A procedure to identify dihydroflavonol (glucosides), cinnamic acids and anthocyanins in flowers of Petunia hybrida is presented. Nearly all known intermediates and anthocyanins ocurring in Petunia are separated on one column using different elution systems. Hydrolysis of extracts before HPLC and thin layer chromatography is in some cases necessary to make positive identification of flavonoids....

Vaccinium berries contain high yields of antioxidant compounds, such as flavonoids and carotenoids, which are recognized to benefit human health. Therefore, commercial interest in cultivated and wild Vaccinium berries is increasing globally. Flavonoids and carotenoids are important secondary metabolites, the biosynthesis of which is regulated by interaction of the genetic background of the plan...

background: bio-stimulators as biological substances stimulate metabolism and metabolic processes, which can be increase plants yield and secondary metabolites content. objective: the aim is to introduce bio-stimulators as bioactive amino acid compounds to increase yield and help to sustainable agriculture. methods: this experiment was conducted at acecr on the base of randomized complete block...

Flavonoids are a significant group of secondary metabolites in plants. Many of these compounds are potent antioxidants, being an important part in food products derived from the plants. The current status of research on flavonoid compounds in the fruit of Saskatoon berries (Amelanchier alnifolia Nutt.) and their health promoting effects, including recommended utilization, are reviewed. The majo...

Abstract Salicornia europaea L. is a common halophytic plant species distributed in many saline soils and habitats, including margins of many wetlands. Salicornia europaea grows around Mighan Wetland, a natural desert ecosystem in central Iran with fluctuating water levels due to constant heat and severe wind throughout the year. Although, aspects of biology and ecology of halophytes growi...

This study identified major phenolic compounds of the tucum-do-cerrado (Bactris setosa) peel, as well as antioxidant activity and total phytochemical compound concentration of different extracts of the peel and pulp of this fruit. Phenolic compounds of the different extracts of tucum-do-cerrado peel were identified and quantified using a high-performance liquid chromatography system coupled to ...

BACKGROUND Canadian prairies are a habitat for unique wild plants. The main object of the present study was to investigate phytochemicals content and antioxidant activity in seven wild Canadian prairie fruits. METHODS The presence of total phenolics, flavonoids, anthocyanins and antioxidant activity were identified in the extracts according to standard procedure. RESULTS Wild rose had the h...

The growth regulator, PIX (mepiquat chloride l,l-dimethyl-piperdinium chloride), when applied to cotton (Gossypium hirsutum L.) and pecan (Carya illinoensis Koch), caused internode shortening. PIX did not elicit an increase in resistance in cotton to the tobacco budworm[Heliothis virescens (Fab.)], or in pecan to pecan scab (Cladosporium caryigenum (Ell. et Lang) Gottwald]. Also, changes in con...
