Three phenylpropanoid glycosides named ningposides A (3-O-acetyl-2-O-feruloyl-alpha-L-rhamnopyranose), B (4-O-acetyl-2-O-feruloyl-alpha-L-rhamnopyranose) and C (3-O-acetyl-2-O-p-hydroxycinnamoyl-alpha-L-rhamnopyranose) along with the known compounds sibirioside A, cistanoside D, angoroside C, acteoside, decaffeoylacteoside and cistanoside F were obtained from the roots of Scrophularia ningpoensis.
Three new minor iridoids were isolated from the roots of Scrophularia ningpoensis. They were elucidated as 8-Oferuloylharpagide, 8-O-(2-hydroxy-cinnamoyl)harpagide and 6-O-a-D-galactopyranosylharpagoside. # 1998 Published by Elsevier Science Ltd. All rights reserved.

The bioactive component harpagoside was successfully separated from the crude extract of Scrophularia ningpoensis Hemsley by one-step purification using high-speed counter-current chromatography (HSCCC). A two-phase solvent system containing n-butanol:ethyl acetate:water (1:9:10) was selected following consideration of the partition coefficient of the target compound. A 276 mg quantity of the c...

To investigate the effect of sheep dung on soil carbon (C) sequestration, a 152 days incubation experiment was conducted with soils from two different Inner Mongolian grasslands, i.e. a Leymus chinensis dominated grassland representing the climax community (2.1% organic matter content) and a heavily degraded Artemisia frigida dominated community (1.3% organic matter content). Dung was collected...
AIM To investigate the antioxidative activity of the constituents of the roots of Scrophularia ningpoensis (Chinese name: Xuanshen). METHODS The main compounds from the roots of Scrophularia ningpoensis were isolated and identified by chromatography and FABMS, NMR etc. Using the techniques of pulse radiolysis, the electron transfers from iridoid glycosides (IG) or phenylpropanoid glycosides (...
Background: Numerous plants in traditional practices of medicine have been used to treat cognitive disorders, including neurodegenerative diseases such as Alzheimer’s disease (AD) and other memory related disorders. Materials and Methods: We present here the evaluation of acetylcholinesterase (AChE) inhibitory and antioxidant activities of the aqueous methanol extracts of five traditional medic...
The aim of current study is to show phenolics, antioxidant capacities and antimicrobial activities seeds five Salvia L. (S. frigida Boiss., S. candidissima subsp. Vahl., virgata Jacq., verticillata var. russellii Benth.) taxa grown in Turkey. flavonoid phenolic acid contents were measured by using HPLC whilst the determined different methods. In addition, agar well diffusion method was used det...
