Anthocyanins scavenge harmful reactive oxygen species (ROS), and may provide antioxidative protection within plant cells. For the shade species Elatostema rugosum A. Cunn., it was recently established that red-leaved morphs held a significant antioxi

The incomplete structure proposed in 1972 for a unique "flavone-polysaccharide" compound, MF-1, from the liverwort Monoclea forsteri, has been re-examined. Rather than the proposed 8-methoxyluteolin structure with polysaccharides attached to the 7- a

Variation in morphology and flavonoid chemistry is appraised in populations of Hebe pimeleoides. An infraspecific classification is proposed for H. pimeleoides, wherein two subspecies are recognised. Subspecies pimeleoides occurs from south‐east Ne

The 5,7-dihydroxyisoflavones do not emit detectable fluorescence and are significantly more photostable than the two 7-hydroxy-5-deoxyisoflavones, daidzein and formononetin. The latter isoflavones emit fluorescence that depends on the basicity of the

This study used comparisons across nine populations of Trifolium repens (white clover) in conjunction with drought to examine physiological responses to ultravioletB radiation (UV-B). Plants were exposed for 12 weeks to supplementation with 13.3 kJ m
