Research progress on characteristics and influencing factors of main active ingredients in Bletillae Rhizoma
Baiji(Bletillae Rhizoma)is the dried tuber of Bletillla striata,a perennial plant in the Orchidaceae family,has great medicinal potential.In order to meet market demand,the artificial cultivation of Bletillae Rhizoma has been increasing in many province and regions of China,the quality of the artificially planted Bletillae Rhizoma is the basic guarantee for the high-quality development of China's Bletillae Rhizoma industry.The quality of Bletillae Rhizoma is mainly determined by effective ingredients such as Bletillae Rhizoma polysaccharide,militarine,and total phenol.By reviewing the distribution characteristics of these components in Bletillae Rhizoma tuber from different provinces,planting years,and ages to discuss the factors that influence the main effective ingredients.Additionally,the medicinal potential of Bletillae Rhizoma's above-ground parts and roots was discussed,and future research on the quality,and cultivation of Bletillae Rhizoma above-ground parts,tuber,and roots was proposed to provide a reference for the wise development and utilization of these resources.
