Objective: To investigate the inhibitory effects of phenylethanoid glycosides (PhGs) derived from cistanche on melanogenesis in cultured human epidermal melanocytes, and explore the structure-activity relationship through comparison of the inhibitory effect of ten kinds of PhGs. Methods: L-dopa assay was performed to examine the effect of PhGs on tyrosinase activity. Alkaline lysis method was u...
Phenylethanoid glycosides (PhGs), a class of polyphenolic compounds, are considered one of major bioactive constituents of Cistanche deserticola Y.C. Ma (CD), whose extract is orally used in traditional Chinese medicine. Although previous pharmacological studies have reported that PhGs exert many activities, their intestinal transport profiles have not been clarified. In this study, we investig...
The most important components of Plantago lanceolata L. leaves are catalpol, aucubin, and acteoside (=verbascoside). These bioactive compounds possess different pharmacological effects: anti-inflammatory, antioxidant, antineoplastic, and hepatoprotective. The aim of this study was to protect Plantago lanceolata extract from hydrolysis and to improve its antioxidant effect using self-nano-emulsi...
A simple, rapid and specific method was developed to separate as well as to determine the four phenylethanoid glycosides (PhGs) (echinacoside, tubuloside B, acteoside and isoacteoside) in rat plasma after oral administration of Cistanche salsa extract by reversed phase high performance liquid chromatography using a microemulsion as the mobile phase. The separations were performed on a Zorbax Ex...
Oral mucositis (OM) is a common and painful complication of radiotherapy for head and neck cancer. Hangeshashinto (HST), a Japanese traditional medicine, is known to alleviate radiotherapy- and/or chemotherapy-induced OM; however, the detailed mechanism has not yet been clarified. The aim of the present study was to clarify the details of the antioxidative functions of HST against reactive oxyg...
Cistanche deserticola (CD) is one of the two authoritative source plants of Cistanches Herba, a well-known medicinal plant. Herein, 1H NMR spectroscopy was employed to characterize the chemical profile and to distinguish the different parts, as well as to propose a new processing workflow for CD. Signal assignment was achieved by multiple one and two dimensional NMR spectroscopic techniques in ...
Verbascoside (acteoside), a phenyl propanoid glycoside, comprises 0.5 to 3.5 % dry weight of Lippia citriodora leaves. A wide range of biological activities are attributed to verbascoside including anti-inflammatory, antioxidant, anti-bacterial, anti-tumor, anti-fungal, photoprotective as well as chelating effects. The objective of this study is to evaluate the effect of verbascoside on pregnan...
