High impact information on Magnoliaceae

• The main compounds in headspace of fresh Michelia alba flowers included alpha-myrcene, (S)-limonene, (R)-fenchone, linalool, camphor, caryophyllene, germacrene D, etc., a greater number of compounds than for frozen flowers and withered flowers [1].
• Cytotoxic agents from Michelia champaca and Talauma ovata: parthenolide and costunolide [2].
• This report shows the in vitro antioxidant activity of some fractions isolated from leaves of two Columbian Magnoliaceae, Talauma hernandezii G [3].
• From the ethyl acetate soluble fraction of twigs of Magnolia denudata (Magnoliaceae), seven new neolignan derivatives, 1-7, were isolated along with eighteen known lignan and neolignan derivatives, 8-25 [4].
• Constituents of Michelia Rajaniana. Two new germacranolide amides [5].

Biological context of Magnoliaceae

• The full length gene encoding the D1 protein of photosynthesis (psbA) has been cloned and sequenced from Magnolia pyramidata (Magnoliaceae) [6].

Anatomical context of Magnoliaceae

• The reduction of the contraction elicited by caffeine, an opener of ryanodine-sensitive receptors, suggests that the fraction S4 of Michelia figo leaves could produce the vasorelaxing response by the blockade of ryanodine-sensitive Ca(2+) channels of the sarcoplasmic reticulum [7].

Associations of Magnoliaceae with chemical compounds

• (Magnoliaceae), Citrus aurantium L [8].
• (Magnoliaceae), as well as several purified fractions, showed a concentration-dependent vasorelaxing effect on aortic rings endothelium-deprived and pre-contracted by norepinephrine (NE) [7].
• The methanol extracts of leaves, seeds, stem and root barks, stem and root heart-woods of Michelia champaca and the obtained fractions (petrol, dichloromethane, ethyl acetate, butanol) exhibited a broad spectrum of antibacterial activity [9].
