Summary
Key words: plant pigments, optical density of chlorophyll, concentration of pigment, plant extract, light wavelength, light quantum, alcoholic solution of chlorophyll
The study of chlorophyll and carotenoid concentrations in the stems and leaves of ten plant species collected from the wild flora of the Vanadzor region of Lori marz, revealed that the concentrations of chlorophyll a and chlorophyll b was different in the vegetative organs of these plants. In the five of the investigated plant species growing in Vanadzor Thymus serpyllum L., Chaerophyllum bulbosum L., Chelidonium majus L., Heracleum sosnowskyi, Polygonatum odoratum (Mill) Druce – chlorophyll a concentration was higher in the stem. Meanwhile, in the five other species – Teucrium polium L., Asparagus officinalis L., Mentha viridis L., Apium graveolens L., Urtica dioica L., chlorophyll a concentration was higher in the leaves. Regarding chlorophyll b, the concentration was higher in the stems of seven plant species Thymus serpyllum L., Asparagus officinalis L., Mentha viridis L., Chaerophyllum bulbosum L., Chelidonium majus L., Heracleum sosnowskyi, Polygonatum odoratum (Mill) Druce. While in the three species Apium graveolens L., Urtica dioica L., Teucrium polium L. it was higher in the leaves. Based on carotenoid concentration data, we recommend that the residents of Vanadzor incorporate the stems of Teucrium polium L., Asparagus officinalis L., Mentha viridis L., Apium graveolens L., Urtica dioica L., Heracleum sosnowskyi. into their diet and daily use.
