 The plants of the genus Ehretia composed of about 150 species mainly distributed in tropical Asia, Africa, Australia, and North America. They have been used as traditional and folk medicines to treat various ailments in Japan, India, and China for a long time. Previous phytochemical screenings demonstrated that the Ehretia plants mainly contain fatty acids, phenolic acids, flavonoids, cyanogenetic glycosides, and benzoquinones and other constituents from different chemical classes. The pharmacological studies confirmed that the crude extracts or individual compounds from the genus showed antioxidant, anti-inflammatory, antibacterial, antiarthritic, antitubercular, and antiallergic activities, as well as anti-snake venom property. In this review, we presented a summary of the secondary metabolites isolated from different species of Ehretia based on the published literatures up to March 2017. In addition to the traditional medicinal use of Ehretia plants, we focused on the known biological activities of the plants and discussed them in detail here.

AbstractFungi are well known for their ability to synthesize secondary metabolites, which have proven to be a rich resource for exploring lead compounds with medicinal and/or agricultural importance. The genera Aspergillus, Penicillium, and Talaromyces are the most widely studied fungal groups, from which a plethora of bioactive metabolites have been characterized. However, relatively little attention has been paid to the genus Paecilomyces, which has been reported to possess great potential for its application as a biocontrol agent. Meanwhile, a wide structural array of metabolites with attractive bioactivities has been reported from this genus. This review attempts to provide a comprehensive overview of Paecilomyces species, with emphasis on the chemical diversity and relevant biological activities of these metabolic products. Herein, a total of 148 compounds and 80 references are cited in this review, which is expected to be beneficial for the development of medicines and agrochemicals in the near future.

The use of plants for medicinal purposes is performed empirically by traditional knowledge with the use of preparations that seek to extract their active principles, and are considered to be fundamental to human health. In this context, the aim of the present study was to of this study was to carry out a systematic review of the biological activities of the Arecaceae family distributed throughout Brazil. This research was carried out through a comprehensive search using the following databases, Scopus, Portal Periódicos Capes, PubMed, Google Scholar and Science Direct, using the following descriptors: “Arecaceae” and “Biological properties of the family Arecaeae”, checked at <www.theplantlist.org/> to check synonyms. It was possible to identify numerous biological activities in the arecaceae family, among the most recurring ones, the antioxidant, antimicrobial and anti-inflammatory activity. These activities are justified by the presence of fatty acids, phenolic compounds, alkaloids and terpenes. Studies routinely report lauric acid as a major in the plants of this family, which makes it a potential compound to cure or assist in the treatment of various diseases.

SummaryWe performed a systematic review of randomized placebo-controlled pharmacological and non-pharmacological trials for the therapy and prevention of post-stroke depression that have been published between 1980 and 2011. We initially identified 2 260 records of which 28 studies were finally included into this review. A meta-analytic approach was hampered by considerable differences regarding the kinds of therapeutic regimens and the study durations. Modest effects favoring treatment of post-stroke depression could be found for pharmacological treatment as well as repetitive transcranial magnetic stimulation. For the prevention of post-stroke depression, antidepressant pharmacotherapy showed promising results. However, large-scale studies with better standardized study populations, optimized placebo control procedures in non-pharmacological studies, and replication in larger follow-up studies are still necessary to find the optimal therapeutic regimens to prevent and treat post-stroke depression.

Callus Cell

The physiological characteristics of the callus cell cultures of Alhagi persarum Boiss et Buhse, a member of the legume family, widely used in folk medicine, have been studied. It was shown that the source of the explant was an important factor in the initiation of callusogenesis: more intense callusogenesis (almost 100%) was observed for explants from various organs of sterile seedlings, rather than intact plants (less than 30%). As a result, more than 20 lines of morphologically different callus cell cultures were obtained, and the growth parameters for the 5 most intensively growing lines were determined. The composition of fatty acids (FA) of total lipids and secondary metabolites in the most physiologically stable callus line Aр-207 was analyzed. Using capillary gas-liquid chromatography with mass spectrometric detection (GLC-MS), 19 individual C12--C24 FAs were identified, the main fraction of which were palmitic (~ 23%), stearic (~ 22%), linoleic (~ 14%) and α-linolenic (~ 33%) acids. The established atypical ratio of FAs (a simultaneous high content of both saturated FAs and polyunsaturated α-linolenic acid) is possibly due to the adaptation of cells to in vitro growth conditions. Phytochemical analysis of the secondary metabolites was carried out using ultra-performance liquid chromatography with electrospray ionization mass spectrometric detection (UPLC MS). Compounds belonging to different structural groups of isoflavones were found. Aglycones (calycosin, formononetin and afrormosin isomer), glucosides (formononetin glucoside), as well as esters of glucosides (malonylglycosides of calicosin, formononetin, afrormosin isomers, glycitein and genistein) were detected. These secondary metabolites are widespread in plants of the Fabaceae family; however, isoflavones are rare in representatives of the Alhagi genus. The presence of malonylated isoflavone glycosides in Alhagi spp. was shown for the first time. endemic plant species, Alhagi, in vitro cell culture, callus cell culture, isoflavones, fatty acids All studies were carried out using the equipment of the "Experimental Biotechnological Facility" and the "All-Russian Collection of Cell Cultures of Higher Plants" of IРР RAS.
