RESUMEN
Meconopsis horridula is one of alpine plants belonging to family Papaveraceae, mainly distributed in Himalaya Range area. M. horridula is a rare alpine flower, and is a kind of traditional Tibetan medicine, which has been included in more than 40 compound formulae, having efficacies of clearing away heat and alleviating pain, activating blood circulation to remove stasis, traditionally used for the treatment of fractures, injuries, and chest and back pains. Modern research shows that the whole plant of M. horridula contains alkaloids, flavonoids, and terpenes, and its pharmacological activities including antitumor, antivirus and myocardial protection etc. However, due to various factors, the current research of M.horridula still faces many challenges. This paper summaries herein a progress of MH on its ecological resources, traditional uses, and studies on chemical constituents and pharmacological effects, hopefully to provide a useful reference for the ecological protection and applications.
RESUMEN
Objective: To identify the common Tibetan traditional medicine of Meconopsis Vig. using nuclear gene internal transcribed spacer (ITS) and chloroplast psbA-trnH sequence. Methods: Ethnopharmacological study was carried out, three species of Ou-Bei (M. torquata, M. punicea, and M. integrifolia) and two species of Cai-Wen (M. racemosa and M. horridula) were collected. The ribosomal DNA ITS and chloroplast psbA-trnH noncoding region sequences were determined and analyzed. Results: The ITS sequences of M. racemosa and M. horridula were completely the same, while variable site could be detected in each pairwise comparison of ITS sequences in other species; The psbA-trnH sequence analysis showed that the variable sites could be detected in each pairwise comparison of the sequences. The combination of them could be used to identify all the five species. Conclusion: The combination of ITS and psbA-trnH sequence could be used to identify the Tibetan traditional medicine Ou-Bei and Cai-Wen in Meconopsis Vig.
RESUMEN
Meconopsis horridula is one of the eight most famous flowers in Chinese province of Yunnan. In this study, a modified biotin-streptavidin capture method was used to detect 13 microsatellite markers in the genome of M. horridula. The polymorphism of each locus was assessed in 24 samples collected from four populations. The number of alleles per locus ranged from 2 to 7 (mean: 3.2). The observed and expected heterozygosities ranged from 0.0833 to 0.9167 and 0.0816 to 0.8050, respectively. Additionally, nine of the 13 microsatellite markers were successfully amplified in three other congeneric species. These polymorphic SSR markers could be useful for studying the population genetics of M. horridula and for assessing genetic variation in this and congenerc species in conservation programs.
