Isocartormin, a novel quinochalcone C-glycoside from Carthamus tinctorius
A new semi-quinonechalcone C-glycoside isocartormin along with cartormin and safflomin C were isolated from the water extract of Carthamus tinctorius L. The structure of isocartormin was determined by extensive analysis of HR-MS, 1D- and 2D NMR data, and by comparison with those of cartormin reported previously by our group. Isocartormin was identified as a diastereoisomer of cartormin with a r...
متن کاملSaffloroside, a new flavonoid from flowers of Carthamus tinctorius L
From the flowers of Carthamus tinctorius L., cultivated in Samara Region (Russian Federation) there was isolated a new flavonoid, named us saffloroside, which has the structure of 7-О--Dglucopyranoside of 3, 7, 31, 41-tetrahydroxy-5-methoxyflavone (azaleatin). The chemical structure of saffloroside there was elucidated by means of 1H-NMR-, UV-spectroscopy and mass spectrometry. In the course o...
متن کاملTwo New Quinochalcone C-Glycosides from the Florets of Carthamus tinctorius
Two new quinochalcone C-glycosides, named hydroxysafflor yellow B (1) and hydroxysafflor yellow C (2), along with two known quinochalcone C-glycosides, safflomin C (3) and saffloquinoside C (4), and one known flavanone, (2R)-4',5-dihydroxyl-6, 7-di-O-β-d-glucopyranosyl flavanone (5), were isolated from the florets of Carthamus tinctorius. Their structures were determined by extensive spectrosco...
متن کاملAnti-Thrombotic Effect of Carthamus tinctorius Linn Extracts in Rats
Purpose: To explore the effects of Carthamus tinctorius L. (CTL) extracts on thrombosis in rats. Methods: CTL extract was obtained in hot water (60 C), dried in a hot air oven and then freeze-dried. The rats were divided into 6 groups: normal group, control group, reference group (aspirin 5 mg/kg) as well as groups that received 20, 40 and 80 mg/kg doses of CTL, respectively. For each group, tr...
متن کاملQuality evaluation of safflower (Carthamus tinctorius L.) cultivars
Abstract Safflower is a minor oilseed crop in Australia where the market is dominated by canola, cottonseed and sunflower. Safflower however offers an alternative oilseed crop in marginal areas. This study was designed to evaluate current safflower lines and to determine their potential value both for edible oil and meal for animal feed. Two sets of samples were analysed. The first was a collec...
