Abstract:
Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.
