Epicuticular wax of Eragrostis curvula

Phytochemistry, 1982
Abstract Epicuticular wax of Eragrostis curvula contains hydrocarbons (6%), esters (13%), acids (3%), alkanols (4%), tritriacontane-12,14-dione (47%), 5(S)-5-hydroxytritriacontane-12,14-dione (14%) as major components. The esters consist of triterpenol esters (42%) as well as alkanol esters. The free alkanols consist principally Of C16C32 components,

The ketol constituents of Brassica epicuticular waxes

Chemistry and Physics of Lipids, 1977
Abstract The minor ketol constituents of the leaf epicutucular waxes from 4 Brassica species (cabbage, broccoli, cauliflower and rape) were isolated and characterised by chromatographic methods and mass spectrometry. Two classes of ketols, both of which contained two major isomers, were identified in all the waxes, a novel α-ketol fraction ...

Epicuticular wax of Pinus radiata needles

Phytochemistry, 1978
Abstract Epicuticular wax isolated from the cotyledons and primary needles of 10-week-old Pinus radiata seedlings is similar in composition and contains 86% neutral compounds, viz. alkyl esters (25%, C 24 –C 64 ), nonacosan-10-ol (52%), heptacosane-5,10-diol (2%), nonacosane-4,10-diol, nonacosane-5,10-diol, and nonacosane-10,13-diol (total 12%) and

Influence of Epicuticular Waxes on the Photolysis of Pirimicarb in the Solid Phase

Journal of Agricultural and Food Chemistry, 1998
The influence of epicuticular waxes extracted from different fruits on the photodegradation of pirimicarb (I) in the solid phase was studied. Waxes were extracted with CHCl(3) and CHCl(3)/CH(3)OH from nectarines (N), oranges (O(R)), and mandarin oranges (M). All of the waxes affect the qualitative behavior of the photodegradation of I: the formation of

Epicuticular Wax Ultrastructure and Systematics

1994
Based on scanning electron microscopy (SEM) techniques a vast amount of systematically relevant information on the structure and composition of cuticular surfaces has been accumulated (Behnke and Barthlott 1983; Juniper and Jeffree 1983; Barthlott 1990).

Epicuticular wax ultrastructure and classification of Ranunculiflorae

1995
Epidermal surfaces of about 199 species from 66 genera of ranunculiflorous families are examined by scanning electron microscopy. The micromorphology of their epicuticular wax crystals is presented and discussed under taxonomic aspects. All families of the Ranunculiflorae s. str.

Molecular genetics of epicuticular wax biosynthesis

Trends in Plant Science, 1996
The epicuticular wax (EW) layer that coats the outer surface of plants is composed of a variety of long chain length hydrocarbons. Genetic studies indicate that a very large number of genes are involved in wax production. However, the pathway(s) by which the waxes are synthesized and deposited onto the plant surface remain elusive.

Alkane distribution in epicuticular wax of epacridaceae

Phytochemistry, 1983
Abstract Alkane distribution pattern was determined in the epicuticular wax of leaves of 39 species and in the flower wax of three species of Epacridaceae. Uniform patterns were observed within some genera ( Monotoca, Styphelia ) whereas in others no common pattern was apparent.

Epicuticular wax of Agropyron smithii leaves

Phytochemistry, 1976
Abstract Wax on the leaves of Agropyron smithii contains hydrocarbons (3%, C 27 –C 33 ), esters (4%, C 26 –C 56 ), free acids (5%, C 14 –C 36 ), hentriacontane-14,16-dione (17%), 25-oxohentriacontane-14,16-dione (3%), 25-hydroxyhen-triacontane-14,16-dione (30%), 26-hydroxyhentriacontane-14,16-dione (18%) and unidentified material (20%).
