ABSTRACT
Objective: To study the dissolving yield and ratio fluctuation of Sparganii Rhizoma effective composition groups, including total flavonoids, total alkaloid, and active Al3+, when processed with different vinegar processing technologies. Methods: L9(34) orthogonal test design was used with acetic acid content (A), vinegar ratio (B), soaking time (C), and frying temperature (D) as influencing factors. The differences of dissolving yield and ratio of 80% methanol extract, total flavonoids, total alkaloid, and active Al3+ of processed Sparganii Rhizoma under different vinegar processing technologies were compared. Results: Compared with crude Sparganii Rhizoma, the processed products with a little acetic acid had enhanced the dissolving yield of 80% methanol extract. Moreover, the processed Sparganii Rhizoma with vinegar had effectively enhanced the dissolving yield and ratio of total flavonoids, total alkaloid, and active Al3+. The dissolving yield and ratio of total flavonoids were greatly impacted by frying temperature. Meanwhile, the alkaloid dissolving yield and ratio were most influenced by acetic acid content. The products processed with abundant acetic acid had obviously reduced the dissolving yield of 80% methanol extract, but had increased the alkaloid and active Al3+ dissolving ratio in the extract. Conclusion: The processed Sparganii Rhizoma with vinegar could obviously affect the dissolving yield and ratio of different pharmacodynamic compositions in Sparganii Rhizoma. Suitable processed products should be adopted when Sparganii Rhizoma is used in the different treatments.
