Textual research on original plant of Chinese herbal medicine Cyrtomium Rhizome / 中国中药杂志

Through studies on morphological characteristics, distribution and ecological habitat described in ancient literatures, Osmunda japonica is believed to the original plant of Chinese herbal medicine Cyrtomium Rhizome. Meanwhile, analysis is also made on causes for descriptions that do not comply with characteristics of O. japonica such as toxicity, flowers and fruits, illustrations, indumentums and flakes as well as appearance of other original plants. It is suggested to list O. japonica as the only original plant of Cyrtomium Rhizome and distinguish it from other frequently seen medical plants. Separated studies are also conducted for pesticide effect and active ingredients of Dryoteris Crassrhizomae Rhizome and Woodwardia japonica that show better effects.

Studies on chemical constituents of Arachniodes rhomboidea / 中国中药杂志

<p><b>OBJECTIVE</b>To study chemical constituents of Arachniodes rhomboidea.</p><p><b>METHOD</b>Silica gel column chromatography and Sephadex LH -20 gel column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectral data and chemical methods.</p><p><b>RESULT</b>Six compounds were isolated and identified as follows: kaempferol (1), kaempferol-3-O-alpha-L-rhamnoside (2), kaempferol-3-O-beta-D-glucoside (3), kaempferol-3, 7-O-alpha-L-dirhamnoside (4), quercetin-3-O-beta-D-glucoside (5), kaempferol-3-O-beta-D-rutinoside (6).</p><p><b>CONCLUSION</b>Compouds 1-6 were isolated from this plant for the first time.</p>
