Epicuticular Wax Alkanes of Scutellaria Lateriflora L. Leaves
The dried aerial parts of scutellaria lateriflora L. (family Labiatae), have been used for many years as a domestic remedy for epilepsy, hysteria, and nervous tension states. Although several phytochemical investigations have been made regarding the constituents present in this species (i. e. flavonoids, iridoids), none has been recorded concerning the cuticular wax. Using thin-layer chroma...
متن کاملEpicuticular Wax Ester of the Leaves of Scutellaria Laterif Lora L.
Subsequent to phytochemical investigation on scutellaria lateriflora (Labiatae) from Mazandaran provincein Iran, the wax ester fraction of the leaves has been investigated. Using TLC, CC GLC and GLC-MS, the alkyl esters of the epicuticular wax was analysed. Total concentration of the esters was 35% and it was shown to be composed of a homologous series having various chain lengths in the ra...
متن کاملUltrastructure of Epicuticular Wax in Canola
U ltrastructure of the epicuticular wax of four commercially grown Canadian cultivars of canola (Brassica campestris cvs. Tobin and Candle, B. napus cvs. Altex and W estar) was investigated. Freeze-drying and air-drying methods of specimen preparation for scanning electron microscopy were compared. The freeze-drying method resulted in disruption and possible washing away of wax crystals, wherea...

متن کاملChemical composition of the epicuticular and intracuticular wax layers on adaxial sides of Rosa canina leaves.
BACKGROUND AND AIMS The waxy cuticle is the first point of contact for many herbivorous and pathogenic organisms on rose plants. Previous studies have reported the average composition of the combined wax extract from both sides of rose leaves. Recently, the compositions of the waxes on the adaxial and abaxial surfaces of Rosa canina leaves were determined separately. In this paper, a first repo...
