Rotenoids from Boerhaavia diffusa as Potential Anti-inflammatory Agents

, 2016
Five new (2, 3, 5, 7, and 9) and four known rotenoids (1, 4, 6, and 8) were isolated from a methanol extract of Boerhaavia diffusa roots. The structures of the new rotenoids were elucidated by spectroscopic data interpretation. The 70% ethanol extract, a

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, Volume 82, Issue 9, Page 9240-9248, September 2026.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

Food Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...
