BACKGROUND
Anti-phospholipid syndrome is a thrombogenic and systemic autoimmune disorder that influences fetal life throughout gestation period. Over expression of tissue factor on the surface of monocyte(s) is reported to be a major causative agent in inducing anti-phospholipid antibody-mediated
Phytochemical investigation of air-dried powdered roots of Artemisia monosperma growing in Egypt afforded two new compounds; 6-hydroxy-7,8-dimethoxycoumarin (I) and 5-acetyl-2-[1'-(hydroxymethyl)ethyl]-2,3-dihydrobenzo[b]furan (IV), in addition to the known compounds; 6-hydroxy-5,7-dimethoxycoumarin
The isolation of 6,7-dimethoxycoumarin (1), 6-methoxy-7,8-methylenedioxycoumarin (2), 5,6-dimethoxy-7,8-methylenedioxycoumarin (3), 6-hydroxy-7,8-methylenedioxycoumarin (4) and 5-hydroxy-6,8-dimethoxycoumarin (arteminin) (5) is reported.
OBJECTIVE
To investigate the chemical constituents in flower bud of Artemisia scoparia.
METHODS
The methanol extract was isolated by column chromatography with silica gel, polyamide and Sephadex LH-20 as packing materials and HPLC, six compounds were obtained and their structures were identified by
In perfusion experiments, the acetone extract of Artemisia capillaris buds significantly inhibited the response to norepinephrine of helical strips of rabbit thoracic aorta. The acetone extract was fractionated by column chromatography to identify the active constituent. Kinetic experiments using
Triple negative human breast cancer (TNBC) is an aggressive cancer subtype with poor prognosis. Besides the better-known artemisinin, Artemisia annua L. contains numerous active compounds not well-studied yet. High-performance liquid chromatography coupled with diode-array and mass
Scoparone (6,7-dimethoxycoumarin) is the representative ingredient of Yinchenhao (Artemisia capillaris Thunb.) which is a famous Chinese medicinal herb and shows favorable efficacy for all kinds of liver disease, specifically for the treatment of Yanghuang syndrome (YHS). The precise molecular
OBJECTIVE
Scoparone (6,7-dimethoxycoumarin), a coumarin isolated from a hypolipidaemic Chinese herb Artemisia scoparia, has vasodilator and antiproliferative activities and possesses free radical scavenging properties in vitro. The aim of the study was to investigate the morphological effects of
1. More than 300 coumarins have been identified from natural sources, especially green plants. The pharmacological and biochemical properties and therapeutic applications of simple coumarins depend upon the pattern of substitution. More complex related compounds based on the coumarin nucleus include
A method for the screening and analysis of biologically active compounds in traditional Chinese medicine is proposed. Affinity chromatography using a human serum albumin (HSA) stationary phase was applied to separate and analyze the bioactive compounds from Artemisia capillaris Thunb. Five major
Artemisia annua L. has gained increasing attention for its anticancer activity. However, beside artemisinin, less is known about the possible bioactive ingredients of Artemisia annua and respective herbal preparations. We hypothesized that, in addition to artemisinin, Artemisia annua
