Correlative Analysis on the Biomass and Effective Components Contents in Root Tuber of Wild Sichuan Ophiopogon japonicus from Santai County

摘要(Abstract):

[Objective]To study the accumulation of photosynthetic products,the contents of effective components in different grades of root tubers of wild Sichuan Ophiopogon japonicus ( Thunb. ) Ker-Gawl. from Santai County,as well as the eigenvalues of accumulation and their correlative laws. [Method]Wild Sichuan O. japonicus were collected from the hilly region of its main producing areas; and its roots were graded. Then the contents of water extracts,polysaccharides and flavonoids were detected,respectively,by the method in Chinese Pharmacopoeia,phenol-sulfuric acid method and UV method. The correlative laws of root tuber biomass with the contents of water extracts x1,polysaccharides x2 and flavonoids x3 were analyzed. [Result]Both the sensory qualities and the water extracts content of O. japonicus root tubers met the requirements in Chinese Pharmacopoeia ( 2010 edition) ; the dry matter accumulation in the roots of wild plants showed an extremely significant positive correlation with water extracts,polysaccharides content and accumulation,and flavonoids accumulation( P <0. 001***) . However it was negatively correlated with the flavonoids content ( P <0.001***) . [Conclusion]The root tuber of wild Sichuan O. japonicus from Santai County had excellent quality and characters; research on this good germplasm resource provided scientific basis for the resources development and quality evaluation of wild Sichuan O. japonicus from Santai County.
