Jasmine tea is a popular type obtained from scenting (Camellia sinensis (L.) Kuntze) leaves with jasmine (Jasminum sambac Aiton) flowers. This study aimed to evaluate the antioxidant properties and sensory aspects of green brewed at different times. The commercial were in boiling water ratio 1:100 for 0.5, 1, 2.5, 5, 10, 30, 60 min. was evaluated colour, pH, total flavonoid content (TFC), pheno...

Ultrasound-assisted extraction (UAE) or ultrasonic technology has been used for the isolation of bioactive compounds from Argyreia speciosa (Linn. f.) Sweet plant (family: Convolvulaceae). is an Indian traditional medicinal having strong evidence various properties widely in Ayurveda. Dried flowers were and response surface methodology (RSM) was to optimize conditions yield total phenolics anti...

To improve the production of chlorogenic acid (CGA) in hairy roots of Platycodon grandiflorum, we induced over-expression of Arabidopsis thaliana transcription factor production of anthocyanin pigment (AtPAP1) using an Agrobacterium rhizogenes-mediated transformation system. Twelve hairy root lines showing over-expression of AtPAP1 were generated. In order to investigate the regulation of AtPAP...

The essential oil was obtained by hexan. The sample oil, which was light yellow in color, was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The oil obtained was analyzed by GC-MS and GC/MS. The components of the oil were identified by comparison of their mass spectra to those of a computer library or with authentic compounds and confirmed by comp...

Phytochemical analysis of the ethanolic Jasmine flower extract of Jasminum sambac (L.) Ait. "G. Duke of Tuscany" revealed the mixtures of coumarins, cardiac glycosides, essential oils, flavonoids, phenolics, saponins, and steroids. However, alkaloids, anthraquinones, and tannins were not detected. By intravenous injection at a single dose of 0.5 mL/mouse (15 mg) of the flower extract, no system...

Due to the rising disease burden, natural plant products are becoming popular today. The Hibiscus rosa sinensis Linn., which belongs Malvaceae family, is found all over world. In India's traditional medicine, its leaves, barks, roots, and flowers have been used treat a variety of illnesses. Numerous studies demonstrated antioxidant, antimicrobial, antidiabetic, antiulcer, hepatoprotective, anti...

The flavonoids from flowers of transgenic Petunia ×hybrida Vilm. plants containing the Al gene from Zea mays L. were characterized. The A1 gene encodes the enzyme dihydroflavonol reductase and was introduced into a mutant petunia defective for this gene. Control, nontransgenic plants produced flowers that contained ≈ 50 ng anthocyanin/ 100 mg tissue dry weight. Anthocyanin distribution was 63% ...
