Role of anthocyanin metabolic diversity in bract coloration of Curcuma alismatifolia varieties.

Plant physiology and biochemistry : PPB
Anthocyanins are one of the key metabolites influencing the coloration of ornamental bracts in plants. Curcuma alismatifolia is an emerging ornamental plant, known for the rich diversity in the coloration of its bracts and the variety of anthocyanins ...

Airway Reactivity and Cotton Bract-Induced Bronchial Obstruction

Chest, 1985
Most seemingly healthy persons challenged with an aerosol of cotton bract extract develop some degree of bronchospasm. The role of nonspecific reactivity of the airways in this reaction to cotton bract extract is undefined. We examined the relationship between airway responses to cotton bract extract and to methacholine, as well as between airway ...

Analysis of the barley bract suppression gene Trd1

Theoretical and Applied Genetics, 2012
A typical barley (Hordeum vulgare) floret consists of reproductive organs three stamens and a pistil, and non-reproductive organs-lodicules and two floral bracts, abaxial called 'lemma' and adaxial 'palea'. The floret is subtended by two additional bracts called outer or empty glumes.

Bronchial Responsiveness after Inhalation of Cotton Bract Extract

American Review of Respiratory Disease, 1988
This study examined nonspecific airway responsiveness to methacholine (MC) after inhalation of cotton bract extract (CBE). In a randomized double-blind, crossover trial, 13 healthy volunteers underwent an MC inhalation challenge test prior to inhalation of CBE and normal saline solution (NSS) aerosol sham as well as 2, 8, 24, and 168 h (7 days) later ...

Safety evaluation of polyphenols extracted from hop bracts

Food and Chemical Toxicology, 2007
Hop bract polyphenols contain polyphenols as promising functional ingredients. To assess the safety of topical hop bract polyphenols, Hopsphenon, we examined acute, 14-day, 28-day and 90-day toxicity tests in rats, and mutagenicity tests using Ames test and micronucleus test in mice.
