Distribution of Paeonia lactiflora Resources and Quality of Artificial Cultivated Products in Heilongjiang Province
Objective The resource distribution and quality characteristics of artificial cultivated Paeonia lactiflora in Heilongjiang Province are studied to provide reference for promoting its resource development and rational application.Methods The distribution of Paeonia lactiflora in Heilongjiang Province was analyzed through investigation,visits and other methods.Meanwhile,30 batches of Paeoniae Radix Rubra samples from Heilongjiang Province were selected for macroscopic identification,microscopic identification and thin-layer chromatographic identification.Moisture,total ash,extract,sulfur dioxide residue and heavy metals were examined.The contents of paeoniflorin,gallic acid,albiflorin and benzoic acid were detected.Results In terms of resource distribution,wild peony in Heilongjiang Province was mostly distributed in mountainous areas,and artificial cultivated peony was mostly distributed in plain areas.Both of them were distributed in counties along the river,which was the result of the combined action of natural environment and humanistic environment.In terms of quality characteristics,the content range of water,total ash,extract and other indicators of artificial cultivation of Paeoniae Radix Rubra in Heilongjiang Province were clarified,and the content of paeoniflorin was measured to be more than 2.5％.Conclusion This study can provide scientific basis and reference for the development of industry of artificial cultivation of Paeonia lactiflora in Heilongjiang Province and the establishment of its quality standards.
