Pharmacokinetic comparison of seven major bioactive components in normal and depression model rats after oral administration of Baihe Zhimu decoction by liquid chromatography-tandem mass spectrometry.[Pubmed:28987996]
J Pharm Biomed Anal. 2018 Jan 30;148:119-127.
A simple and rapid liquid chromatography-tandem mass spectrometry method was firstly developed for simultaneous quantification of neomangiferin, mangiferin, regaloside A, Regaloside I, timosaponin BII, anemarsaponin E and timosaponin AIII in rat plasma after oral administration of Baihe Zhimu decoction, which plays an important role for the treatment of depression. The plasma samples were pretreated by a one-step direct protein precipitation with methanol. Separation of the seven components and scutellarin (IS) from endogenous components with high selectivity and sensitivity (LLOQ, 0.1-1.0ng/mL) was achieved within 10min using Poroshell 120 EC-C18 column (150mmx3.0mm, 2.7mum). A gradient mobile phase consisting of acetonitrile and water (containing 5mM ammonium acetate) was applied at a flow rate of 0.4mL/min. Detection and measurement were performed on an AB Sciex QTRAP((R)) 5500 mass spectrometer in multiple reactions monitoring mode. The intra- and inter-day precisions were all within 15% and the accuracies were in the range of -10.4% to 14.5%. The recovery ranged from 90.8 to 113.8%. The validated method was successfully applied to pharmacokinetic study of the seven components in normal and chronic unpredicted mild stress-induced depression model rats.
Morphological change of skin fibroblasts induced by UV Irradiation is involved in photoaging.[Pubmed:27539902]
Exp Dermatol. 2016 Aug;25 Suppl 3:45-51.
Human dermal fibroblasts (HDFs) are typically flattened or extensible shaped and play a critical role in the metabolism of extracellular matrix components. As the properties of fibroblasts in the dermis are considered to be influenced by their morphology, we investigated the morphological changes induced in fibroblasts by ultraviolet (UV) irradiation as well as the relationship between these changes and collagen metabolism. In this study, we showed that UVA exposure induced morphological changes and reduced collagen contents in HDFs. These morphological changes were accompanied a reduction in actin filaments and upregulation of the actin filament polymerization inhibitor, capping protein muscle Z-line a1 (CAPZA1). External actin filament growth inhibitors also affected the shape of HDFs and reduced collagen levels. These results suggest that UVA exposure may inhibit the polymerization of actin filaments and induce morphological changes in skin fibroblasts. These morphological changes in fibroblasts may accelerate reductions in collagen synthesis. This mechanism may be one of the processes responsible for collagen reductions observed in photoaged skin. When natural materials that suppress these morphological changes in HDFs were evaluated, we found that an extract of Lilium 'Casa Blanca' (LCB) suppressed UVA-induced alterations in the shape of HDFs, which are typically followed by inhibition of collagen reduction. An analysis of the active compounds in LCB extract led to the identification of Regaloside I, which had a structure of phenylpropanoid glycerol glucoside, as the active compound inhibiting the upregulation of CAPZA1. Therefore, inhibition of UVA-induced morphological changes in HDFs is considered to be promising way for the suppression of collagen reduction in photoaging.
