Saffloroside, 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 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...
متن کاملBreeding improvements in safflower (Carthamus tinctorius L.): A review
Safflower (Carthamus tinctorius L.) is an oil seed crop that is grown not only for its edible oil but also for its applications as animal feed and plant-made pharmaceuticals. Historically, biometrical genetics played a crucial role in the improvement of safflower seed yield and its components, phenologic and morphologic traits, and nutritional properties including oil, fatty (linoleic, oleic, s...
متن کاملIsocartormin, 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 کاملInhibitory effects of active compounds isolated from safflower (Carthamus tinctorius L.) seeds for melanogenesis.
In order to develop a new skin whitening agent, safflower (Carthamus tinctorius L.) seeds were evaluated for melanogenesis inhibitory activity and its active principles were identified following activity-guided isolation. The 80% aqueous methanol extract and ethyl acetate fraction from safflower seeds showed a significant inhibition for mushroom tyrosinase. Three active compounds, N-feruloylser...
