Phenylethanoid glycosides from Michelia champaca leaves

Phytochemistry
Chemical investigation on the leaves of Michelia champaca L. (Magnoliaceae) led to the isolation of five previously undescribed phenylethanoid glycosides (PhGs), 4-O-β-d-glucopyranosyl-acteoside (1), 4‴-O-(6-O-E-caffeoyl)-β-d-glucopyranosyl-acteoside (2), 4‴-O-(6-O-E-caffeoyl)-β-d-glucopyranosyl-isoacteoside (3), 6""-O-E-feruloyl-echinacoside (4), and ...

Phenylethanoid glycosides from Prostanthera melissifolia

Phytochemistry, 1999
Abstract Six phenylethanoid glycosides were isolated from aerial parts of Prostanthera melissifolia, together with apigenin and ursolic acid. The glycosides were characterized by spectral methods as martynoside, isomartynoside, verbascoside, isoverbascoside, betonyoside F and isobetonyoside F, the latter being a new natural product.

Synthetic phenylethanoid glycoside derivatives as potent neuroprotective agents

European Journal of Medicinal Chemistry, 2015
Several phenylethanoid glycoside derivatives were designed and synthesized. Most of the synthetic compounds showed significant neuroprotective effects, including antioxidative and anti-apoptotic properties. Specifically, target compounds displayed potent effects against various toxicities such as H2O2 and 6-hydroxydopamine (6-OHDA) in PC12 cells. Among

Antioxidant activity of phenylethanoid glycosides from Brandisia hancei

Journal of Ethnopharmacology, 2000
Brandisia hancei is a medicinal herb in China. The ethanol extract of this plant and four phenylethanoid glycosides, acteoside (1), 2'-acetylacteoside (2), poliumoside (3) and brandioside (4), isolated from it were shown to have inhibitory effects on free radical-induced hemolysis of red blood cells and free radical scavenging activities in vitro ...

Inhibition of Amyloid β Aggregation by Acteoside, a Phenylethanoid Glycoside

Bioscience, Biotechnology, and Biochemistry, 2013
We examined the effects of acteoside (1a), which was isolated from Orobanche minor, and its derivatives on the aggregation of a 42-mer amyloid β protein (Aβ42) in our search for anti-amyloidogenic compounds for Alzheimer's disease (AD) therapy. Acteoside (1a) strongly inhibited the aggregation of Aβ42 in a dose-dependent manner.

A new phenylethanoid glycoside from Incarvillea compacta

Journal of Asian Natural Products Research, 2015
A new phenylethanoid glycoside, 3'''-O-methylcampneoside I (1), was isolated from the 90% ethanolic extract of the roots of Incarvillea compacta, together with three known compounds, campneoside I (2), ilicifolioside A (3), and campneoside II (4). Their structures were determined spectroscopically and compared with previously reported spectral data ...

[Determination of phenylethanoid glycosides in Orobanche coerulescens].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2016
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.
