The major results obtained are: PCR-RFLP method is suitable for molecular identification of Shihu; 205 compounds were isolated from 10 species of Dendrobium, including 21 new compounds, and 28 compounds isolated from genus Dendrobium for the first time. Each of the extracts and compounds were screened for anticoagulant and antitumour activities separately. The results indicated that the ethyl acetate extract from Dendrobium chrysanthun has significant anticoagulant function; the antitumour function of the 4 bibenzyl components from Dendrobium chrysotoxum is stronger than that of phenanthrene, of which the erianin has significant anti-angiogenic effect both in vivo and in vitro; components with moderate or stronger antitumour activities were found in the extracts of D. thyrsiflorum, D. chrysanthun and D. trigonopus; quality standard for 5 species of Dendrobium was drawn up use active or indicative components as control.

重要研究结果有：经方法学研究，认为PCR-RFLP法适于作为石斛属药材分子标记鉴定方法；对10种石斛进行化学成分分离鉴定，共分得205个化合物，其中新化合物21个，首次从石斛属分得的28个；对提取物和各单体化合物分别作抗凝血、抗肿瘤等活性筛选，结果说明束花石斛乙酸乙酯部位有显著的抗凝血作用，鼓槌石斛的4个联苄类成分抗肿瘤作用强于菲类，联苄类毛兰素在体内外有显著抗血管生成活性，球花石斛、束花石斛及翅梗石斛均筛到中等或较强抗癌活性的成分；选择有活性或指标性成分作对照品，对5种石斛草拟了质量标准。
