During our phytochemical investigation of Haplophyllum villosum (Rutaceae), a perennial herb from Iran, a new 4,8-diaryl-3,7-dioxobicyclo-(3,3,0)-octane type lignan, eudesmin A (1), together with four known compounds--eudesmin (2), haplamine (3), umbelliferone (4) and scopoletin (5)--were isolated from aerial parts of the plant. The structures of the compounds were elucidated using NMR spectral...

Background: Alzheimer’s disease (AD), a progressive neuropsychiatric disorder, is characterized by neuroinflammation, β-amyloid plaques and neurofibrillary tangles. It has been demonstrated that systemic inflammation neuroinflammation caused lipopolysaccharide (LPS) injections in rodents leads to elevation Aβ levels neuronal cell death, finally resulting cognitive impairment.
 Methods: Ani...

PURPOSE The objective of this study was to evaluate the relaxant effect of scoparone from Artemisia capillaris on rabbit penile corpus cavernosum smooth muscle (PCCSM) and to elucidate the mechanism of action of scoparone for the treatment of erectile dysfunction (ED). MATERIALS AND METHODS PCCSM that had been precontracted with phenylephrine was treated with 3 Artemisia herbs (A. princeps, A...

The HPLC-SPE-NMR technique was used for the analysis of a root-bark extract of Croton membranaceus. The components of the extract were separated on an analytical-size reversed-phase HPLC column, the chromatographic peaks were trapped on SPE (solid-phase extraction) cartridges after post-column dilution of the eluate with water and the compounds were eluted from the cartridges with acetonitrile-...

In this study the leaves of the Thai noni/Yor, (Morinda citrifolia Linn.) were extracted by several methods and evaluated against human cancer cell lines: KB (human epidermoid carcinoma), HeLa (human cervical carcinoma), MCF-7 (human breast carcinoma) and HepG2 (human hepatocellular carcinoma) cell lines as well as a Vero (African green monkey kidney) cell line, employing the MTT colorimetric m...

A new natural coumarin, angepubebisin (1), and a new furan, angepubefurin (2), together with the five known compounds, umbelliferone, angelol B (3), ulopterol (4), peucedanol (5), and scopoletin, were isolated from the roots of Angelica pubescens Maxim. f. biserrata Shan et Yuan. The structures of angepubebisin (1) and known compounds were determined by spectroscopic methods, including IR, UV, ...
