Numerical taxonamy of Paris plants / 中国中药杂志

Numerical taxonomic studies were carried out in order to elucidate the taxonomic relationship among 17 species belonging to Paris. Eighteen characters including 10 morphological, 4 pollen morphological, 2 cytotalonomical and 2 habitat characters were used for the analysis. On basis of UPGMA clustering analysis, two subgenus and seven groups were recognized. The classification of the two subgenus was different from the opinion of subgenus Daiswa and subgenus Paris by Li Heng. The classification of sect. Dunnianae, sect. Axiparis and sect. Paris was correspondence with the classification of Li Heng. But sect. Fargesianae, sect. Marmoratae and sect. Thibeticae which were established based on the especially characters by Li Heng were put into cluster 2, cluster 3 and cluster 4.

Flavone and steroid chemical constituents from rhizome of Paris axialis / 中国中药杂志

<p><b>OBJECTIVE</b>To study the chemical constituents from the rhizome of Paris axialis.</p><p><b>METHOD</b>The compounds were isolated by column chromatography with silica gel and purified by Sephadex LH-20 column chromatography and preparative RP-HPLC. The structures were identified by means of spectroscopic methods.</p><p><b>RESULT</b>Fourteen compounds were isolated from the EtOAc extract and the n-BuOH extract of P. axialis. Their structures were identified as daucosterol (1), stigmasterol-3-O-beta-D-glycopyranoside (2), beta-ecdysterone (3), pennogenin-3-O-alpha-L-arabinofuranosyl (1 --> 4) -[alpha-L -rhamnopyranosyl (1 --> 2)] -beta-D-glycopyranoside (4), diosgenin-3-O-alpha-L- rhamnopy-ranosyl (1 --> 4) -alpha-L-rhamnopyranosyl (1 --> 4) [alpha-L-rhamnopyranosyl (1 --> 2)] -beta-D-glycopyranoside (5), kaempferol (6), rutin (7), myrincitrin (8), 4, 2', 4'-trihydroxychalcone (9), isorhamnetin-3-O-beta-D- glycopyranoside (10), isorhamnetin-3-O-alpha-L-rhamnopyranosyl (1 --> 2) -beta-D-glycopyranoside (11), isorhamnetin-3-O-beta-D-glucpyranosyl (1 --> 6) -beta-D-glycopyranoside (12), kayaflavone (13), amentoflavone (14).</p><p><b>CONCLUSION</b>Compounds 1-3 and 6-14 are isolated from P. axialis for the first time; and compounds 7-10, 13, 14 are isolated from the genus Paris for the first time.</p>

Chemical constituents from herbs of Paris verticillata / 中国中药杂志

<p><b>OBJECTIVE</b>To study the chemical constituents in herbs of Paris verticillata.</p><p><b>METHOD</b>The compounds were isolated by column chromatography with silica gel and purified by Sephadex LH-20 and RP-HPLC. The structures were identified by means of NMR analysis.</p><p><b>RESULT</b>Nine compounds were isolated from the EtOAc extract and the n-BuOH extract of P. verticillata. Their structures were identified as beta-sitosterol (1), stigmasterol (2), daucosterol (3), beta-ecdysterone (4), 4-hydroxymethyl-gamma-butyrolactone (5), diosgenin-3-O-alpha-L-arabinofuranosyl (1-->4)-[alpha-L-rhamnopyranosyl (1-->2)]-beta-D-glycopyranoside (6), pennogenin-3-O-alpha-L-arabinofuranosyl(1-->4)-beta-D-glycopyranoside (7), pennogenin-3-O-alpha-L-arabinofuranosyl (1-->4)-[alpha-L-rhamnopy-ranosyl (1-->2)]-beta-D-glycopyranoside (8), and pennogenin-3-O-alpha-L-rhamno-pyranosyl (1-->4)-alpha-L-rhamnopyranosyl (1--4)-[alpha-L-rhamnopyranosyl (1-->2)]-beta-D-glycopyranoside (9).</p><p><b>CONCLUSION</b>Compounds 1-9 are isolated from P. verticillata for the first time, and compounds 3, 5 are isolated from the genus Paris for the first time. The compounds 6-9 showed certain inhibition activeness of LA-795 cells, especially, the effects of compounds 6, 8 and 9 were more significant.</p>
