With the increasing attention to the health promoting activities of the bioactive compounds from some plants, many researchers are focusing on the biological potential and mechanisms of certain cultivated plant species. In this review, we survey the olive and almond based extracts specific phytoconstituents and their associated health promoting effects that have been evaluated in experimental and clinical studies.

La biomasa leñosa como recurso energético varía según tres factores: 1) especie, 2) condiciones ambientales que influyen en su producción y 3) dispersión en el territorio. La estimación de la aptitud de este recurso es crucial para el desarrollo sustentable del sector agroforestal y, en concreto, de la cadena de valor bosque-industria-consumo. Tomando en cuenta esta situación, el objetivo de este documento consistió en determinar la aptitud de tres tipos arbóreos como biocombustible sólido. Una especie forestal (Quercus ilex), un cultivo energético (Paulownia spp.) y tres especies frutales Citrus sinensis (naranjo), Olea europaea (olivo) y Prunus amygdalus (almendro). Para alcanzar este objetivo, la investigación se centró en la caracterización física, química y energética de la biomasa leñosa de estas especies. Con base en un muestreo representativo, los resultados obtenidos sirvieron para determinar de forma cualitativa las aptitudes y limitaciones de estas especies como biocombustible sólido.Los principales resultados demuestran que la biomasa de cada especie estudiada es apta para su uso energético como biocombustible sólido, con la excepción de la madera de naranjo que presenta algunas limitaciones para la fabricación de pellets.

Olea europaea germplasm is constituted by a huge number of cultivars, each one characterized by specific features. In this context, endemic cultivars evolved for a very long period in a precise local area, developing very specific traits. These characteristics include the production and accumulation of phytochemicals, many of which are also responsible for the nutraceutical value of the drupes and of the oils therefrom. With the aim of obtaining information on the phytochemical profile of drupes of autochthonous cultivars of Cilento, Vallo di Diano and Alburni National Park, a metabolomics-based study was carried out on 19 selected cultivars. Multivariate data analysis of 1H-NMR data and 2D NMR analyses allowed the rapid identification of metabolites that were qualitatively and/or quantitatively varying among the cultivars. This study allowed to identify the cultivars Racioppella, Guglia, Pizzulella, Oliva amara, and Racioppa as the richest in health-promoting phenolic compounds. Furthermore, it showed a significant variability among the different cultivars, suggesting the possibility of using metabolic fingerprinting approaches for cultivar differentiation, once that further studies aimed at assessing the influence of growing conditions and environmental factors on the chemical profiles of single cultivars are carried out.

Many indigenous Korean plants have been used in medicinal preparations and health-promoting foods. These plant species contain beneficial metabolites with various bioactivities, such as antioxidant and anti-inflammatory activities. Herein, we suggest a new screening strategy using metabolomics to explore the bioactive compounds in 50 Korean plants. Secondary metabolites were analyzed using UHPLC-LTQ-Orbitrap-MS/MS. The plant extracts were subjected to antioxidant and anti-inflammatory assays. We identified metabolites that contributed to bioactivities according to the results of bioassays and multivariate analyses. Using Pearson’s correlation, phenolics (e.g., casuarictin, 3-O-methylellagic acid) showed positive correlation with antioxidant activity, while biflavonoids (e.g., amentoflavone, rosbustaflavone) were correlated with nitric oxide (NO) inhibition activity. To compensate for the limitation of this new strategy, we further validated these by investigating three parts (branches, fruits, leaves) of Platycladus orientalis which showed high activities on both bioassays. Unlike the above observation, we identified significantly different metabolites from different parts, which was not the results of bioassays. In these validation steps, interestingly, biflavonoids (e.g., robustaflavone, sciadopitysin) contributed to both activities in P. orientalis. The findings of this work suggest that new strategy could be more beneficial in the identification of bioactive plant species as well as that of their corresponding bioactive compounds that impart the bioactivity.

The intracellular distribution of chloroplasts in the mesophyll was studied in leaves taken from seven plant species from different groups: the evergreen sclerophylls Olea europaea and Nerium oleander; the drought semideciduous and seasonally dimorphic shrub Coridothymus capitatus; the winter deciduous Capparis spinosa, which grows entirely during summer; and the cultivated species Hordeum vulgare, Vigna unguiculata, and Citrus aurantium. In all leaves and mesophyll types, chloroplasts were found to line the parts of the walls exposed to the internal leaf atmosphere. The arrangement of the chloroplasts adjacent to intercellular air spaces might be a universal phenomenon facilitating the inward diffusion of CO2.

Leaves from Olea europaea represent one of the main by-products of the olive oil industry, containing a plethora of bioactive compounds with several promising activities for human health. An organic solvent-free extraction method was developed for the recovery of olive leaf phenols, which obtained an extract containing oleuropein in high amounts. A comparison of various extraction media is reported, together with the total phenolic content, DPPH (2,2-Diphenyl-1-picrylhydrazyl) content, ORAC (oxygen radical absorbance capacity), and polyphenol oxidase activity of the corresponding extracts. The polyphenol profiles and content of the most representative extracts have also been studied. Extraction solvent and temperature significantly influenced the phenolic content and antioxidant activity of the extracts, with hot water representing the solvent of election for the extraction of bioactive compounds from this matrix. All the extracts obtained showed reasonably high total phenol content (TPC) and good DPPH radical scavenging activity; among them, the water extract is characterized by desirable traits and could be used for many industrial applications and human consumption.
