Recently, the fingerprint approach using chromatography has become one of the most effective tools for quality assessment of herbal medicines and food supplements: due to the complexity of the chromatographic fingerprint and the irreproducibility of chromatographic instruments and experimental conditions, chemometric approach is employed to deal with the(More)
Centuries of co-evolution between Castanea spp. biodiversity and human populations has resulted in the spread of rich and varied chestnut genetic diversity throughout most of the world, especially in mountainous and forested regions. Its plasticity and adaptability to different pedoclimates and the wide genetic variability of the species determined the(More)
UNLABELLED CONTEXT. Ribes nigrum L. (Grossulariaceae) is among the most commonly used herbal medicines and it is popularized for its alleged tonic effect and curative and restorative properties. The current practice of identifying herbal extracts is by measuring the concentration of the main botanicals. Their concentrations are used to characterize the(More)
BACKGROUND Many plant species may be used for the production of herbal preparations containing phytochemicals with significant antioxidant and anti-inflammatory capacities and health benefits: Castanea spp. is among the most commonly used herbal medicines. The aim of this research was to perform an analytical study of chestnut bud preparations, in order to(More)
It is well known that plants are important sources for the preparation of natural remedies as they contain many biologically active compounds. In particular, polyphenols, terpenic compounds, organic acids, and vitamins are the most widely occurring groups of phytochemicals. Some endemic species may be used for the production of herbal preparations(More)
BACKGROUND The raspberry, Rubus idaeus L., provides several plant parts (as buds) used for food supplements. The aim of this research was to establish a technique for chemical composition control of R. idaeus herbal preparations, using chromatographic methods. These methods allowed us to identify and quantify the main phytochemicals, obtaining a specific(More)
Cactus pear is the common name of Opuntia ficus-indica (L.) Mill., the arid-resistant plant that is grown worldwide for its multifunctional proprieties. The paper gives an overview of local genetic resources of Opuntia spp. and describes the results of the recent introduction of some O. ficus-indica varieties, hybrids and other cactaceas on Fogo Island(More)
