The chemical composition and activity of herbal raw material depend, among others, on ontogenetic variability. The present study investigated the effect of harvest date of winter savory (Satureja montana L.) herb and plant age on fresh and dry herb yield as well as on the content of L-ascorbic acid, carotenoids, chlorophylls, essential oil, flavonoids and tannins. S. montana herb from a one- and two-year-old...
Similarly to other species of the genus Satureja (Lamiaceae), winter savory is valued in traditional medicine in many countries of the world. Most studies on winter savory are primarily focused on the chemical composition and biological activity of its raw material, but few studies concern proper growing conditions. The aim of the present study, conducted on one-year-old plants, was to determine relationships...
Winter savory (Satureja montana L.) is an aromatic subshrub of significant medicinal and seasoning qualities. Winter savory herb yield and quality depend on various factors, including environmental and agronomic ones. The aim of the present study was to evaluate the effect of winter savory plantation establishment method (seedlings, herbaceous cuttings) on the morphological traits and raw material...
Artichoke is valued as a vegetable and medicinal plant. The aim of the study was to determine the effect of irrigation and leaf harvest date of artichoke grown in southeastern Poland on total yield and marketable fresh leaf yield, its structure and the content of biologically active substances: total phenolic acids, flavonoids and tannins. Irrigation contributed to an increase in fresh leaf yield,...
Biochemical assessment was performed of leaves, flower buds and flowers of lavender. High positive correlation was demonstrated between the essential oil contents and antioxidant activity (AA) (R = 0.9688), total phenolic acids and AA (R = 0.9303), as well as high negative correlation between flavonoid contents and AA (R = -0.9760). Results of the foregoing studies also suggest that AA of lavender...
Horehound herb (Marrubium vulgare L.) is harvested from plantations in Poland. In our country, there are also favorable conditions for M. incanum Desr. growing. The aim of the study was to compare the chemical composition of essential oils from M. vulgare L. and M. incanum Desr. in the second year of cultivation. The study revealed the presence of 31 compounds in the essential oil from M. vulgare...
Lemon balm, garden sage and common thyme are herbal species possessing versatile medicinal properties. They are also used as spices for culinary purposes. In the Polish climate, despite being perennial, these herbs usually grow on plantations for a year. The reason is their tendency to develop more lignified lower parts of stems, which in consequence depreciates the quality of yield and make the plants...
The quality of fresh herbs used mainly as food products, is dependent on a number of factors, including the agronomic and environmental ones. The pharmacopoeial material of summer savory is the whole or ground herb, which besides essential oil, contains many other biologically active compounds, such as tannins, carotenoids, flavonoids, and minerals. The aim of the study was to evaluate the yielding...
A two years’ field study was conducted to compare the influence of perennial ryegrass (Lolium perenne L.), white clover (Trifolium repens L.), perennial ryegrass + white clover mixture and mowed weeds used as living mulches with the influence of linuron 675 g·ha-1 on weed infestation and yield of carrot (Daucus carota L.) ‘Flakkese 2’ under ridge cultivation. Living mulches did not affect growth of...
