Antioxidant Activity of Basil
نویسنده
چکیده
INTRODUCTION The commercial development of plants as sources of antioxidants to enhance health and food preservation is of current interest (Rice-Evans et al. 1997). Epidemiological studies have suggested positive associations between the consumption of phenolic-rich foods or beverages and the prevention of diseases (Scalbert and Williamson 2000). These effects have been attributed to antioxidant components such as plant phenolics, including flavonoids and phenylpropanoids among others (Rice-Evans et al. 1996). Basils (Ocimum spp., Lamiaceae) contain a wide range of essential oils rich in phenolic compounds (Simon et al. 1990; Phippen and Simon 2000) and a wide array of other natural products including polyphenols such as flavonoids and anthocyanins (Phippen and Simon 1998). The objective of this study was to evaluate the antioxidant activity of basil extracts and essential oils.

Effects of Exogenous Nitric Oxide on Germination and Physiological Properties of Basil under Salinity Stress
Nitric oxide (NO) is a bioactive molecule, which was found to have several physiological roles, including antioxidant. To have a better understanding of the effects of NO concentrations (0, 0.1 and 0.2 mM) on germination, growth, photosynthetic pigments, lipid peroxidation and antioxidant activity of basil (Ocimum basilicum L.) under different salinity concentrations (0, 100 and 200 mM of NaCl)...
متن کاملChanges in antioxidant enzymes activity and physiological traits by exogenous salicylic acid in basil (Ocimum basilicum) under Pb stress
Salicylic acid (SA) is a key molecule that alleviates abiotic stress in many plant species. In this study, the role of SA was examined to moderate lead (Pb) toxicity in the basil (Ocimum basilicum). The experimental design was a randomized complete block design with 4 levels of PbNO3; 0 (control), 100, 200 and 300 mg kg-1 of soil as the first factor, and the foliar application of SA at 3 levels...

Many herbs and spices have been shown to contain high levels of polyphenolic compounds with potent antioxidant properties. In the present study, we explore how nutrient availability, specifically nitrogen fertilization, affects the production of polyphenolic compounds in three cultivars (Dark Opal, Genovese, and Sweet Thai) of the culinary herb, basil ( Ocimum basilicum L.). Nitrogen fertilizat...

Basil is an important medicinal plant, belonging to the Lamiaceae family. Basil is used for the treatment of different diseases such as stomachache, headache, constipation, fever and infections, as well as to reduce and regulate the blood sugar. Moreover, Basil is known for its antibacterial, antifungal and antioxidant properties. In this study, the impact of drought stress on phenols and flavo...
متن کاملBenefits of Silicon Nutrition on Growth, Physiological and Phytochemical Attributes of Basil upon Salinity Stress
In the present study, improvement of salt tolerance in basil (as a salt-sensitive plant) was investigated through silicon (Si) nutrition. Basil plants were subjected to silicon (0, 3 mM) and salinity (0, 50, 100, 150 and 200 mM NaCl) for a duration of one month. Salt stress significantly decreased the biomass of basil. Si supplement (3 mM) resulted in a considerable increase (averagely +135%) i...
