The first investigation of the phytochemical profile of the flowers of Croton krabas led to the isolation of two new clerodane diterpenes, 6S-crotocaudin (1) and crotocaudin B (2), together with two known clerodanes, 6S-crotoeurin C (3) and isoteucvin (4)

Chemistry &Biodiversity, Volume 22, Issue 11, November 2025.ABSTRACT In this paper, the first phytochemical analysis on Teucrium chamaedrys subsp. gracile was reported. The dried aerial parts collected in Algeria were studied, and the analysis was conducted using different techniques: gas chromatography/mass spectrometry (GC/MS) for the fatty acid content, headspace solid‐phase microextraction‐GC‐MS for the ...

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 661-673, July 2025.Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.

Investigations into the total synthesis of insect antifeedant clerodanes
, 1982 Among the still growing group of clerodane type diterpenes, those compounds possessing insect antifeedant activity have drawn much attention.Surprisingly, at the beginning of our investigations, only a few attempts towards the total synthesis of ...
