  Objective: Continued resistance toward the antibiotics urges us to explore newer antibiotics. Plants are being the safer source of antibiotics with lesser or no side effects. This study was designed to study the presence of phytochemical constituents and antibacterial activity of leaf and flower extracts of Wedelia glauca against urinary tract infection causing pathogens.Methods: The plant leaves were extracted with five different solvents based on the polarity. The extraction was done using soxhalation. Antimicrobial activity was determined by agar well diffusion method for both the sample and standard. The acetone plant extract was subjected to gas chromatography-mass spectrometry (GC-MS) analysis for screening phytoconstituents.Results: Preliminary phytochemical screening revealed the presence of diverse phytoconstituents in the plant. The different extracts exhibited a considerable antimicrobial potential. Among the solvents used acetone extract showed comparably better antimicrobial activity with 100% of inhibition rate with the maximum zone of inhibition of 1.6±0.77 mm against Staphylococcus sp. and Aspergillus sp. at the concentration of 5 mg. GC-MS analysis provided 8 major peaks which revealed the existence of a variety of bioactive compounds which may attribute to the efficacy of the plant.Conclusion: W. glauca leaf and flower extracts displayed a broad spectrum of antibacterial and antifungal activity and can be considered as a potential source of newer antibiotic compounds.

AbstractBlood pressure regulation is basically control of amount of blood flow to certain tissues according to their metabolic needs. The complexity of the mechanisms involved leading to the assumption that there are many functional and structural proteins involved in blood pressure regulation. Indonesian people, especially those living on the island of Java, usually consume star fruit Averrhoa carambola to reduce blood pressure, but the content of bioactive compounds and the mechanism of their interference with proteins is still unknown. This study aimed to determine the bioactive compound content of Averrhoa carambola's methanol extract and its mechanism of interference with the target proteins. An amount of 200 g Averrhoa carambola dried simplicia was extracted by the maceration method using absolute methanol. The extract was then subjected to phytochemical tests using the Gas Chromatography-Mass Spectrometry (GC-MS) method. Based on the results obtained from the GC-MS phytochemical test, the names of the bioactive compounds found in the Averrhoa carambola methanol extract were obtained. The compounds are then analyzed for their target protein in the human body using the STITCH database (http://stitch.embl.de/). The proteins that had been predicted to be the target of active compounds of Averrhoa carambola methanol extract were analyzed for interactions between proteins using the STRINGdb database (https://string-db.org/cgi/input.pl). Based on this research, it can be concluded that Averrhoa carambola fruit methanol extract can help lower blood pressure by producing NO and acting as antioxidants. However, further research (in-vitro and in-vivo) needs to be done to prove the mechanism. AbstrakRegulasi tekanan darah adalah jumlah kontrol aliran darah ke jaringan tertentu sesuai dengan kebutuhan metabolismenya. Kompleksnya mekanisme yang terlibat, memunculkan asumsi terdapat banyak protein fungsional maupun struktural yang terlibat dalam regulasi tekanan darah. Masyarakat Indonesia, terutama yang tinggal di pulau Jawa biasa mengkonsumsi buah belimbing untuk menurunkan tekanan darah, namun kandungan senyawa bioaktif dan mekanisme intervensinya terhadap protein-protein belum diketahui. Tujuan penelitian ini adalah untuk mengetahui kandungan senyawa bioaktif ekstrak metanol buah Averrhoa carambola dan mekanisme intervensinya terhadap protein-protein targetnya. Simplisia kering buah Averrhoa carambola sebanyak 200 g diekstraksi dengan metode maserasi menggunakan metanol absolut. Dari ekstrak tersebut dilakukan uji fitokimia dengan metode Gas chromatography–mass spectrometry (GC-MS) sehingga didapatkan nama-nama senyawa bioaktif yang terdapat pada ekstrak metanol Averrhoa carambola. Senyawa-senyawa tersebut kemudian dianalisis protein targetnya dalam tubuh manusia menggunakan database STITCH (http://stitch.embl.de/). Kemudian dianalisis interaksi antar protein menggunakan database STRINGdb (https://string-db.org/cgi/input.pl). Berdasarkan penelitian ini, ekstrak metanol buah Averrhoa carambola dapat membantu menurunkan tekanan darah dengan memproduksi NO dan berperan sebagai antioksidan. Namun, penelitian lebih lanjut (in-vitro dan in-vivo) perlu dilakukan untuk membuktikan mekanismenya

Catharanthus roseus (periwinkle) is a medicinal plant commonly known for its wide biological activity. In many countries different parts of this plant are used for the treatment of diabetes, hypertension and for menstrual regulation. Due to the ability of production of alkaloids, which can be applied in cancer therapy, is still extensively investigated. Two, the mostvaluable alkaloids (vincristine and vinblastine) are present in C. roseus in very low concentrations. Micropropagation is promising technique used to enhance the level of important secondary metabolites. The main objective of present study was alkaloids extraction from plants cultivated conventionally and derived from in vitro cultures. In this order the aerial parts of periwinkle were extracted with 96% ethanol at room temperature (method I) and heated with 96% ethanol at 55 °C for 90 minutes (method II). The obtained mixtures of different indole alkaloids were analyzed by gas chromatography – mass spectrometry (GC-MS). Analysis revealed the presence of 15 alkaloids, among which vindoline,vindorosine,isovindolinineand ajmalicine were the most abundant. The obtained results indicated that the propagation method had a significant effect on the percentage content of alkaloids in C. roseus herb. Plants derived from in vitro cultures were richer in vindorosine and vindoline, while conventionally cultivated – in tetrahydroalstonine and ajmalicine. Moreover, in case of isovindolinine,vindolinine and ajmalicine, extraction at 55 °C was more effective, while for pericyclivine – maceration at room temperature.Interestingly, the pericyclivine was not detected in the mixture of alkaloids obtained from periwinkle herb by the extraction at55 °C.

Background: As a result of high percentage of women infected with urinary tract infection (UTI) annually, many rural dwellers use Adansonia digitata fruit pulp as herbal cure. Adansonia digitata L. (Malvaceae) is one of the great trees idolised in Africa because of its therapeutic properties.Aim: This study aimed at identifying chemical compounds in the ethylacetate fraction of the baobab fruit pulp and indicated their biological activities to justify its use for the folkloric treatment of UTI.Methods: The crude extract from Baobab fruit pulp was partitioned and ethylacetate extract was used for assay. Gas chromatography-mass spectrometry (GC–MS) analysis was performed to identify the bioactive compounds in the ethylacetate fraction, antioxidant activity was evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays whilst the total phenolic and flavonoid contents were determined by already adopted protocols. The antibacterial properties were tested against some urinary tract pathogens using macro broth dilution method.Results: A total of 36 bioactive compounds were identified by GC–MS analysis, most of them have been reported as antibacterial, antioxidant, antidiabetic, antiasthma, antifungal, anti-inflammatory and anti-cancer agents. The extract exhibited highest activity against Pseudomonas aeruginosa American Type Culture Collection (ATCC) 19582 (1.22 mg/mL) whilst Escherichia coli ATCC 8739 (˃ 8.6 mg/mL) displayed high level of resistance amongst the five bacterial isolates used in this study.Conclusion: These findings indicated that the extract contained bioactive compounds of therapeutic importance with significant antioxidant and antibacterial potentials and justify the folkloric use of this fruit in the treatment of UTIs by many African dwellers.
