Triterpenoids in Epicuticular Waxes

1989
All aerial organs of higher plants are covered primarily with a thin continuous wax layer. These surface or epicuticular waxes consist of a very complex mixture of different components. In most cases these very long chained lipids are found in form of homologous series.

Evidence for Surfactant Solubilization of Plant Epicuticular Wax

Journal of Agricultural and Food Chemistry, 2001
The solubilization of isolated, reconstituted tomato (Lycopersicon esculentum Mill.) fruit and broccoli (Brassica oleracaea var. botrytis L.) leaf epicuticular waxes (ECW) by nonionic octylphenoxypolyethoxy ethanol surfactant (Triton X-100) was demonstrated in a model system by TLC and fluorescence analysis using pyrene as a fluorescent probe.

Epicuticular wax variation in ecotypes of Arabidopsis thaliana

Phytochemistry, 1997
Quantification of the epicuticular wax from the stems of 40 ecotypes of Arabidopsis thaliana showed a two-fold range in total wax load that was not correlated to known abiotic characteristics of the ecotype's origin of collection. Chemical analysis of these ecotypes revealed similar epicuticular wax profiles for all ecotypes except CT-1.

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.

Nanostructure of epicuticular plant waxes: Self-assembly of wax tubules

Surface Science, 2009
Abstract A “surface science approach” is used to investigate the growth process of tubular wax structures on plant leaves: natural epicuticular wax from nasturtium leaves, mainly consisting of (S)-nonacosan-10-ol, has been recrystallized on artificial substrates of different structure and polarity, namely HOPG, glass and silicon oxide, and the growth

Epicuticular waxes of four eragrostoid grasses

Phytochemistry, 1984
Abstract The major components of Sporobolus airoides wax were hydrocarbons (37%, C 27 –C 33 ), those of Bouteloua curtipendula and Eragrostis trichoides waxes esters (28% and 31%, respectively) and those of Muhlenbergia wrightii wax free alcohols (57%, almost entirely C 28 ). Free alcohols formed 22% of the wax from B. curtipendula , 19 % of

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.

Rainfall Removes Epicuticular Waxes from Isocoma Leaves

Botanical Gazette, 1987
Amounts of epicuticular waxes on leaves of common goldenweed (Isocoma coronopifolia) and Drummond's goldenweed (I. drummondii) were determined gravimetrically before and after natural rainfall in a nursery and simulated rainfall in the glasshouse. In the nursery, fall rains of 3.3-4.1 cm after a summer with little rainfall removed almost half of the ...

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%).
