarylbutanes,2 other lignans),3 flavanols,2 glyceroesters,1 naphthoquinone,1 xanthine and 2 steroids,of which 6 compounds were new compounds,and 7 compounds were isolated from this family for the first time.

采用多种色谱技术进行分离纯化，从翼梗五味子藤茎的乙醇提取物中分离到34个化合物，综合运用现代波谱学技术鉴定了27个化合物，包括木脂素类化合物18个(其中联苯环辛烯类木脂素5个，芳基四氢萘类木脂素6个，四氢呋喃类木脂素2个，二芳基丁烷类3个，其他类型木脂素2个)，黄烷醇类化合物3个，甘油酯类化合物2个，萘醌类化合物1个，黄嘌呤类化合物1个，甾体类化合物2个，其中，5个为新化合物，7个为本科首次报道。
