Abstract: Objective To clarify the correlation between the characters and microscopic characteristics of Polygonum multiflorum Thunb. and its quality, and establish a method to evaluate the quality. Methods The history and basal traits of Polygonum multiflorum Thunb. were studied based on related literature and books. The correlations between the trait characteristics of “red and white” Polygonum multiflorum Thunb., cloudy pattern, wood center and its quality were explored. Results The authentic basal root of Polygonum multiflorum Thunb. should be Polygonum multifonum Thunb. of the family Polygonaceae. The wood center of Polygonum multiflorum Thunb. referred to the round-shaped central part or the central formation of the layer ring in the cross-section of the herb. There was a correlation between the cloudy pattern and wood center and the quality of Polygonum multiflorum Thunb. Herbs with an obvious cloudy pattern but no wood center had higher contents of effective ingredients while those with a small or no cloud pattern but with a wood center had lower contents. Conclusion The categorization of Polygonum multiflorum Thunb. into “red and white” types remains controversial.Studies are so far insufficient to definitively correlate traits with the quality of Polygonum multiflirum Thunb., so in-depth research is needed in this area.
