ABSTRACT
Objective: Comparison of alkaloid and polysaccharides content in different parts of whole plant of wild aconitum in Nanyang, and to explore the medicinal value of aboveground part and fibrous root of wild aconitum in Nanyang. Methods: The contents of three monoester alkaloids, three diester alkaloids in wild aconitum, radix aconiti carmichaeli, fibrous root and aboveground parts in Nanyang were determined by HPLC method; The content of crude polysaccharides was determined by sulfuric-phenol method, crude polysaccharides content from different tissues of wild aconitum in Nanyang in different harvest time was compared, including wild aconitum in Nanyang, wild radix aconiti carmichaeli in Nanyang, fibrous root, aboveground part. Results: Among the 4 parts of the wild Aconitum in Nanyang, the contents of 3 mono ester alkaloids rang from high to low: wild aconitum in Nanyang＞ wild radix aconiti carmichaeli in Nanyang＞ fibrous root＞ aboveground part (P ＜ 0.05), the contents of three diester alkaloids rang from high to low: wild radix aconiti carmichaeli in Nanyang＞ fibrous root＞ wild aconitum in Nanyang＞ aboveground part (P ＜ 0.05), the order of total alkaloid content from high to low is: wild radix aconiti carmichaeli in Nanyang＞ fibrous root＞ wild aconitum in Nanyang＞ aboveground part (P ＜ 0.05), The content of crudepolysaccharides in different tissues of wild aconitum in Nanyang were in the sequence of wild radix aconiti carmichaeli in Nanyang＞ wild aconitum in Nanyang＞ aboveground part＞ fibrous root (P ＜ 0.05) . Conclusion: In this study, an attempt was made to explore the differences of 6 kind salkaloid content in different parts of whole plant of wild aconitum in Nanyang, which provided scientific basis for the medicinal value of the fibrous roots and the aboveground parts.
