Chemical composition and bioactive properties of: Sanguisorba minor Scop. under Mediterranean growing conditions

Kiwis are an example of fruits with excellent bioactive properties worldwide appreciated and consumed generating tons of waste. Thus, the objective of this work was to compare two varieties of kiwi: Actinidia deliciosa cv. “Hayward” (green) and Actinidia spp. (red) regarding the nutritional value of their pulps, chemical composition and bioactivities of each pulp and peel. The results revealed that pulps have a high water content and low amount of other macronutrients. Both parts of red kiwi presented the highest tocopherols content and red kiwi pulp presented the highest content in ascorbic acid. In general, the peels exhibited the highest antioxidant activity and green kiwi peels showed cytotoxicity and anti-inflammatory activity, which could be related to its higher content in phenolic compounds, especially B-type (epi)catechin dimer. Therefore, kiwi components currently underutilized may be indicated as a source of natural functionalizing ingredients with several benefits for human health.info:eu-repo/semantics/publishedVersio

Sanguisorba officinalis L., an alternative source of phenolic compounds and remarkable bioactivities

Sanguisorba officinalis L. or great burnet, belongs to the Rosaceae family and it is a perennial plant widely distributed throughout Europe,Asia and North America (1). It is well known as a traditional herbal medicine due to its bioactive compounds content (2). This study aimed to evaluate the phenolic profile and bioactives of leaves and roots od S. officinalis plants were cultivated in central Greece, using different types of fertilizers, namely: i) control - without fertilization (A: leaves; B: roots); ii) inorganic fertilizer at a rate of 330 kg/ha (C: leaves; D: roots); and iii) inorganic fertilizer at a rate 660kg/ha (E: leaves; F: roots): Phenolic compounds were identified and quantified by HPLC-DAD-ESI/MSn. Four Gram-negative and four Gram-positive bacteria, and six fungi were used to screen the antimicrobial activity of the samples. Cytotoxic activity was tested on tumor cell lines of MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer), HeLa (cervical carcinoma), HepG2 (hepatocellular carcinoma) and a non-tumor cell line (PLP2).support to CIMO (UID/AGR/00690/2019); L.
