Rhizobacteria isolated from wild dipterocarp saplings in Central Kalimantan, Indonesia, were subjected to Salkowski’s reagent test, which is often used detecting indolic substances. Among 69 isolates grown a low-nitrogen medium supplemented with l-tryptophan (TRP), culture fluids of 29 strains positive the 17 bacteria turned red and other 10 pink. All type rhizobacteria actively converted TRP into tryptophol (TOL), while some yielded indole-3-acetic acid (IAA) TOL production. They also...
The aim of this study was to examine the chemical composition essential oil isolated from floral parts Magnolia liliflora Desr. by hydrodistillation, and test efficacy various leaf extracts against a diverse range microorganisms comprising food spoilage foodborne pathogenic bacteria. analyzed GC-MS. It determined that 52 compounds, which represented 78.07% total oil, were present in oil. contained mainly levoxine (15.59%), methylcyclopropane (24.26%), 2-beta-pinene (5.3%), caryophyllene...
A total of 30 bacteria were isolated from the rhizoplane rice cv. BR29 cultivated in Mymensingh, Bangladesh and seedlings obtained surface-sterilized seeds BR29. Upon screening, 6 isolates showed varying levels phosphate solubilizing activity both agar plate broth assays using National Botanical Research Institute’s medium. The bacterial identified based on their phenotypic 16S rRNA genes sequencing data as Acinetobacter sp. BR-12, Klebsiella BR-15, BR-25, Enterobacter BR-26, Microbacterium...
The antibacterial potential of essential oils and methanol extracts sweet basil Ocimum basilicum L. (Lamiaceae) was evaluated for controlling the growth range food-borne pathogenic bacteria. Essential extracted by hydrodistillation from leaves stems were analyzed GC-MS. Fifty-seven compounds representing 94.9 96.1% total leaf stem oils, respectively, identified, which methyl chavicol (36.7 29.9%), gitoxigenin (9.3 10.2%), trimethoquinol (10.3 8.4%), beta-guaiene (3.7 4.1%), aciphyllene (3.4...
We examined the anticancer effects of limonin and imperatorin on various human cancer cells by MTT assay, results showed that inhibited cell growth SNU 449 (liver cancer) HCT-15 (colon in a dose-dependent manner, while had less effect. Exposure different concentrations caused morphological changes cells, but not normal dermal fibroblast cells. Limonin induced apoptotic death concurrent to cycle arrest up regulated proapoptotic protein Bax expression down anti-apoptotic Bcl-2 manner In...
The aims of this study were to examine the chemical composition essential oil Premna integrifolia Linn (Lamiaceae), and test efficacy various organic extracts as an antibacterial potential. compositions analyzed by GC–MS. Twenty-nine compounds representing 94.81% total leaves identified, which phytol (27.25%), α-humulene (14.21%), spathulenol (12.12%), 1-octen-3-ol (8.21%), eugenol (6.69%) phenylethyl alcohol (5.81%) major compounds. (15 μL disk−1) (300 μg P. displayed a great potential...
This study was undertaken to assess the antifungal potential of essential oil and various extracts Mikania scandens (L.) Willd. The hydrodistilled leaf M. analysed by GC–MS. Twenty-four compounds representing 97.45% total leaves were identified, which β-caryophyllene (16.98%), δ-cadinene (12.22%), α-cubebene (11.33%), 1,2-benzenedicarboxylic acid (10.17%), caryophyllene oxide (7.74%), β-himachalene (4.68%), T-cadinol (3.98%), tetratetracontane (3.83%), 1H-cyclopropa[a]naphthalene (3.56%),...
Summary In this study, we examined the chemical compositions of essential oil and tested efficacy organic extracts Cestrum nocturnum L. against food‐borne pathogens. The was analysed by gas chromatography‐mass spectrometry (GC‐MS). Forty‐seven compounds representing 93.28% total were identified. [5 μL 1:5 (v/v) dilution with methanol] hexane, chloroform, ethyl acetate methanol (300 μg per disc) C. displayed a great potential antibacterial activity Staphylococcus aureus (ATCC 6538 KCTC 1916),...
Dried methanol extract of leaves Cassia sophera L. was dissolved in distilled water, and then fractioned by re-extracting with n-hexane, chloroform, ethyl acetate, subsequently. The free radical scavenging activity (FRSA) various fractions determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. FRSA acetate fraction superior to all other (IC50 = 15.42 g/ml), which higher than synthetic antioxidant butylated hydroxyanisole, BHA (18.25 µg/ml). amount total phenolic compounds further...
Abstract The efficacy of the essential oil and various leaf extracts Piper chaba Hunter was evaluated for controlling growth some important phytopathogenic fungi. hydrodistilled analysed by GC–MS. Fifty‐three compounds representing 95.1% total were identified, which α‐humulene (16.4 % ), caryophyllene oxide (12.2 viridiflorol (8.1%), globulol (7.4%), β‐selinene (7.1%), spathulenol (6.2%), ( E )‐nerolidol (5.1%), linalool (4.5%) 3‐pentanol (3.5%) major compounds. (1,000 ppm) organic (1,500 P....
In this study, we identified some Bacillus sp. from soil by16S rDNA sequence analysis and tested the efficacy of essential oil various organic extracts Cassia sophera L. against those isolated bacteria. We also determined chemical composition which was analyzed by GC–MS. Twenty-nine compounds representing 94.14% total identified. The zones inhibition bacteria were found in range 12.6–24.9 mm. Among all extracts, ethanol extract showed highest activity megaterium with an MIC value 62.5 μg/ml....
ABSTRACT This study aimed to evaluate the phenolics, antioxidant and tyrosinase inhibitory activities of ethanol extracts various parts Lonicera japonica Thumb. including flowers, leaves branches. The were found be highly enriched in total phenolic contents as gallic acid equivalents capacity L-ascorbic equivalents. exhibited potent 1,1- diphenyl-2-picrylhydrazyl (DPPH) superoxide radical-scavenging activities, which stronger than butylated hydroxyanisole slightly weaker ascorbic acids....
