“…Also, during three years of cultivation of hyssop in Finland, the content of pinocamphone varied between 18.0 and 19.7%, isopinocamphone between 29.2 and 32.6%, germacrene D between 6.7 and 10.2%, β-pinene between 5.2 and 6.6% and pinocarvone between 5.3 and 5.7% [41]. In addition, investigations conducted in Ukraine for three years showed significant variations in the content of pinocamphone (from 35.49 to 53.73%) and isopinocamphone (4.66 to 44.43)% depending on plant age [42].…”

This paper is a study of the chemical composition of Hyssopus officinalis ssp. officinalis grown during three years (2017–2019) at the Institute of Field and Vegetable Crops Novi Sad (Vojvodina Province, Serbia). Furthermore, comparisons with ISO standards during the years were also investigated, as well as a prediction model of retention indices of compounds from the essential oils. An essential oil obtained by hydrodistillation and analysed by GC-FID and GC-MS was isopinocamphone chemotype. The gathered information about the volatile compounds from H. officinalis was used to classify the samples using the unrooted cluster tree. The correlation analysis was applied to investigate the similarity of different samples, according to GC-MS data. The quantitative structure–retention relationship (QSRR) was also employed to predict the retention indices of the identified compounds. A total of 74 experimentally obtained retention indices were used to build a prediction model. The coefficient of determination for the training cycle was 0.910, indicating that this model could be used for the prediction of retention indices for H. officinalis essential oil compounds.

Bu araştırmada, farklı azot dozlarının (0, 4, 8, 12 ve 16 kg da-1) Origanum syriacum var. bevanii ‘nin verim ve verim öğeleri üzerine etkisinin belirlenmesi amaçlanmıştır. Çalışma tesadüf blokları deneme desenine göre 3 tekerrürlü olarak Eskişehir ekolojik koşullarında 2019-2020 yıllarında yürütülmüştür. Çalışmada bitki boyu, taze herba verimi, kuru herba verimi, kuru yaprak verimi, uçucu yağ oranı ve uçucu yağ verimi incelenmiş, farklı azot dozlarının uçucu yağ oranı hariç incelenen parametrelerin üzerine etkisi önemli bulunmuştur. Çalışmada iki yılın ortalaması olarak verimler (2019 ve 2020 yılları ortalaması) taze herbada 787.65-1267.50 kg da-1, kuru herbada 440.10-708.22 kg da-1, kuru yaprakta 235.92-379.62 kg da-1 ve uçucu yağda 8.33-12.53 L da-1 arasında değişmiştir. Uçucu yağ oranları ise %3.23-3.47 arasında belirlenmiştir. Çalışılan parametrelerde (uçucu yağ oranı hariç) en yüksek değerler 16 kg da-1 azot dozundan elde edilmiştir.

Hyssopus officinalis L. is a promising essential oil plant of complex use containing various types of biologically active substances (BAS). The purpose of the research was twofold: study the features of accumulation of various types of BAS in H. officinalis plants grown in the foothill zone of the Crimea; assess the possibility to use them in perfumery, cosmetics, food industry, pharmacy and medicine. The research was conducted in 2017–2019 in the FSBSI “Research Institute of Agriculture of Crimea”. The raw materials of H. officinalis (population with blue flowers) grown without irrigation served as the research material. Qualitative and quantitative characteristics of raw materials and different types of BAS were determined according to generally accepted methods. Structural analysis of H. officinalis showed that the aboveground part of plants during the growing season had the following fractional composition: leaves (21.4–70.6 %), stems (18.8–30.9 %), inflorescences (22.0−59.1 %). The ratio of fractions by phases of vegetation varied, namely: in the phase of regrowth, leaves prevailed – 70.6 % but, at the end of the flowering, their content decreased to 21.4 %; the content of inflorescences reached its maximum in the phases of mass flowering and end of flowering 53.3–59.1 %. The main oil-synthesizing organs of H. officinalis were leaves and inflorescences. The highest yield amount of H. officinalis essential oil was obtained from inflorescences (1.94 %), which in the fractional composition of the raw material amounted to 53.3 %. The maximum amount of essential oil of specific quality accumulated in plants during the phase of mass flowering (1.26 % in terms of absolutely dry weight). The dominant components of essential oil are ketones: isopinocamphone and pinocamphone (75.9–78.6 %). A high level of phenolic compounds was determined in the phases of regrowth and flowering; extractive substances – in the budding phase; tannins – in the phase of mass flowering. During the storage of air-dry raw materials for two years, insignificant losses of essential oil occur (up to 20.2 %); its component composition changes (hydrocarbons amount decreased by 2.5–22.7 %; ketones – increased by 3.4–16.2 %). The content of other types of BAS during storage of raw materials increased by 10–30 %. Therefore, it is advisable to store air-dry raw materials of Hyssopus officinalis for two years or longer.
