This paper compares two medicinal species of Kalanchoe, which are often used interchangeably by the population, regarding the distribution of anthocyanins under the influence of four luminosity levels for 6 months. For the morphoanatomical analysis, the 6th stem node of each plant was sectioned. Usual histochemical tests revealed the presence of anthocyanins by cross sections of the stems, peti...

A study to establish relationship between the petal colour, extraction solvent, phenolic, flavonoid, anthocyanin content and antioxidant activity in three varieties of Viola × wittrockiana (yellow, red and violet) is reported in this article. Identification and quantification of flavonoids and anthocyanins using HPLC-DAD-ESI-MS is also presented. The antioxidant activity was studied by four dif...

abstract           background and objective: stachys inflata benth. is used as an anti-inflammatory and antiseptic agent in traditional medicine in most mountain villages of golestan province. therefore, this study aimed to investigate the antioxidant, ethnopharmacological and phytochemical properties of extract from different parts of s. inflata, collected from chahar bagh mountain.          m...

In our previous study, as natural food colorants and antioxidants, the color and content stabilities of Schisandra chinensis (S. chinensis) anthocyanins were investigated. In this work, the purification process parameters of S. chinensis anthocyanins using a macroporous resin and gel filtration chromatography were evaluated. The optimized parameters of static adsorption and desorption were as f...

Background and objectives: Capparis spinosa is a perennial herb belonging to the Capparidaceae family that is mainly distributed in arid and semi-arid regions of the tropical and subtropical world. The plant is a potential source of valuable nutrients that is valued for human food. The fruit of this plant, being a rich source of high-value components, is usually pickle...

Flavonols, anthocyanins, and chalcones were determined during the flowering phase in two genotypes of Cosmos sulphureus (regular species its cultivar ‘Cosmic Orang’) grown М.М. Gryshko National Botanical Garden Kyiv. Inflorescences, leaves, stems, roots, separated ray disc florets dried crushed to prepare extracts following three different techniques. In particular, with 80 % (v/v) ethanol Andr...

The current status of the isolation, identification, biological activity, utilization and development prospects of flavonoids found in litchi fruit pericarp (LFP) tissues is reviewed. LFP tissues account for approximately 15% by weight of the whole fresh fruit and are comprised of significant amount of flavonoids. The major flavonoids in ripe LFP include flavonols and anthocyanins. The major fl...
