Bruniales

Bruniales is a small order of flowering plants including Bruniaceae and Columelliaceae, mainly distributed in southern hemisphere temperate regions. Members produce flavonoids, phenolic acids, and triterpenoids, which support adaptation to nutrient-poor and stressful environments. In biomedical research, Bruniales is relatively underexplored but shows potential antioxidant and anti-inflammatory properties. Its restricted diversity and phylogenetic position make it useful for studying specialized evolution in eudicots and niche metabolite diversification.
