Several anti-tumor cell lines and carbonic anhydrase Ⅱ model were established. More than 10000 compounds and extracts from plants were screened using these models and about 10 compounds showed strong inhibitory activities. Two species of plants Inula helianthus-aquatica and Saussurea deltoidea were chosen to investigate chemical and bioactivity constituents based on the results of screening of extracts and fractions. 58 compounds were isolated and identified from these two plants, 6 compounds were found to be new and 14 compounds showed anti-tumor activities. We also studied the anti-tumor mechanism of the compound bigelovin isolated from Inula helianthus-aquatica. Bigelovin was found with apoptotic activity against cell line U266 by lowering the amount of important transcription factor E2F-1 which inhibits the cell cycle at G0/G1 stage. Docking study on 7 natural new phenolic inhibitors of CA Ⅱ and 3D-QSAR study on 61 sulfonamide inhibitors of CA Ⅱwere also investigated. The calculated results were in good correlation with experimental results.

基于以上两种重要疾病和研究组方向，本论文工作开展了多个肿瘤细胞株和碳酸酐酶Ⅱ靶标模型的建立和筛选工作，累计筛选1万多个/次样品，发现10余个活性较强化合物；从粗提取物筛选结果中选取两种抗肿瘤活性强的菊科植物水朝阳旋覆花(Inula helianthus-aquatica)和三角叶凤毛菊进行了系统化学和活性成分研究，分离鉴定了58个化合物，发现6个新化合物和14个抗肿瘤活性化合物；通过合作对水朝阳旋覆花中活性较强的bigelovin进行了抗肿瘤作用机制研究，发现它可能是通过降低G2期重要的转录因子E2F-1，致使细胞周期阻滞在G0/G1期，引起多发性骨髓瘤U266细胞凋亡；开展了7个新的天然酚类CAⅡ抑制剂的对接研究和61个合成的系列磺酰胺类CAⅡ抑制剂的3D-QSAR分析，结果表明计算与实验一致。

因梨中含有较多的配糖体和鞣酸成分以及多种维生素，故高血压、心肺病，肝炎、肝硬化病人出现头昏目眩、心悸耳鸣时，常吃梨大有好处。

And the scientific research showed that they are medicable to insomnia, anxiety and other diseases that found in modern people. 4 The regression models of biomass were used to calculate the total cumulative biomass. Average biomass of six samples was 62.88 t·hm-2 after cutting 3 years, which was higher than that of tropical secondary forests with 5 years succession. It can be concluded that traditional fuel woods had played an important role in conservation of tropical forest in the area. Caloric values were not different in major fuel species (Coefficient of variation was only 1.1%). The similar result was found in stems of C. siamea after growing different years. The main reason of C. siamea cultivation was that it had the character of hardwood, easy collecting, little ash, and so on.

铁刀木的各个部位都作药用，资源量大的树叶和心材使用最多，并且现有的研究成果表明它们具有多种活性成分，针对现代人常患的失眠、焦虑等疾病具有较好疗效。4）通过收获法拟合的生物量回归模型对推测西双版纳地区铁刀木林薪柴蓄积量有较高的参考价值，砍伐3年后的六个样方中铁刀木的平均生物量为62.878 t.hm-2，高于5年林龄的热带次生林（16.35t·hm-2），对西双版纳热带雨林的保护有着重要意义。5）几个村寨最主要的薪材树种热值研究结果变异系数仅为1.1％，各薪材树种之间热值相差不大，铁刀木被选择为传统薪炭林更多是因为材质坚硬、收获运输方便、燃烧完全等特点。
