Genetic engineering of peppermint for improved essential Oil Composition and yield
Transgenic Research, 2005Co-Authors: Mark R. Wildung, Rodney B. CroteauAbstract:The biochemistry, organization, and regulation of essential Oil metabolism in the epidermal Oil glands of peppermint have been defined, and most of the genes encoding enzymes of the eight-step pathway to the principal monoterpene component (−)-menthol have been isolated. Using these tools for pathway engineering, two genes and two expression strategies have been employed to create transgenic peppermint plants with improved Oil Composition and yield. These experiments, along with related studies on other pathway genes, have led to a systematic, stepwise approach for the creation of a ‘super’ peppermint.

Grapefruit gland Oil Composition is affected by wax application, storage temperature, and storage time.
Journal of Agricultural and Food Chemistry, 1999Co-Authors: Peter D. PetracekAbstract:: The effect of wax application, storage temperature (4 or 21 degrees C), and storage time (14 or 28 days after wax application) on grapefruit gland Oil Composition was examined by capillary gas chromatography. Wax application decreases nonanal and nootkatone levels. beta-Pinene, alpha-phellandrene, 3-carene, ocimene, octanol, trans-linalool oxide, and cis-p-mentha-2,8-dien-1-ol levels increase, but limonene levels decrease, with temperature. Levels of alpha-pinene, limonene, linalool, citronellal, alpha-terpineol, neral, dodecanal, and alpha-humulene decrease with time. Levels of alpha-phellandrene, 3-carene, ocimene, and trans-linalool oxide increase with time. No compound level was affected by the interactive action of temperature and wax application, suggesting that these two factors cause grapefruit Oil gland collapse (postharvest pitting) through means other than changing gland Oil Composition. Compounds that are toxic to the Caribbean fruit fly (alpha-pinene, limonene, alpha-terpineol, and some aldehydes) decrease with time, thus suggesting grapefruit becomes increasingly susceptible to the fly during storage.

Distillation waste water can modify peppermint (Mentha ×piperita L.) Oil Composition
Industrial Crops and Products, 2012Co-Authors: Valtcho D. Zheljazkov, Tess AstatkieAbstract:We evaluated the effects of foliar sprays made of residual distillation waters from 13 species containing essential Oil (Melissa officinalis, Mentha arvensis, M. gracilis, M. ×piperita, M. spicata, Monarda citriodora, Nepeta mussinii, Porophyllum ruderale, Rosmarinus officinalis, Salvia officinalis, Satureja montana, Tagetes lucida, and Thymus vulgaris), hot water extracts from two alkaloid-containing species (Glaucium flavum, Datura innoxia), and three plant hormones (methyl jasmonate, gibberellic acid, and salicylic acid) on growth, productivity, and essential Oil content and Composition (α-pinene, β-pinene, sabinene, myrcene, l-limonene, 1,8-cineole, l-menthone, menthofuran, d-isomenthone, menthyl acetate, neo-menthol, b-caryophyllene, l-menthol, pulegone, germacrene-d, and piperitone) of peppermint (Mentha ×piperita L.) ‘Black Mitcham’. The results showed significant effects of the treatments on plant height and weight, essential Oil content and yield, and essential Oil Composition. Cluster analysis indicated similarities between the effects of plant hormones and some extracts on peppermint Oil Composition. None of the distillation waters had strong in vitro antimicrobial activity. The results indicated that residual distillation water of some plant species may influence monoterpene synthesis and accumulation in peppermint and hence may be used for targeted modification of peppermint essential Oil Composition.

Cultivar and sowing date effects on seed yield and Oil Composition of coriander in Atlantic Canada
Industrial Crops and Products, 2008Co-Authors: Valtcho D. Zheljazkov, Kelly M. Pickett, Claude D. Caldwell, J. A. Pincock, Jeffrey C. Roberts, Lloyd MapplebeckAbstract:Abstract The hypothesis of this study was that coriander grown in the cool wet conditions of Atlantic Canada would have comparable Oil Composition to coriander Oil marketed internationally and would have a potential as a cash crop for the region. Field experiments were conducted in 2001 and 2002 to evaluate the effect of seeding date (24 May and 8 June) and location (Truro and Canning, Nova Scotia) on yield and essential Oil quality of coriander cultivars ‘Jantar’ and ‘Alekseevski’. Plants grew well and had normal to high seed essential Oil content. However, seed and essential Oil yields were low, suggesting that the crop would not compete well for a place in Atlantic Canada agriculture. In both years, the earlier seeding date (24 May) enhanced productivity. The two cultivars had dissimilar Oil content, Oil and seed yields. The Oil Composition of tested cultivars was similar to coriander Oils from India and Hungary with linalool as the main component. Hence, essential Oil produced in Atlantic Canada should be easily marketed as are the essential Oils produced in India and Hungary. Coriander seeds produced in Atlantic Canada contained normal to high amount of linalool (64–84.6%). The other Oil constituents were camphor (3.4–6.2%), α-pinene (1.2–3.2%), phellandrene (1.7–4.1%), linalyl acetate (2.4–3.3%), limonene (0.7–1.8%), para -cymene (0.5–1.3%), and geranyl acetate (0.9–1.6). Both cultivar and seeding date affected Oil Composition. Further research on fall and early spring seeding dates and on the crop mineral nutrition is needed in the region to increase seed yields and essential Oil productivity.

Review of the Essential Oil Composition of Iranian Endemic and Native Taxa of Apiaceae (Umbelliferae)
Current Organic Chemistry, 2020Co-Authors: Maryam Akaberi, Javad Asili, Zahra Tayarani-najaran, Iraj Mehregan, Amirhossein Sahebkar, Mohammad Hassanzadeh-khayyat, Seyed Ahmad EmamiAbstract:One of the most important families of Iranian flora is Apiaceae (Umbelliferae). Most of the species of this family are aromatic plants and rich in essential Oils with diverse structures. In the present review, the essential Oil Composition of 63 genera comprising 141 Apiaceae (66.4% native 33.6% endemic) is summarized.
