“…A derivative of phytol, 3,7,11,15-tetramethyl-2-hexadecene (15.5 -15.93 min retention time) was also detected in all samples but at lower concentrations. Phytol is commercially used as a precursor for the manufacture of synthetic forms of vitamin E [58] and vitamin K1 [59] Phytol is also used in the fragrance industry and used in cosmetics, shampoos, toilet soaps, household cleaners and detergents [60]. Its worldwide use has been estimated to be approximately 0.1 -1.0 metric tons per year [www.ifraorg.org/view_document.aspx?docId=22594].…”

Aquatic plants aggressively colonising wetlands are widely used for the biosorption of the soluble contaminants from wastewater and represent an attractive feedstock for biofuel production. Three common Australian aquatic plants, duckweed (Landoltia punctata), elodea, (Elodea canadensis) and water clover (Marsilea quadrifolia), colonizing different depths of wetlands were tested for their ability to treat the selenium-rich mining wastewater and for their potential for production of petrochemicals. The results showed that these plants could be effective at biofiltration of selenium and heavy metals from mining wastewater accumulating them in their fast growing biomass. Along with production of bio-gas and bio-solid components, pyrolysis of these plants produced a range of liquid petrochemicals including straight-chain C14-C20 alkanes, which can be directly used as a diesel fuel supplement or as a glycerine-free component of biodiesel. Other identified bio-oil components can be converted into petrochemicals using existing techniques such as catalytic hydrodeoxygenation. A dual application of aquatic plants for wastewater treatment and production of value-added chemicals offers an ecologically friendly and cost-effective solution for water pollution problems and renewable energy production.

“…Phytol, contained in the extract of Anredera cordifolia leaf, is a precursor of vitamin E and vitamin K, which are important for body hemostatic in the first phase of wound healing and to promote this phase. Phytol also has a role in wound contraction and promotes epithelialization [10,11]. In this research, macroscopic analysis of wound healing found shorter and faster inflammatory phase in the treatment group.…”

“…25 Thus the abundant presence of phytol in leaves of Allophylus species suggests that these species may prove helpful in prevention of degeneartive diseases. As well as, phytol is used in artificial synthesis of vitamin E and vitamin K 26,27 Additionally, phytol has various applications in cosmetics and fragrance industry 28 suggests the application of these herbs in cosmetics, which may prove a cost effective alternative to current synthetic chemicals used in current cosmetic industry. Thus, the further detailed studies of each compound will ascertain phytopharmaceutical activity of A. cobbe and A. serratus.…”

Background: Allophylus cobbe(L.) Raeusch. and Allophylus serratus (Roxb.)Kurz. (Sapindaceae) are medicinal plants traditionally used to cure bone fractures and other ailments in India. Objective: Present work was aimed at the identification of phytochemical compounds from young leaves of A. cobbe and A. serratus by applying gas chromatography mass spectrometry. Method: GC-MS technique was used for analysis of compounds. Results: It indicates 11 compounds from A. serratus and seven compounds from A. cobbe having mixture of terpenoids, alkanes and fatty acids. The major compounds found in A. cobbe were 1,1-diethoxy ethane (82.97%) (RT: 3.192min), phytol (7.07%) (RT: 43.690 min) and hexanoic acid (3.67%) (RT: 29.576 min) while in A. serratus 3-methyl butanol (53.16%) (RT: 3.223 min), 2-propenoic acid, 2-(dimethylamino) ethyl ester (27.08%) (RT: 13.94 min) and diisocytyl phthalate (4.49%) (RT: 52.584 min) were found in higher quantity. Phytol was detected from both species. Phytol possesses anti-radical, anti-cancer, antibacterial and anti-inflammatory properties as well as used in artificial synthesis of vitamin E and vitamin K in cosmetics and fragrance industry. Conclusion:The abundant presence of phytol in leaves of Allophylus species (7.07% in A. cobbe and 2.60% in A. serratus) suggests that these species may prove helpful in prevention of degenerative diseases and application of these herbs in cosmetics which may prove a cost effective natural alternative to current synthetic cosmetics. Presence of industrially important chemicals like phytol, 1,1-diethoxy ethane, hexanoic acid, diisocytyl phthalate, 2-propeonic acid, 2-(dimethylamino) ethyl ester underlines industrial importance of these species which needs further research on this aspect to focus in detail.
