Title
Azulenes in cells of allelopathic plants species in arid biocenosis
Victoria V. Roshchina; Anton A. Abushin Allelopathy Journal 2026. doi:10.26651/allelo.j/2026-68-2-1587
Other claims from this paper (6)
- Observation Prolonged 24 h extraction indicated the presence of azulenes inside the cells of leaves of the allelopathic medicinal species of the arid zone of Kalmykia.
- Observation Azulene pigments were found in large amounts in all extraction samples, characteristic of the highest ultraviolet insolation and salt-enriched habitats.
- Observation Azulenes were observed in 10-day old seedlings of some of the plants studied, mainly on the leaf surface.
- Observation Microspectrophotometry showed azulenes on the surface of intact cells with absorption maxima in the region of 570-630 nm, confirmed by spectral analysis of ethanol and acetone extracts.
- Intervention effect Synthetic azulene and purified azulene fractions from several plants decreased the vitality and germination of pollen of Hibiscus sp.
- Intervention effect Synthetic azulene and purified azulene fractions from several plants decreased the vitality and germination of Equisetum arvense vegetative microspores.
