查询词典 Dendrobium

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.
