AB  - BACKGROUND:  and objectives Quinoa is considered to be a "natural functional food" due to a lot of bioactive compounds that are beneficial for human health by helping prevent the risks of different diseases. The aim of this study was to test the health-promoting characteristics of Puno and Titicaca quinoa seeds grown in Serbia by assessing their phenolic and flavonoid content, antioxidant activities, and potential anticancer effect on human colorectal cancer cells. Findings Thirteen phenolic compounds were identified and quantified in the seeds of both cultivars, but their profile and concentration of individual phenolic compounds differed. Cytotoxic activities were present in both cultivars, whereas the pronounced concentration and time-dependent effects were more expressed in Puno extracts. Conclusions The extracts of the seeds of both cultivars are a rich source of phenolic and flavonoid compounds and with high antioxidant activities. Potent anticancer activity against the human colorectal cancer was expressed in both investigated cultivars. Significance and novelty The study confirmed the health benefit potential of Puno and Titicaca quinoa cultivars, grown in Serbia. These results are the first to demonstrate a potent anticancer activity of quinoa seed extract against the human colorectal cancer cell line HCT-116, as well as the presence of 7 new phenolic and flavonoid compounds.

AB  - Vranac, an old autochthonous red grapevine variety of Montenegro, was first mentioned in a historical document published in the 15th century. As currently the study of indigenous varieties is of particular importance, the subject of this work was detailed characterization of phenolic compounds in the autochthonous grapevine variety Vranac, from the Montenegrin Podgorica subregion. Phenolic profiles of leaves, berries (skin, seeds, and pulp were examined separately) and young monovarietal wine were determined using ultra-high performance liquid chromatography (UHPLC) with linear trap quadrupole (LTQ)-Orbitrap XL mass spectrometry (MS). Total phenolic content (TPC) and radical scavenging activity (RSA) were higher for the grape seeds extracts, followed by extracts of grape skins and pulps. As expected, the total anthocyanin content (TAC) was higher in grape skin than in wine. A total of one hundred twenty nine compounds (forty two phenolic acids and their derivatives, twenty three flavan-3-ols, twenty one flavanols, five stilbenes and thirty eight anthocyanins) were identified in the investigated extracts. To our best knowledge, this is the first report of tentative identification of (epi)catechin 3-O-coumarate in grape seed and chalcan-flavan 3-ol dimers in wine and grape seed.

AB  - Nepetalactones are accumulated as the main secondary metabolites in the majority of Nepeta species; however, their biosynthetic pathway remains to a great extent unknown, as well as their relationship to the overall physiology of these plants. Nepetalactones most certainly arise through general iridoid biosynthetic pathway leading to nepetalactol, a common precursor of all plant-derived iridoids that is formed in a reaction catalysed by iridoid synthase (IS, EC 1.3.1.99). In this paper, we aimed to localize the sites of nepetalactone biosynthesis and accumulation by comparatively analysing the nepetalactones content and the expression of putative iridoid synthase (NrIS) in leaves of Nepeta rtanjensis Diklic & Milojevic, a trans,cis-nepetalactone and dehydronepetalactone rich species. Another aim was to give an insight into the developmental regulation of nepetalactone biosynthesis in leaves of cultivated N. rtanjensis plants. Knowledge on the spatial-, and developmental regulation of nepetalactone metabolism could greatly benefit potential growers by enabling them to adequately plan and manage plant cultivation, harvesting, and handling and thus increase yield of bioactive compounds. The expression profile of putative NrIS1 is highly correlated with trans,cis-nepetalactone and dehydronepetalactone content/ratio in leaves of different developmental stages. The results strongly indicate that developmental regulation of nepetalactone biosynthesis in leaves resides largely at the level of gene expression, and suggest an important role of NrISI. Young leaves exhibited the most intensive nepetalactone biosynthesis and accumulation, but also its conversion to dehydronepetalactone. Thus, the pattern of NL accumulation in leaves can be explained by both the rate of its biosynthesis and metabolic degradation. The gene expression patterns of NrIS1 and NrIS2 transcripts in trichomes and abraded leaves revealed trichomes as the main site of their activity. UHPLC/qqqMS profiling of nepetalactones in trichomes and abraded leaves, complemented with Raman spectroscopy and dichloromethane dipping experiment, supported glandular trichome-specific localization of nepetalactone biosynthesis and accumulation.
