New Phenolics from Linum mucronatum subsp. orientale
INTRODUCTION Lignans and flavonoids are widely distributed phenolics in the plant kingdom. Aryltetralin type lignans (podophyllotoxin derivatives) as the major secondary metabolites of Linum species play an important role in the production of chemotherapy drugs. In the present study, lignans and flavonoid glycosides from aerial parts of Linum mucronatum subsp. orientale were isolated and identi...
متن کاملLinum mucronatum: organ to organ lignan variations.
The percentage of podophyllotoxin (PTOX) and its congener lignans were measured by HPLC in Linum mucronatum ssp. mucronatum (Linaceae) fresh plant organs. The highest amounts of PTOX (0.595 +/- 0.060% g/g dry wt) and 6-methoxypodophyllotoxin (MPTOX) (1.491 +/- 0.125% g/g dry wt) were found in the plant sexual organs. Whereas, the highest levels of beta-peltatin, 5'-demethoxy-MPTOX and yatein we...
متن کاملNatural phenolics greatly increase flax (Linum usitatissimum) oil stability
BACKGROUND Flaxseed oil is characterized by high content of essential polyunsaturated fatty acids (PUFA) promoted as a human dietary supplement protecting against atherosclerosis. The disadvantage of the high PUFA content in flax oil is high susceptibility to oxidation, which can result in carcinogenic compound formation. Linola flax cultivar is characterized by high linoleic acid content in co...
متن کاملAccumulation of lignans in suspension cultures of Linum mucronatum ssp. armenum (Bordz.) Davis.
For the first time callus and suspension cultures of Linum mucronatum ssp. annenum were initiated, grown in darkness at 25 degrees C and analyzed for lignans. 6-Methoxypodophyllotoxin was the main lignan besides smaller amounts of podophyllotoxin isolated and identified by chromatographic methods as well as by 1H NMR.
متن کاملNew Phenolics from Baccharis Leaf Exudate
A previous study on the leaf resin composition of some Baccharis species revealed that the resinous material consists mostly of terpenoids, in which more or less lipophilic flavonoid aglycones are dissolved [1]. In B. salicifolia, a major terpenoid was found to be the rare triterpene maniladiol [2]. The major flavonoids were penduletin (6 -hydroxykaempferol3,6 ,7-trimethyl ether) and pinocembri...
