“…Absolute configuration of plumericin and isoplumericin from the plant was later on revised on the basis of X-ray crystal structure and Circular Dichroism (CD) spectra (Elsasser et al, 2005). Crude protein, oil, hydrocarbon, polyphenol, saponification value, ash and lignin content of the species were measured to test its efficacy as an alternative energy source (Augustus et al, 2003). Essential oil of the flowers has yielded 2-methylbutan-1-ol, β-phenylethyl alcohol, nanodecane, heneicosane, benzyl salicylate, tetradeconoic acid, octadecanoic acid and phenylacetaldehyde (Sulaiman et al, 2008).…”

Plumeria rubra L. (Apocynaceae) is a deciduous ornamental tree species with fragrant flowers native to Mexico, Central America, Colombia and Venezuela but also cultivated in tropical and subtropical countries. The plant is known to possess biological activities viz., antibacterial, antifungal, antiviral, antialgal, larvicidal, molluscicidal, piscicidal, nematicidal, antioxidative and free radical scavenging, hypolipidemic, proteolytic, cytotoxic, abortifacient activities etc. A number of phyto-constituents are reported from the plant which signifies biological activities and diverse ethnomedicinal uses of this plant species. The present review deals with the literature involving ethnobotany, phytochemistry and pharmacology of the plant.Key words: Plumeria rubra, ethnobotany, phytochemistry, pharmacology, review INTRODUCTIONPlumeria rubra L. (Apocynaceae) commonly known as 'Frangipani' is an ornamental tree species bearing fragrant flowers. The plant is native to Mexico, Central America, Colombia and Venezuela but cultivated in tropical and subtropical countries. The plant is reportedly used in a number of traditional medicinal preparations throughout Asia and Latin America for diabetes, diarrhea, dysentery, intestinal worms, stomach-ache, toothache, earache, eye-cleaning, tongue cleaning, finger nail pain, wound healing, fractures, blisters, sores, subcutaneous mycosis, rabies, malaria, rheumatism, asthma, cancer, birth control, women complaints, lactation, pediatric care, ethnoveterinary (diarrhoea and dysentery and snakebite), piscicidal, offering to god and as ornamental and it is also utilized as part of folk ritual due to its aesthetic values. A number of preclinical pharmacological investigations were performed to elucidate its bioactivities such as antibacterial, antifungal, antiviral, antialgal, larvicidal, molluscicidal, piscicidal, nematicidal, antioxidative and free radical scavenging, hypolipidemic, proteolytic, anticancer, abortifacient properties. A number of phytochemicals have been isolated from the plant, a few of which were correlated with its bioactivity. A systematic compilation on ethnobotanical, phytochemical and pharmacological aspects has been given in this paper.

“…It has been revealed that Artocarpus integrifolia, Euphorbia hirta, E. splendens, and Ficus religiosa contain cispolyisoprene as in the case of NR. 7 It has been reported that the chemical constituents of the rubber from Artocarpus integra latex are composed of 72% resins soluble in acetone and rubber-like residue which is solubilized in petroleum ether and benzene. 8 The low molecular weight rubber isolated from Euphorbia lactiflua latex was chlorinated and found to show comparable properties with chlorinated rubber obtained from liquid NR.…”

Structural Characterization of Rubber from Jackfruit and Euphorbia as a Model of Natural Rubber

et al. 2004

A structural study of low molecular weight rubbers from Jackfruit (Artocarpus heterophyllus) and Painted spurge (Euphorbia heterophylla) was carried out as model compounds of natural rubber from Hevea brasiliensis. The rubber content of latex from Jackfruit was 0.4-0.7%, which is very low compared with that of 30-35% in the latex from Hevea tree. The rubber from Jackfruit latex was low molecular weight with narrow unimodal molecular weight distribution (MWD), whereas that obtained from E. heterophylla showed very broad MWD. The 1H and 13C NMR analyses showed that Jackfruit rubber consists of a dimethylallyl group and two trans-isoprene units connected to a long sequence of cis-isoprene units. The alpha-terminal group of Jackfruit rubber was presumed to be composed of a phosphate group based on the presence of 1H NMR signal at 4.08 ppm corresponding to the terminal =CH-CH2OP group.

Because of the increased demand and depletion of fossil hydrocarbons, the researchers have now started to pay attention toward exploitation of new energy plants and biomass of plants as alternate source of fuels and petrochemicals. Mangroves which possess enormous economic potential and utilitarian value in the ecosystem are very promising as energy plants, because they are fast growing and most of them contain abundant fatty acids, hydrocarbons, and so forth. In this article, the isolation of a white waxy amorphous solid from the hexane extract of leaves of Finlaysonia obovata is described, a mangrove plant which was found to be a mixture of saturated straight-chain, branched-chain, and long-chain linear aliphatic hydrocarbons by gas chromatography-mass spectrometry analysis. The waxy solid showed the existence of hydrocarbons ranging from 8 to 30 carbon atoms. The waxy solid contains more than 70% of linear saturated long-chain hydrocarbons. Among the saturated hydrocarbons, the content of docosane and pentacosane were found to be the major ones. The other major saturated hydrocarbons are tetradecane, hexadecane, and triacontane. Its high carbon content (85-90%) and absence of nitrogen and oxygen indicates its good fuel quality. The similarity of physical/ spectral characteristics of the waxy component with other renewable sources of hydrocarbons from the literature is discussed, and the results obtained are very promising.
