Objective: This study aims to assess the phytochemical composition and antioxidant activity of the fruits (pulp and seeds) of Boscia senegalensis from the Ferlo zone in Northern Senegal. Material and Methods: Fruit collection of Boscia senegalensis was carried out in three Ferlo{\textquoteright}s localities: Tess{\'e}k{\'e}r{\'e}, Labgar and Ran{\'e}rou. The sample consists of 36 individuals selected randomly from each locality. The major chemical groups were determined by conventional methods using specific general reagents. The determination of total polyphenols and total flavonoids, the 2,2-diphenyl-1picrylhydrazyl (DPPH.) radical scavenging activity and ferric reducing of antioxidant power (FRAP) were evaluated by spectrophotometry. Results and Discussion: The results of the photochemical screening revealed the presence of saponins, alkaloids, sterols and triterpenes, flavonoids and polyphenols in both parts of the fruit (pulp and seeds). Assays carried out on extracts of pulp and seed powders reveals higher levels of total polyphenols and flavonoids in the pulp. The study of antioxidant activity has shown that hydro-ethanol extracts of pulp and seeds have a very interesting reducing activity, particularly in the pulp. However, we can see a weak antiradical activity of these extracts. The origin effect has a weak influence on the antiradical and reducing activity of the pulp and seed extracts. Conclusions: The biological activity of the harvested Boscia senegalensis extracts highlighted in this study could justify the traditional uses of this plant in the treatment of several pathologies. This fruit should be consumed in order to prevent few dietary imbalances or valorized in order to develop new bioactive compounds.

Background: Terminalia bellerica belonging to family combretaceae is one of the major components of {\textquotedblleft}Triphala{\textquotedblright}, an Ayurvedic formulation. Objective: To evaluate antioxidant potential in the ethanolic extract and its active fraction (chloroform, ethyl acetate, n- butanol and aqueous fraction) from fruits and leaves of Terminalia bellerica. Materials and Methods: Folin-Ciocalteau method and aluminium chloride method was used to quantify total phenolic and flavonoid content respectively in ethanolic extract and their fractions from fruits and leaves of T. bellerica. The antioxidant activity was evaluated using total antioxidant activity, DPPH, FRAP and total antioxidant activity methods. Results: Total phenolics (254.72{\textpm}3.03 mg/g GAE and 227.52{\textpm}1.38 mg/g GAE) and flavonoids (64.77{\textpm}1.24 mg/gm RE and 75.57{\textpm}1.38 mg/gm RE) content was higher in ethyl acetate fraction of both fruits and leaves sample of T. bellerica, respectively. The order of free radical scavenging activities was ethyl acetate fraction \> crude ethanolic extract \> n-butanol fraction \> chloroform fraction \> aqueous fraction. Similarly, ethyl acetate fraction of both fruits and leaves exhibited more antimicrobial activity as compared to that of ethanolic extract as revealed from agar well diffusion method with diameter of zone of inhibi{\textlnot}tion of 14.0{\textpm}1.41 mm, 21.0{\textpm}1.41 mm, 14.0{\textpm}1.41 mm, 14.5{\textpm}0.71 mm in fruits and 18.0{\textpm}1.41 mm, 22.5{\textpm}2.12 mm, 15.5{\textpm}2.12 mm, 14.5{\textpm}3.53 mm in leaves against B. subtilis, S. aureus, E. coli, K. pneumoniae, respectively. MIC values for fruits were 3.125 mg/ml, 0.375 mg/ml, 3.125 mg/ml, 3.125 mg/ml and for leaves were 1.5625 mg/ml, 0.19 mg/ml, 0.78 mg/ ml, 0.78 mg/ml against B. subtilis, S. aureus, E. coli, K. pneumoniae, respectively. Conclusion: The present study provides the evidence for comparative antioxidant and antibacterial potential of ethanolic extracts of fruits and leaves of T. bellerica. . Moreover, leaves can be promoted to be used for therapeutics and natural antioxidants.

Background: Light microscopic analysis is appropriate pharmacopoeial method for quality control of fresh and fast-frozen Rosaceae family plants fruits. It is widely used for crude herbal drugs analysis and helps to identify significant anatomical and diagnostic signs. The aim of the research was to establish the identity characteristics of the dried and frozen fruits of mountain ash and bird cherry and to perform phytochemical analysis of studied objects harvested in Moscow. Materials and Methods: Light microscopic analysis was used for Rosaceae fruits identity estimation. The fruits of mountain ash (Sorbus aucuparia L.) and bird cherry (Padus avium Mill.) were collected in the fruiting phase on the territory of the Botanical Garden of Sechenov First Moscow State Medical University. Fruits samples were dried at the temperature of 60-80{\textdegree}C and frozen at the temperature of -18-20{\textdegree}C. The epidermis surface preparation and the fruit pulp squash preparation were prepared for microscopic examination. The photographs were obtained from an AXIO IMAGER D1 biological laboratory microscope (Carl Zeiss Microscopy) with the help of a Canon Power shot A 650 IS camera. The elemental composition of the P. avium and S. aucuparia fruits was determined by X-ray fluorescence analysis (XFA) using an S4 Pioneer X-ray spectrometer. Simple sugar analysis was performed by using reverse phase HPLC with refractometric detection, analysis of organic acids {\textendash} by using ion-pair HPLC with UV-detection (210 nm) in the isocratic elution mode (Agilent 1260 Infinity LC). Results: Characteristic signs of the anatomical structure of dried and frozen S. aucuparia, P. avium fruits were determined. Diagnostic anatomical signs of S. aucuparia, P. avium fruits are: the form of epidermal cells, stone cells, inclusions of calcium oxalate (prismatic crystals and druses), vessels, parenchyma with biologically active substances (anthocyanins, carotenoids). The presence and content of Na, Mg, Al, Si, P, S, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr were evaluated. Organic acids profile of S. aucuparia, P. avium fruits is presented by citric, malic, oxalic, succinic, tartaric, fumaric, quinic, ascorbic, sorbic acids. Total content of simple sugars, presented by glucose, fructose, sucrose, is in the interval of 8-9\%. Conclusion: The results of a comparative microscopic analysis of bird cherry and mountain ash dried and frozen fruits were obtained. They allowed to identify diagnostically significant elements of the anatomical structure that can be used to establish the fruits identity. The obtained data is of great value for S. aucuparia, P. avium fruits pharmacopoeial analysis in the Russian Federation.

The comparative morphological and anatomical research of the fruits and seeds of two species of the genre Lycium is conducted. An objective of this research was carrying out comparative studying of anatomical diagnostic signs of fruits of a red Godjy berries (Lycium barbarum L.) and black Godjy berries (Lycium ruthenicum murr.) for establishment of authenticity of medicinal vegetable raw materials. This work is a fragment of complex researches of plants of flora of the North Caucasus and also introduced species. Because of the conducted comparative this research the main signs allowing to carry out identification of medicinal vegetable raw materials both in integral and in the crushed look are revealed. The conducted researches can be used further for development of normative documentation on raw materials of these species.
