Phytotherapeutical properties of blackthorn (Prunus spinosa L.) are well known and used in Bosnia and Herzegovina traditional medicine. This study aimed to investigate total phenolic content, total anthocyanin content, total flavonoid content, antioxidant and antibacterial activities of different ethanolic extracts from wild blackthorn flowers, leaves and fruits, obtained by microwave-assisted extraction and ultrasound-assisted maceration. The mineral profile has been identified using flame atomic absorption spectrophotometry. Plant samples were collected from three areas in Bosnia and Herzegovina. In order to detect antioxidant activity of extracts, DPPH assay was carried out. DPPH radical scavenging activity was higher for flower and fruit extract than leaf extracts, regardless of the extraction method used. Ethanolic extracts show significant antimicrobial activity against all analyzed bacterial strains (Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Salmonella enterica, Escherichia coli, Pseudomonas aeruginosa and antifungal activity against Candida albicans). Blackthorn fruits contained high mass fractions of some essential minerals on dry mass basis, including K, Ca, Mg, Na, Fe, and Cu. Blackthorn flower, leaf and fruit extracts exhibit a high...

Several spectrophotometric and HPLC methods for the determination of lornoxicam and eperisone hydrochloride have been documented individually or in combination with other drugs in pharmaceutical dosage forms. Therefore, in the present study, a reasonable and practical reverse phase HPLC method was developed and validated for lornoxicam and eperisone hydro-chloride in bulk formulation. In RP-HPLC method, the analyte was resolved by using an isocratic system, Methanol: Water (55:45) with 0.1% v/v Ammonium Hydroxide, pH 7.4 was used as mobile phase, at a flow rate of 1.0 ml/min, on HPLC system containing C18 analytical column (25 × 0.46 cm, 5 µm). The detection was carried out at 274 nm. The retention time was found to be 7.4 min and 9.2 min for lornoxicam and eperisone hydrochloride, respectively. Good resolution and retention time were observed. The results of the analysis in the method were validated with respect to following parameters linearity, precision, specificity and system suitability, limit of detection and limit of quantification....

Bacterial infections are one of the prominent causes of health problems and mortalities around the world. Medicinal plants are a rich source of antimicrobial agents and provide a safer and cost-effective way of treating bacterial infections. The objective of the present investigation was to evaluate the anti-bacterial potential of petroleum ether and methanol extracts of Anacardium occidentale L. leaf. The anti-bacterial potential of A. occidentale L. leaf was tested against gastrointestinal tract infection-causing bacteria such as Escherichia coli, Shigella flexneri, Enterococcus faecalis, Vibrio cholariae, Staphylococcus aureus, Klebsiella pneumoniae, and Salmonella typhi by using the agar well diffusion method. Streptomycin was taken as the reference antibiotic. The results indicated that petroleum ether extract of A. occidentale L. exhibited the highest zone of inhibition against Shigella flexneri (26±0.75) and least against Staphylococcus aureus (11±1.32). In contrast, methanolic extract exhibited the highest zone of inhibition on Vibrio cholariae (20±1.41) and least against Escherichia coli (11±0.21). The preliminary phytochemical analysis revealed the presence of alkaloids, glycosides, tannins and polyphenolic compounds, flavonoids, saponins, steroids,...

Carbohydrate-based therapeutics are extremely potent, and many carbohydrate-based drugs are in the stage of preclinical or clinical trials. There is a growing interest in developing carbohydrate analogues for novel drug discovery as most of the recently used carbohydrate drugs display significant pharmacological activities and low toxicity. Also, the search for an antipyretic drug is a never-ending challenge. This research aimed at the development and synthesis of a series of amide-linked sugars (PV1-PV20) by coupling brominated sugars with varying amino acids coupled with nicotinic acid (GP1-GP10). Characterization of the derivatives synthesized was done by Infrared and Nuclear Magnetic Resonance Spectroscopy. These congeners were tested to analyze their antipyretic potential, and eight analogs out of twenty showed significant antipyretic activity. Thus, the carbohydrate-based amide derivatives show important action in obstruction and therapy of fever. Further work on these lines may play an important role in maintaining good health at a low...

Genus Curcuma L. ( Zingiberaceae), comprising of 120 species, is distributed throughout South and South-East Asia, with few species extending to China, Australia, and South Pacific. Four species of Curcuma are reported from Melghat. Of these C. longa L. is cultivated while C. inodora Blatt., C. pseudomontana J. Graham and C. decipiens are wild. C. decipiens being rare could not be collected. Curcuma inodora Blatt. Known as ‘Jangali Halad’ is a common herb of Melghat at higher elevations. In the Melghat area, populations of C. inodora are found to show many distinct variations in aerial as well as underground characters. Twelve distinct variants of C. inodora and C. pseudomontana and C. longa were collected. HPTLC screening of free amino acids showed the presence of four to eleven amino acids in Curcuma inodora accessions, while in C. pseudomontana and C. longa, ten amino acids each were found. Glycine and Proline were found in all samples studied. Amino acid composition is specific for each species and variants; hence can be used...
