Epicuticular wax of four species of Chionochloa

Phytochemistry, 1983
Abstract Shoot epicuticular wax of four species of Chionochloa contained esters (21–38 %); alkanes (15–29%); aldehydes (4–13%); alcohols (8–16%) and acids (1–5%). The major carbon chain lengths ranged from C 24 to C 32 in the acids, alcohols and aldehydes and C 29 and/or C 31 in the alkanes.

Alkanes of foliar epicuticular waxes of velloziaceae

Phytochemistry, 1989
Abstract One hundred and ten species of Velloziaceae were surveyed for the distribution of the alkanes in their foliar epicuticular waxes. Longer chains were found in waxes of representatives of subfamily Barbacenioideae, the main homologues being mostly n -C 33 or n -C 35 except most members of Pleurostima , which had n -C 31 or n -C 33 the

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

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

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 waxes of two sorghum varieties

Phytochemistry, 1978
Abstract The epicuticular waxes of the two sorghum varieties Alliance A and SD 102 have been analyzed, after separation of the leaf blades from the sheaths. The major constituents were found to be free fatty acids but small amounts of esters, aldehydes, alcohols, n -alkanes and sterols were also detected. The typical chain lengths of aldehydes, free

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.

Seed epicuticular wax of avena sativa

Phytochemistry, 1985
Abstract The main fractions in oat seed wax are β-diketones (15.5%), alkanols (14.4%), hydroxy-β-diketones (12.2%), esters (11.1%) and fatty esters (7.2%).

Effect of the Epicuticular Waxes of Fruits and Vegetables on the Photodegradation of Rotenone

Journal of Agricultural and Food Chemistry, 2004
The effect of epicuticular waxes extracted from fruits (apple, nectarine, pear, and plum) and vegetables (tomato and eggplant) on the photodegradation of rotenone was studied. The waxes affected the decay rate and the degradation pathway of this botanical insecticide.
