Khảo sát hàm lượng flavonoid toàn phần trong dược liệu thỏ ty tử và vị thuốc thỏ ty tử chích muối bằng phương pháp đo quang

A spectrometric method was established to determine total flavonoid content in crude and salt-processed semen Cuscutae, with a good linearity, precision, and stability. The detection wavelength was set at 510 nm, and an extraction solvent was optimized. This method is apllied to quantify the content of total flavonoid in samples of semen Cuscutae, which were purchased at several markets and traditional medicine clinics (Phu Tho province). The results showed that the contents of flavonoids in salt-processed products accounted for 7.80 – 11.32 mg/g lower than in crude materials (12.48 – 17.29 mg/g). It was understood that the contents of flavonoids were reduced during salt processing.

Keywords: Semen Cuscutae, total flavonoid, spectrometric method.
