Rapid identification of growth years and profiling of bioactive ingredients in Astragalus membranaceus var. mongholicus (Huangqi) roots from Hunyuan, Shanxi.

ABSTRACT: BACKGROUND:The content of medicinal bioactive constituents in huangqi is affected by plant age. In this study, we devised a quick and convenient method for determining the age of huangqi, which was cultivated in Hunyuan County (Shanxi Province). METHODS:1, 2, 3, 4, 5, 8, 10 growth years huangqi had 38 samples, all samples were collected separately. The growth rings in these samples were observed after making paraffin section and freehand-section. The relationship between growth rings and its growth years was analyzed by SPSS 19.0 software. Histochemical localization of total flavones and saponins in huangqi was determined by color reactions. The concentration of four flavonoids and two saponins in the roots of huangqi of different ages and different organizational structure (normal roots a
