This project studied the mechanism of a newfound phytotoxin from Alternaria alternata Keissler that infects Crofton weed. According with the result from experiment, the project group drew a conclusion that the toxin did not inhibit respiration in mitochondrion, so the key problem was whether the toxin inhibited photosynthesis in chloroplast.

本项目重点研究新近分离纯化的紫茎泽兰致病型链格孢菌毒素的致病机理，项目组依据实验结果排除了毒素抑制线粒体呼吸作用的可能性，把重点放在毒素对叶绿体光合作用的影响上。

本文从地质学、矿物学观点出发，阐明了西昌地区富硒的原因，指出：紫茎泽兰是新发现的一种含硒植物，提出了开发硒资源的设想与建议。

The yield, chemical components and relative contents of essential oil extracted from Eupatorium adenophorum Spreng by Soxhlet extraction and steam distillation were compared. The volatile chemical constituents of essential soil extracted were analyzed by Gas Chromatography-Mass Spetrometry. The results showed that the constituents of the volatile from the same plant and the relative contents were significantly different due to different extraction methods.

采用索氏提取器及水蒸气蒸馏两种方法对采于不同时间、不同产地的紫茎泽兰Eupatorium adenophorum Spreng挥发性成分进行了提取，比较了两种方法的得油率、化学组成及其相对含量；采用GC-MS联用技术对其中的挥发性成分进行了分析。
