For a long time, due to the shortage of a objective and clear method and standard for the quality evaluation of the Dao-di herb, it is difficult to distinguish the Dao-di herb. Geo-herbalism and environment-related studies often fall into the vicious circle of "have target but no indicators" and "circular reasoning" because of lack of objective and a clear(More)
How to identify active constituents of traditional Chinese medicines (TCMs) and study their interactions are key problems in the development of TCMs. The inhibitory effect of six alkaloids from Rhizoma Coptidis (RC) on Shigella dysenteriae (S. dysenteria) growth had been investigated by microcalorimetry in this study. Main active constituents of RC were(More)
OBJECTIVE To compare the difference in clinical efficacy on lumber disc herniation (LDH) treated with Yaoyangguan (GV 3) between mild moxibustion under thermosensitive condition and that under non-thermo-sensitive condition. METHODS Fifty-seven LDH patients were selected as the study objects. Mild moxibustion at Yaoyangguan (GV 3) was applied for 45 min(More)
In the title compound, C(30)H(39)OP, the P=O bond length is 1.4866 (12) Å and the P-C bond lengths range from 1.804 (2) to 1.808 (13) Å. The molecle is located on a crystallographic mirror plane. The methyl groups of one tert-butyl group are disordered over two sites in a 0.776 (4):0.224 (4) ratio.
Under rhodium(III) catalysis, four kinds of cycloalkenecarboxylic acids successfully reacted with acrylates via direct activation of the β-alkenyl C-H bond. The present protocol provides the facile and highly efficient synthesis of substituted furan-2(5H)-ones from readily available starting materials with moderate to good yields. In addition, their(More)
