Secretory Products in Petals of L. Flowers: A Histochemistry, Ultrastructure, and Phytochemical Study of Volatile Compounds.

(1) Background: L. is a medicinal plant whose flowers are widely used in herbal medicine. The aim of the study was to localise flower tissues that are responsible for the production of secretory products in petals and to analyse the volatile compounds.

Histochemical and Phytochemical Analysis of subsp. L. Corolla: Essential Oil, Triterpenes, and Iridoids.

The aim of this study was to conduct a histochemical analysis to localize lipids, terpenes, essential oil, and iridoids in the trichomes of the subsp. corolla. Morphometric examinations of individual trichome types were performed.
