Gonceariuc Maria, Balmuş Zinaida, Benea Ana, Barsan Victoria, Sandu Tatiana. // Journal of Academy of Sciences of Moldova. Life sciences. 2015, No 3(326), p. 92-100. Five genotypes of O.vulgare ssp. vulgare L. and five genotypes of O.vulgare ssp. hirtum have been assessed. The diversity of O. vulgare ssp. vulgare. and O. vulgare ssp. hirtum genotypes has been confirmed through the essential oil content, qualitative and quantitative components. The content of the essential oil separated by hydrodistillation varies between 0,077% and 0,360% in the genotypes O.vulgare ssp. vulgare, and between 2,315% and 4,923% in the O.vulgare ssp. hirtum genotypes. Qualitative and quantitative analyses performed using GC GC-MS techniques have found from 18 to 29 components in the O.vulgare ssp. vulgaris essential oil, depending on the genotype, the identification ratio being 92,38%-98,80%. The component number varies between 18 and 25 depending on the genotypes of O. vulgare ssp. hirtum, this constituting 99,87-100 % of the essential oil. The major components in the essential oil of O. vulgare ssp. vulgare include Germacrene D (33,98–26,01%); β-Caryophyllene (12,16–33,16%); γ-Elemene (3,82 – 16,79%), while β- Bisabolene (6,83-16,04) is the major component in four genotypes. The O. vulgare ssp. vulgare genotypes are divided into five chemotypes: 1. Germacrene D/β-Caryophyllene/β-Bisabolene; 2. Germacrene D/β-Caryophyllene/δ-( )Cadinole/ γ-Elemene; 3. Germacrene D/ γ-Elemene/ β-Caryophyllene/ β- Bisabolene; 4. β-Caryophyllene/ Germacrene D/ β- Bisabolene; 5. Germacrene D/ β-Caryophyllene/γ-Elemene/β- Bisabolene. The major components in the essential oil of O. vulgare ssp. hirtum are carvacrol (77,61-85,88%), followed by p-cymene (3,64-9,33%) or γ-terpinene (8,22%) and p-cymene (5,30%). The O.vulgare ssp. hirtum genotypes are divided into two chemotypes: 1-carvacrol/γ-terpinene/p-cymene and carvacrol/γ-terpinene/p-cymene/ β-Caryophyllene. The variability of the content of polyphenols in the genotypes of both subspecies has been demonstrated. Rich in polyphenols are genotypes belonging O.vulgare ssp. vulgaris: from 99,25 ± 1,598 to 166,43±3,594 mg/100g. The genotypes of O.vulgare ssp. hirtum, synthesizes and accumulate polyphenols from 53,51± 0,684 to 85,59±0,719 mg/100g. 42references, 3 tables. |
