Identification and quantification of selected metabolites ... In this paper, we analyzed the chemical composition of the essential oil from Datura Stramonium L. and determined their phytotoxic activity on five cultivated crops. Differently colored lettuce (Lactuca sativa L.) cultivars (green, green/red, and red) were studied to correlate their phenolic composition with their antioxidant kinetic behavior. An average weight of lettuce head was in the range of 147.65-296.82 g. N2 - Eight varieties of lettuce (Lactuca sativum) and three varieties of endive (Cichorium endivia) were analyzed for flavonoid composition and content. The species studied were: Davilla elliptica, Combretum laxumHimatanthus obovatus, , Diteryx alataCuratella , americana, Qualea grandiflora, Aspidosperma macrocarpon, Caryocar brasiliensePleroma candolleanum , and Miconia Chemical composition of vegetables grown on an ... 1.2 General Objective This study therefore seeks to assess the nutritional and chemical composition of water lettuce, to determine it suitability for use as livestock feed. Methods: Chemical composition of extracts was determined by using GC-MS equipment. pH, EC, total N, total P and total K, organic matter organic carbon, C/N ratio and E. coli in the original substrates (e.g., molasses, distillery slop and sugarcane leaves) were measured and the results of chemical properties of the original substrates are shown in Table 1.The average EC values of molasses and distillery slop were 39.10 and 32.86 dS/m .

Contact tests showed that the germination of lettuce seeds was totally inhibited by all the essential oils except of the samara oil at a dose of 1 mg/ml. Volume 33, Issue 1, February 2014, Pages 39-48. crispa, is one of many leaves that fall under the Asteraceae family. is necessary to check its chemical composition with par-ticular regard to toxic elements such as arsenic. To date, studies on the lettuce composition of phenolic compounds and its potential as antioxidant were focused on baby-leaf and mature stages of lettuce [1, 8, 18, 19]. successfully used a modified Sonneveld's recipe for growing lettuce Table 1. The application of iodine compounds had a significant influence on increasing the lettuce head weight, dry matter content, and chemical composition in lettuce leaves . Background The uptake of arsenic by vegetables from soil irrigated with arsenic enriched groundwater poses a major health hazard. chemical composition: All types of lettuce, including Wild Lettuce, contain white milky juice in the leaves and stems, in which bitter substances (lactucerin, lactucin, lacticitin), alkaloids, tarry and other substances are found. Essential nutrients and Cd accumulation in plant tissue depends on the lettuce varieties. 2.1 General properties. Abstract. Cabbage is a mixture of many substances, cabbage doesn't have a well defined composition as a lot depends on the time of the year, time of a day, place where it is grown and so on. title = "Allelopathic potential and chemical composition of rhinacanthus nasutus extracts", abstract = "Aqueous methanol extracts of Rhinacanthus nasutus (L.)

Two-factor experiment was carried out in a completely randomized system. These give your taste buds a mouth-watering experience in every bite. JA-elicitation slightly affected the yield of plants and significantly increased the amount of essential oils produced by basil - the highest oil yield (0.78±0.005mL/100gdw) was achieved in . Temperature, both in terms of total or average temperature and the extremes during the growth period, may influence the chemical composition in plants [18, 19]. Fruit and vegetables have many similarities with respect to their compositions, methods of cultivation and harvesting, storage properties and processing. A two-year greenhouse study was conducted to assess the effects of the application of I (as KIO3), Se (as Na2SeO3), and salicylic acid (SA) in nutrient solutions on the chemical composition of six lettuce cultivars, i.e., two butterhead lettuces Not only would the chemical characteristics of the mineral soil or soilless media used in the "soil" grown lettuce affect the nutrient composition, but the physical characteristics (e.g. Omega F1 grown in greenhouse, the effect of three nitrogen doses (0.25; 0.50; 0.75 g dm-3) and different types of potassium fertilizer (K2SO4, KCl, KNO3) on the yield and chemical composition of leaves was investigated. Chemical composition and crystal structure are the most important factors in determining the properties of a mineral, including shape, density, hardness, and color.Geologists use these properties to identify which minerals are present in rocks.

Lactuca virosa is a plant in the Lactuca (lettuce) genus, often ingested for its mild analgesic and sedative effects. Arsenic contamination of the groundwater and soil is a major en-vironmental toxicity issue, especially in South-east Asia and in countries like China, Hungary, Iceland, Mexico, Chile, Argentina, Brazil, and USA (Santra et al. The results obtained in this study indicate that SA application (at three different doses), when combined with I + Se, has no adverse influence on lettuce growth and development and, consequently, on leaf and root biomass.

Lactucarium is the milky fluid secreted by several species of lettuce, especially Lactuca virosa, usually from the base of the stems.It is known as lettuce opium because of its putative sedative and analgesic properties. Monoterpene hydrocarbons—which are responsible for the oil's aroma—mostly account for the largest contribution to the EO content (> 60%), with α-pinene Figure 1 (1), being the major or second-leading component detected in . The essential oil was extracted from the plant rhizome by hydrodistillation and subjected to gas chromatography- mass spectrometry to identify its component chemical compounds. Nevertheless, this type of data is not yet widely presented in food composition tables and databases disaggregating biodiversity, nutrition and agriculture.
