The main results are as follows:① The contents of the seven elements in both the mosses and the substrates are much higher than those normal condition;② Didymodon fallax has stronger capacity to accumulate the element Cd. It can be as the indicator of Cd;③ Comparing with the other 4 mosses, Bryum dichotomum possesses stronger enriching function for Cu, Zn, and Pb.

结果表明，铜山口铜矿这5种藓类植物体内及其生长基质中，Cu、Zn、Ca、Mg等4种元素含量较高；北地对齿藓对Cd有较强的富集能力，可以作为寻找Cd矿的特征植物；相对于其它4种藓类植物，双色真藓对Cu、Zn、Pb有较强的富集能力，可以作为寻找Cu矿、Zn矿、Pb矿的参考植物；舌叶毛口藓对Hg有一定的富集能力，可以作为寻找Hg矿的参考植物。

The free radical scavenging properties of six Aloe species are to be investigated in some modified chemical system. The antioxidant was purified by silica column and thin layer chromatography and analyzed by HPLC. A fraction was purified from A. brevifolia Mill showed the most effective scavenging activities on 〓 and ·OH (66. 01% and 38. 98% respectively). With the analysis of IR spectrum, UV spectrum and mass spectrum, the structure of FA was identifed as 8-C-D-glucopyranosyl-2- [2-hydroxy] propyl-5-methyl-7-hydroxychromone. Its scavenging activity on free radicals is higher than that of aloe-emodin. Its antioxidant activity may be due to the phenoxyl on glucosyl chromone which can be react with free radicals and form relatively stable free radicals.

本研究利用分别产生超氧阴离子自由基和羟自由基的化学模型体系研究比较了不同品种芦荟提取物的清除活性氧自由基的抗氧化作用，进一步利用硅胶柱结合薄层层析法和反相高压液相色谱法，从短叶芦荟叶子中首次分离了具有较强自由基清除能力（超氧阴离子自由基和羟自由基清除率分别为66.01％和38.98％）的成分FA，利用红外光谱、紫外光谱和质谱等仪器分析结果推断出该活性成分的分子结构为8-C-吡喃葡萄糖-2-[2-羟基]-丙基-5-甲基-7-羟基对氧萘酮，它的自由基清除能力高于芦荟大黄素，是一种天然抗氧化剂。
