This allows accurate timely delivery health/medical information among patients, workers through widespread deployment wireless sensor networks mobile...

Abstract: Carbazole derivatives possess tricyclic structure consisting of two benzene rings fused on both sides with the central pyrrole ring. These compounds diversely appear in natural and synthetic sources. Carbazole-based have a wide range bioactivities such as antimicrobial, anticancer, antiparasitic, antihypertensive, antineuropathic, anti-inflammatory activities. Some carbazole been employed drugs market. The synthesis has attracted intensive interest from chemists huge number studies...

Abstract: An efficient and green method for the A3- coupling reaction of saliciladehyde, secondary amines, terminal alkynes to synthesize propargylamines using a microwave reactor has been demonstrated. The synthesis showed several salient features, such as high yield products, rapid product formation, environmentally benign conditions. Furthermore, could be performed in gram scale. Nine propargylamine adducts were obtained yields their structures confirmed by NMR data. A plausible mechanism...

Hedychium coronarium, commonly known as white ginger lily (Zingiberaceae), is a native species in Asian forests. The plant has long been used traditional medicine for treating pain and inflammatory conditions food-flavouring spice. In this work, the essential oil samples prepared from coronarium leaves, rhizomes, stems were analyzed by gas chromatography coupled with mass spectrometry (GC/MS) method, which gave information on main chemical components of leaf [β-pinene (27.90%), caryophyllene...

This case study was done to determine the impact of seasonal climate variability on rice production in Nam Dong District, Central Highland Vietnam. The Ordinary Least Square method applied establish relationships between climatic factors and yields two different growing seasons. are average maximum temperature (avemaxT), minimum (aveminT) rainfall (averain). seasons known as Winter-Spring (WS) Summer-Autumn (SA) season. data yield during these were collected from District Meteorological...

Rice straw is an important low-cost feedstock for bio-based economy. This report presents a study in which rice was used both as source isolation of bacteria producing the biodegradable polyester polyhydroxyalkanoate (PHA), well carbon production polymer by isolated bacteria. Of 100 bacterial isolates, seven were found to be positive PHA Nile blue staining and identified Bacillus species 16S rRNA gene sequence analysis. Three isolates showed 100% identity B. cereus, one paranthracis, two...

Abstract Essential oil obtained from hydrodistillation of the Vietnamese Syzygium boisanum leaves was analyzed by GC/FID‐MS (gas chromatography/flame ionization detection‐mass spectrometry). Forty‐five compounds (90.08%) were namely identified, in which sesquiterpene hydrocarbons (73.07%) major chemical class. Among identified compounds, β ‐caryophyllene (18.21%) and bicyclogermacrene (25.47%) principal compounds. This essential comparable with positive control streptomycin an antimicrobial...

The chemical constituents, antimicrobial and larvicidal activities of essential oils obtained by hydrodistillation the leaves Magnolia coco (Lour.)DC. are being reported.The were analyzed using Gas Chromatography-Flame Ionization Detector (GC-FID) Chromatography-Mass Spectrometry (GC-MS) while activity was evaluated protocol World Health Organization (WHO).The microbroth dilution assay used for study activity.The major compounds in oil sabinene (35.4%) β-pinene (16.3%).The exhibited 100%...

Syzygium plants are known as sources of biologically active substances. The essential oils constituents and antimicrobial activity petelotii Merr. & Perry syzygioides (Miq.) from Vietnam being reported. Essential were obtained by hydrodistillation the leaves S. collected Pù Hoạt Nature Reserve, Vietnam. determined using gas chromatography (GC) chromatography-mass (GC/MS) spectrometry methods. was evaluated microdilution broth susceptibility assay. results indicate that γ-guaiene (24.1%),...

Abstract: Imidazole derivatives, which belong to 1,3-diazole family, have two nitrogen atoms at 1 and 3 positions in the aromatic ring. derivatives diversely appear both nature synthetic sources. Some natural imidazoles play important roles human life such as histidine, histamine biotin. Imidazole-based compounds possess a wide range of bioactivities those including antimicrobial, anticancer, antiparasitic, antihypertensive, antineuropathic anti-inflammatory activities. Many with imidazole...

AbstractHedychium yunnanense Gagnep., belonging to the Zingiberaceae family, has aroused much interest due its non-volatile chemical constituents. Nevertheless, no data about essential oils (EOs) of this species is available. In study, composition and antimicrobial activity EOs from leaves rhizomes H. collected in Vietnam were analyzed. The obtained as yellow with extraction yields 0.21 0.09%, respectively. Fifty-seven components, accounting for 94.35-98.92%, identified two EOs. EO mainly...

Oxazole-containing compounds have diverse biological activities, such as antimicrobial, anticancer, antitubercular, anti­inflammatory, antidiabetic, antiobesity, antimalarial, and antiviral some of them been used drugs for treating diseases. They also play important roles in the synthesis bioactive natural products, pharmaceuticals synthetic transformations well materials, catalyst agriculture fields. Thus, development more efficient facile approaches to access oxazole has attracted...

Abstract: A facile and green strategy for the Knoevenagel condensation reaction of aryl aldehydes active methylene compounds using [Bmim][CF3COO] ionic liquid as a solvent catalyst has been introduced. The method features some advantages such good to excellent yield products, relatively short time, mild conditions, broad substrate scope, scalability. Moreover, could be conveniently recycled reused up three times without any considerable loss catalytic activity. Twelve products were obtained...

Abstract: An efficient and environmentally-friendly protocol for the synthesis of 2- (arylamino) thiazoles has been investigated. The two-step, three-component reaction aryl ketones, Nbromosuccinimide, thiourea derivatives was performed using [bmim][BF4] ionic liquid as a solvent in one pot gave products good to excellent yields. Furthermore, could be reused up 5th time without considerable decrease yield. Thirteen were obtained high yields (78-89%) under mild conditions (ambient temperature...
