Antifungal and larvicidal activities of two acyclic monoterpenes; citral and geraniol against phytopathogenic fungi and insects

Archives of Phytopathology and Plant Protection, 2019
Citral and geraniol are dominating constituents of lemon and rose scented essential oils of Cymbopogon spp. Here, we report their antifungal activity against some pathogenic fungi Drechslera oryzae, Fusarium oxysporum, Rhizoctonia solani and Sclerotium ...

Microbial hydroxylation of activated acyclic monoterpene hydrocarbons

Tetrahedron, 1992
Abstract While fermentation of myrcene and ocimene led to products in very low yields, good yields were obtained by protection and activation of the diene moiety by sulfur dioxide. Microbial hydroxylations of the sulfolenes 1 and 14 yielded 8-hydroxycompounds in up to 60% yield. Bacteria favour the 8Z- while fungi produce mainly the 8E-alcohol.

An Acyclic Monoterpene Glucosyl Ester fromLantana lilacia

Planta Medica, 1998
A new acyclic monoterpene glucosyl ester was isolated from the leaves of Lantana lilacia together with the known compound, acteoside. The structure of the new compound was elucidated by spectroscopic and chemical analyses.

ω-Hydroxylation of acyclic monoterpene alcohols by rat lung microsomes

Biochemical and Biophysical Research Communications, 1982
Rat lung microsomes were shown to ω-hydroxylate acyclic monoterpene alcohols in the presence of NADPH and O2. NADH could neither support hydroxylation efficiently nor did it show synergistic effect. The hydroxylase activity was greater in microsomes prepared from β-naphthoflavone (BNF)-treated rats than from phenobarbital (PB)-treated or control ...

Role of acyclic compounds in monoterpene biosynthesis in Pinus pinaster

Phytochemistry, 1982
Abstract The biosynthesis of monoterpene hydrocarbons was studied in maritime pine needles by incorporation of 14CO2. It was shown that the acyclic terpenes β-myrcene and trans-β-ocimene, act as transitory compounds before the biosynthesis of cyclic monoterpenes such as α- and β-pinene. The mechanisms of biosynthesis are genetically controlled.

Thienyl analogues of acyclic monoterpene alcohols and their biological activity

Journal of the Science of Food and Agriculture, 2009
AbstractBACKGROUND: Thienyl analogues of linalool, geraniol, nerol and citronellol were synthesised and their sensory and anti‐ microbial activities were investigated.RESULTS: The thienyl analogues of linalool, geraniol, nerol and citronellol, in which the isobutenyl moiety was replaced by a thiophene substituent, were synthesised from commercially ...
