Investigation on distribution and utilization of Chloranthaceae plants resources in Guizhou Province
The resource of Chloranthaceae is rich,most of which can be used for medicinal purposes.Through the sorting and analysis of the Chloranthaceae plant specimens preserved in the Chinese Virtual Herbarium and related literature,the current status of resources,distribution,altitude,habitat,and utilization of the species in the Guizhou Province region had been understood.The results indicate that there were 2 genera and 12 species of Chloranthaceae in this region area,which were vertically distributed between 150 to 2 300 meters in altitude,with a higher species richness in mid-altitude areas;among them,Sarcandra glabra(Thunb.)Nakai and Chloranthus henryi Hemsl.had a relatively wide distribution,often growing in valleys or on moist slopes at the foot of mountains,with significant differences in associated plants.The Chloranthaceae plants are often described as pungent,bitter,and warm,with slight toxicity,and their efficacy such as detoxifying and relieving pain,dispelling wind and removing dampness and promoting blood circulation and removing blood stasis are more common,commonly being used by ethnic minorities as a regular medication for treating rheumatism,swelling,pain,and traumatic injuries.The research provided a reference for the rational exploration and utilization of Chloranthaceae plant resources.
