The unripe fruit of Meyna spinosa / Laxiflora is used for the treatment of diabetes by traditional healers. The effect of the aqueous extract of the fruit is investigated on the normal and elevated blood glucose level of the experimental animal rats. The blood glucose level of the rats is elevated with the administration of I.P streptozotocin. The estimation of the blood glucose level is done by using a kit based on the glucose oxidase method. The rat has a blood glucose level above 280mg/dl is considered for the normal and anti-hyperglycemic study. The doses of the extract are selected as 200, 300mg/kg, and the route of administration is oral. The effect of the extract on the normal and elevated glucose level of the rat is compared with that of the standard drugs- glibenclamide and metformin. The effect of the extract on normal blood glucose level is not significant when compared with that of glibenclamide, whereas the effect of the extract on elevated blood glucose level is significant when...

Background and Objectives: Cyanobacteria are rich in various bioactive compounds. This study aims to screen the antimicrobial activity of sub-aerial Cyanobacteria isolated from sub-aerial habitats (Old monuments and building facades). Materials and Methods: Crude aqueous and organic extracts were screened for phytochemical constituents and tested for their antimicrobial efficacy against human pathogens. The crude extract that showed better antimicrobial activities were further fractionated by column chromatography and purified by TLC. The active bands were scraped out separately and concentrated in vacuo to isolate pure compounds. Each purified compounds dissolved in respective solvents, assayed for antimicrobial activities were further characterised through FTIR and LC-MS. Results: The results indicated the presence of many secondary metabolites. Of the isolated purified compounds, the compounds from three species, viz. Scytonema hyalinum, Tolypothrix rechingeri, and Fischerella species exhibited antimicrobial activities, whereas others showed antibacterial activity. The FTIR spectra revealed the peaks of carboxylic acid, alkaloids, and phenolic compounds. The chemical compounds were identified as 1,3-dihydroxycyclohexane [Lyngbya kuetzingiana], 4-(4-hydroxyphenyl) butanoic acid [Nostoc linckia], octahydro-1H-indole-2-carboxylic acid [Scytonema...

Linalool is the first ingredient to synthesize many other substances of higher value for the pharmaceutical and fragrance industry; therefore, finding sources of essential oils containing Linalool is an important and necessary task. The purpose of this study is to investigate Linalool of plants containing essential oil in Vietnam to extract Linalool sources for the pharmaceutical and fragrance industry. By the method of fresh sampling of essential oil plants in Vietnam, essential oils are extracted by steam distillation and then analyze on high-resolution chromatography (HRGC) to search for Linalool sources. We have found that some areas with a lot of plants containing high Linalool content grow concentrated wild in forests as Coriandrum sativum Linn., Homalomena occulta (Lour.) Schoot, Cinnamomum parthenoxylon Meissn, and some of them can be planned to cultivate the essential oil source to obtain Linalool for the pharmaceutical and aromatic industry. During the survey, we discovered and made a list of 21 plants with essential oil containing Linalool in...

The present study aimed to explore the primary metabolites present in leaf, fruit, and seed crude extracts of Syzygium cumini L by Gas chromatography – Mass spectrometry. The compounds in the leaf, seed, and fruit extracts resulted from the GC-MS analysis was relevant to the National Institute of Standards and Technology (NIST) library. The metabolite profiling of the extracts revealed the presence of carboxylic acid and fatty acid found to be common in leaf, fruit, and seed extracts. And metabolites 6-oxa-3-thiaoctanoic acid, bisoprolol, phenacetin, tropin, alizarin, gonodoic acid are present in seeds that are not found in leaves and fruit metabolite profile. In contrast, Tetra decanoic acid, Azelaic acid, Penicillamine and S (-)-Cathinone are found only in leaves. Leaf, fruit and seed extracts of Syzyzium cumini L contains various bioactive compounds and consequently has a variety of medicinal properties for the treatment of different diseases like thyroid cancer, heart diseases, kidney stones and rheumatoid arthritis. Some metabolites found to be active as antidiabetic, anti-inflammatory, anti-cancerous, antioxidant, anti-bacterial and antifungal...

Azadirachta Indica has always been known to be the bestowed with good health for many centuries in India. It has been found that the Neem is native to Asian countries. There are three major active components in A. indica, namely nimbin, nimbidin, and nimbiene. The compound nimbidin was isolated by chromatographic techniques. A. indica leaves extract was prepared, and the phytochemical analysis was conducted, and the phytochemical screening manifested the presence of alkaloids, flavonoids, reducing sugar, phenol, saponins and cardiac glycoside in the neem extract. Then qualitative phytochemical analysis was conducted for flavonoids, alkaloids, saponins, and phenol. Plant sources are considered the major active source of antioxidant molecules for a long time in the history of humankind. In the current study, the anti-bacterial properties of Neem have been tested against gram-positive bacteria, namely, Staphylococcus aureus, Bacillus subtilis, and gram-negative bacteria, namely, Escherichia coli Pseudomonas aeruginosa, Klebsiella pneumoniae, and proteus vulgaris. Chloramphenicol was used as a standard to analyze the effect of the nimbidin compound. The compounds obtained from plants...
