Determination of total flavonoids in three Sedum crude drugs by UV-Vis spectrophotometry.

Chen Y, Wang J, Wan D - Pharmacogn Mag (2010)

Bottom Line: A simple, rapid UV-Vis spectrophotometry method for the determination of total flavonoids in Sedum sarmentosum Bunge., S. lineare Thunb., and S. erythrostictum Migo. was developed, with a good linearity, precision, and stability.The detection wavelength was set at 500 nm, and an extraction solvent was optimized.Through the comparative study of multiple samples of the three plant drugs, their collected seasons and the habitats can be preliminarily ascertained, which may help to control the quality of the medicines to some extent.

ABSTRACT
A simple, rapid UV-Vis spectrophotometry method for the determination of total flavonoids in Sedum sarmentosum Bunge., S. lineare Thunb., and S. erythrostictum Migo. was developed, with a good linearity, precision, and stability. The detection wavelength was set at 500 nm, and an extraction solvent was optimized. Through the comparative study of multiple samples of the three plant drugs, their collected seasons and the habitats can be preliminarily ascertained, which may help to control the quality of the medicines to some extent.

Figure 0003: The relationship among month of collection, habitat and the content of total flavonoids in S. sarmentosum Bunge.

Mentions: A relationship between total flavonoid content and harvest season is also revealed by Table 3. All the three plant medicines contained maximum flavonoids in April (flowering period), and then the flavonoid quantities kept decreasing from April to June or July (during this time, the leaves of S. erythrostictum Migo. mostly fell down). But for S. sarmentosum Bunge. and S. lineare Thunb., the contents began to rise a little after August [Figures 3 and 4] (except S. sarmentosum Bunge. sample collected in Wuhan), while the flavonoid quantities of S. erythrostictum Migo. continued to drop during autumn [Figure 5]. It seemed that all the three plant drugs should have the best quality if harvested in flowering time. Thus, the quality could be preliminarily controlled by flavonoid determination.
