Bioactive plant compounds and extracts are of special interest for the development of pharmaceuticals. Here, we describe the screening of more than 1100 aqueous plant extracts and synthetic reference compounds for their ability to stimulate or inhibit insulin secretion. To quantify insulin secretion in living MIN6 β cells, an insulin–Gaussia luciferase (Ins-GLuc) biosensor was used. Positive hits included extracts from Quillaja saponaria, Anagallis arvensis, Sapindus mukorossi, Gleditsia sinensis and Albizia julibrissin, which were identified as insulin secretion stimulators, whereas extracts of Acacia catechu, Myrtus communis, Actaea spicata L., Vaccinium vitis-idaea and Calendula officinalis were found to exhibit insulin secretion inhibitory properties. Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) were used to characterize several bioactive compounds in the selected plant extracts, and these bioactives were retested for their insulin-modulating properties. Overall, we identified several plant extracts and some of their bioactive compounds that may be used to manipulate pancreatic insulin secretion.

 Objective:The objective of this study is to characterize the phytoconstituents of Tiliacora racemosa Colebr. using gas chromatography mass spectrometry (GC-MS).Methods: Preliminary phytochemical and physicochemical analysis was carried out using standard procedures. GC-MS analysis of methanolic extract was carried out using Thermo GC-Trace Ultra version: 5.0, Thermo MS DSQ with a DB 35MS capillary standard non-polar column and gas chromatograph interfaced to a mass selective detector (MS DSQ II) with Xcalibur software.Results: Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, triterpenoids, steroids, proteins and amino acids, carbohydrates, saponins and coumarin. Quinones, anthraquinones, glycosides and fixed oil were absent. GC-MS analysis revealed the presence of 28 compounds of which quinic acid (retention times [RT]: 15.65) and inositol, 1-deoxy-(CAS) (RT: 19.24) was observed as abundant compounds.Conclusion: The presence of various bioactive compounds confirms the medicinal importance and it’s application for curing various diseases by traditional practitioners. However, isolation and characterization of potential bioactive compounds would lead to drug formulation.

ABSTRACTObjective: The aim of this study was to investigate the presence of bioactive compounds in the methanolic leaf extract of Syzygium jambos.Methods: Collected leaves were shade dried and made into fine powder, extracted with methanol, and the methanolic extract was prepared andanalyzed for the presence of bioactive compounds by gas chromatography-mass spectrometry (GC-MS). The mass spectrum of the chromatographywas matched with NIST and WILEY Libraries.Results: The GC-MS analysis revealed the presence of 45 active compounds in the extract. From the GC-MS investigation, 1-Deoxy-d-mannitol3-methyl-2-methylsulfanyl-5-nitro-6-pyridin-4-ylpyrimidin-4-one, 3-Pentadecylphenol, 2-biphenylene carboxylic acid, Quinoline-3-carboxylic acid,and Stigmast-5-en-3-ol are important phytoconstituents which have antipyretic and antiparasitic activities.Conclusion: The present investigation revealed preliminary information on phytocompounds presented in S. jambos leaf extract which is very usefulfor the human community.Keywords: Syzygium jambos, Gas chromatography-mass spectrometry analysis, 1-Deoxy-d-mannitol, Phytoconstituents, Methanolic leaf extract.

Objective: The aim was to investigate important bioactive compounds, biological activities, and medicinal importance of Zanthoxylum rhetsa fruits.Methods: The present work was carried out by gas chromatography–mass spectrometry (GC-MS) method for the identification of different compounds.Result: The methanolic extract of fruits showed 32 chemical compounds which are identified through GC-MS analysis. Among them, some of the compound names and percentage values are as follows: 2-propanone, 1,3-dihydroxy (48.9%), 4H-pyran-4-one,2,3-dihydro-3,5-dihydroxy-6-methyl (33.7%), 2-furancarboxaldehyde, 5-[hydroxymethyl] (50.2%), 1-Heptatriacontanol (34.4%), 9,12-octadecadienoic acid (zz)- (48.6%), cholestan- 3-ol,2-methylene, [3β,5α] (75.0%), 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl (90.8), 2-furancarboxaldehyde, 5-[hydroxymethyl] (92.0%), hydroquinone (64.9%), n-hexadecanoic acid (37.5%), octadecanoic acid (28.2%), 9,12,15, octadecatrienoic acid, 2-[(trimethylsiyl]oxy]-1- [(trimethylsiyl]oxy]methyl] ethyl ester, [zzz] (22.6%), 9-hexadecanoic acid (10.3%), digitoxin (18.8%), 8,11,14-eicosatrienoic acid methyl ester, [zzz] (25.5%), and oleic acid (16.5%). Most of the identified compounds in the crude methanolic extracts exhibit some bioactivities, namely anticancer, anti-inflammatory, antimicrobial, hepatoprotective, antioxidant, hypocholesterolemic, nematicide, pesticide, anti-androgenic flavor, hemolytic, 5-alpha-reductase inhibitor, insectifuge, antiarthritic, anti-coronary, cardiovascular, anti-breast cancer, aromatic, and insectifuge. On the basis of the above investigation, the fruits can be recommended as a treasure of bioactive compounds and it plays a promising role in herbal medicine.Conclusion: The present study reveals that fruits of Z. rhetsa contain various bioactive compounds. Digitoxin is recorded in the ripened fruit of Z. rhetsa and it shows the anticancerous and cardiac arrest properties. Hence, in future, this plant will play a promising role in curing cancer.
