A field experiment was conducted from 1989 to 1991 on a Fox loamy sand soil to study the effects of harvest date on selected agronomic, physical and chemical characteristics of peppermint (Mentha piperita L.). Plant biomass and essential oil yields increased throughout the season to a maximum in very late August to early September. Menthol, neomenthol, and menthyl acetate concentrations increased in the essential oil with plant development. The amount of menthone and isomenthone was highest in immature plants. The concentrations of menthofuran and pulegone in the essential oil corresponded to the amount of flower bloom in the peppermint. Changes during the season in the concentrations of piperitone, terpinene-4-ol, α-terpineol, 1,8-cineole, limonene, γ-terpinene, terpinolene, α-terpinene, α-pinene, β-pinene, 3-octanol, β-myrcene, Linalool, sabinene, caryophyllene and Germacrene-D were typically quite small. In general, these preliminary results indicate that peppermint can be grown successfully on the coarse-textured soils of Ontario.

Physical And Chemical

Perilla frutescens essential oil was studied in this work for its physico-chemical characteristics and composition. The essential oil was obtained yields by 0.1%. The physico-chemical properties of the oil were also discovered including the physico-chemical parameters averaged 0.944 g/cm3 for specific gravity, acid index (9.185 mg KOH/g), ester index (28.66 mg KOH/g), refractive index (1.4976). Thought gas chromatography/mass spectrometry (GC/MS). The results revealed that the oil is extremely rich in myristicin (43.896%), elemicin (28.793%), α-caryophyllene (8.327%), perillaldehyde (7.973%), (Z,E)-farnesene (2.807%), D-limonene (1.043%). The results showed that the morphological characteristics and the polymorphism in the essential oil composition of perilla leaves were reliant on the harvesting time and geographical cultivate. Perilla essential oil is antioxidant, antibacterial and used in many studies, helping to find its effect on Alzheimer′s disease, memory loss, concentration and anti-depressive concentration, because it contains unique compounds as above

The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based on the fresh weight. The oil was analysed by capillary GC and GC- MS. Thirty seven constituents, representing 97.81 % of the oil were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lavandulyl acetate (4.34 %) and ?-terpineol (3.75 %). The quality of lavender oil produced in India was found to be comparable to that produced in Hungary, France, China, Bulgaria, Russia and the USA.

The developed complex scientific-methodical approach to the survey of organic agricultural enterprise was presented in order to confirm the quality of aromatic products of the “Organic” class. The analysis of agrochemical soils indicators was performed for the first time, which were cultivated according to organic technology for eleven years. It was proven that long-term use of organic farming contributes to the preservation and improvement of soil fertility. An elemental biomass analysis of the apical part of lavender plants grown by organic method was carried out, from which the essential oil was then obtained. It was confirmed that the essential oil composition depends on the place of its production and on the soil characteristics on which the plants were grown. The elemental analysis of essential oil showed that there is an intensive carry-over of all major macro- and micronutrients from the soil into plants during their growth and development. In the lavender essential oil, there are more than 50 substances that determine its uniqueness. Therefore, to confirm the quality of “Organic” class products, we propose to conduct a comprehensive assessment of all components of the organic production system “soil — plant — products”. Thermal analysis, electron microscopy with detectors for energy dispersion analysis, chromatographic analysis, potentiometry, flame photometry and chemical analytical methods were used for the research. Differences in quality indicators of organic essential oil and oil obtained with the traditional farming method were revealed. The study found that the produced lavender oil is a unique quality product grown in an organic way. At present, quality management of agricultural products is possible subject to specialists' availability in the agro-industrial complex with competence in the field of chemical-toxicological and environmental analysis knowing methods to determine the quality and safety of agricultural products, including organic products.
