| Abstract: | Total flavonoid content in Rabdosia lophanthoides was determined by VIS and UV Spectrophotometry,both with rutin as reference sample. In VIS spectrophotometric analysis,(Al(NO_3)_3) was used as the revealing agent and the measurement was conducted at 510 nm.In UV spectrophotometric analysis,the measurement was canducted at 359 nm.The comparation of two methods indicated that UV spectrophotometry was a better method for the determination of the total flavonoid content in Rabdosia lophanthoides. |
