As a part of the search for biologically active plant products, M cells, which form a collagen fiber network in vitro after a prolonged culture period, were used. The n-BuOH-soluble fraction of a methanol extract of leaves of Premna subscandens exhibited promotion of collagen network formation by M cells. Extensive isolation work guided by a bioassay afforded a phenylethanoid, acteoside, as an ...

Reactive oxygen species leads to some diseases associated with oxidative stress. Callicarpa kwangtungensis Chun (CK) is a common remedy in traditional Chinese medicine and possesses diverse biological activities involving antioxidant properties; its main compounds phenylethanoid glycosides (PG) and flavonoids are always reported as antioxidants. In order to develop CK as a safe and activated an...

Wu-Chia-Pi medicated wine, composed nine Chinese medicines soaked in 35% alcohol, is widely used in Asia for its health-promoting functions. However, long-term consumption of alcohol could result in liver dysfunction. In this study, Wu-Chia-Pi solution (WCPS) and extract (WCPE) were prepared by modification of the principals given by the Committee on Chinese Medicine and Pharmacy in Taiwan. The...

The aim of the work was to determine the interactions of a set of anti-cancer compounds with bovine serum albumin (BSA) using a ProteOn XPR36 array biosensor and molecular docking studies. The results revealed that a total of six anti-cancer compounds: gallic acid, doxorubicin, acteoside, salvianolic acid B, echinacoside, and vincristine were able to reversibly bind to the immobilized BSA. The ...

AIM: Colon cancer is one of the main health problems worldwide. Cancer stem cells (CSCs) are referred to as tumor-initiating involved in tumor heterogeneity and dormancy. CSCs can cause drug resistance, metastasis, recurrence primary metastatic cancers. The interactions survival trends colon with other may be an alternative route for effective treatment. In our study, we aimed evaluate effects ...

The antioxidant synergistic effects of Osmanthus fragrans flowers with green tea were evaluated, and their major antioxidant compounds contributed to the total amount of synergy were determined. The antioxidant compounds in O. fragrans flowers with green tea were identified by LC-MS and quantified by UPLC-PDA. The synergistic antioxidant interactions between O. fragrans flowers with green tea a...

Following a constituent enrichment step on a silica gel column, four phenyl-ethanoid glycosides were successfully isolated from Cistanches deserticola and purified by preparative high-speed counter-current chromatography (HSCCC) with a two-phase solvent system composed of ethyl acetate-n-butanol-ethanol-water (40:6:6:50, v/v/v/v). A total of 30.9 mg acteoside, 13.0 mg isoacteoside, 12.5 mg syri...

A new natural compound, named 6-O-(3",4"-dimethoxycinnamoyl) catalpol, was isolated from the defatted alcoholic extract of the flowering parts of Buddleja asiatica Lour. (family Scrophulariaceae). Other separated known compounds included steroids (beta-sitosterol, stigmasterol, stigmasterol-O-glucoside, beta-sitosterol-O-glucoside), iridoid glucosides (methyl catalpol, catalpol, aucubin), pheny...
