Multiple field studies have suggested chemistry within a forest canopy is poorly understood due to inadequate detection and quantification of reactive biogenic emissions, such as terpenes. To measure emission rates of terpenes at Blodgett Forest, a coniferous forest in the Sierra Nevada mountains of California, we placed enclosures over branches of the dominant species at the site – Ponderosa p...

The chemical compositions of essential oils obtained from Ocimum basilicum var. thyrsiflora (1.39 % dry weight) and Ocimum basilicum (0.61 %) were analyzed by GC–MS. Seventy-three constituents representing 99.64 % of the chromatographic peak area were obtained in the O. basilicum var. thyrsiflora oil, whereas 80 constituents representing 91.11 % observed in the essential oil of O. basilicum wer...

recent data showed that phenylpropanoid compound, methylchavicol is essential component of iranian cultivars of basil. studying their occurrence during development of plant may help to elucidate the role of phenylpropanoids in plant cell physiology. we followed the phenylpropanoids concentration and the expression of genes related to their biosynthesis during growth and development of two culti...

There are distinct varieties of basil types in the genus Ocimum L. which makes them very special. Genus Ocimum L. is widespread over Asia, Africa, Central and Southern America. All basils are member of the Lamiaceae family. The colors of the leaves vary from bright green to purple-green and sometimes almost black. Fresh basil leaves have a strong and characteristic aroma, plant which is used in...

A complete study was conducted through manufacturing of Microencapsulation Basil Oil Powder (MEBOP) and Thyme (METOP) to evaluate the anti-bacterial activity against aquatic pathogens. An oil-in-water emulsion were prepared using gum with dextrin resultant matrix spray dried average yield 45% w/w MEBOP 50% METOP. Total oil content in encapsulated powder both found be 24.39% 25.80% METOP respect...

The study was conducted to determine fennel essential oil (FEO) yield, composition, and antioxidant activity during four different maturation stages of umbels with seeds (1st stage: immature-pasty; 2nd premature-waxy; 3rd mature-fully ripe; 4th only), leaves wild (Foeniculum vulgare Mill. subsp. vulgare) from the Montenegro coast. maximum yield found in premature at waxy stage (4.76 mL/100 g p....

4-ethylphenol methylenehydroxylase from Pseudomonas putida JD1 acts by dehydrogenation of its substrate to give a quinone methide, which is then hydrated to an alcohol. It was shown to be active with a range of 4-alkylphenols as substrates. 4-n-propylphenol, 4-n-butylphenol, chavicol, and 4-hydroxydiphenylmethane were hydroxylated on the methylene group next to the benzene ring and produced the...

Abstract Medicinal plants are used by the practitioners and pharmacologists to prevent and cure many diseasesMedicinal plants are used by the practitioners and pharmacologists to prevent and cure many diseases for the last several thousand years. Tulsi is known as “Queen of plants” “The mother medicine of nature”. Tulsi i.e. Ocimum sanctum is a plant with enormous properties for curing and prev...
