The chemical composition of the essential oil of Etlingera yunnanensis rhizomes and its contact and repellent activities against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel) were investigated. The essential oil obtained from E. yunnanensis rhizomes with hydrodistillation was performed by gas chromatography-flame ionization detection and gas chromatography-mass spectrome...

BACKGROUND Alpinia murdochii (Zingiberaceae) is a wild ginger species restricted to mountain areas of Peninsular Malaysia. Due to rapid development and deforestation activities, this species is becoming rare. This is the first report of the cytotoxic activity of A. murdochii. OBJECTIVE The present study aimed to investigate the cytotoxic effect of leaves and rhizomes of A. murdochii against s...

The aim of this research was to determine the chemical composition and insecticidal activity of the essential oil of Curcuma wenyujin Y.H. Chen et C. Ling rhizomes against the booklouse Liposcelis bostrychophila Badonnel and to isolate any insecticidal constituents from the essential oil. The essential oil of C. wenyujin rhizomes was obtained by hydrodistillation and analyzed by GC-MS. A total ...

The different extracts of Hedychium spicatum Buch.-Ham. (Zingiberaceae) were evaluated for antioxidant activity by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and reducing power determination method. Total phenol and total flavonoid content in each extracts were also determined. Gallic acid and ascorbic acid were used as reference standards. They exhibited strong antioxida...

This study investigates the impact of wastewater irrigation on soil–plant–water system at vegetative, flowering, and reproductive stages Phragmites australis for two four days (in each stage) in coastal saline area Urmia Lake. The concentrations potentially toxic elements were detected irrigated water, soil, plant (aboveground belowground) tissues, transfer factor bioaccumulation calculated. sh...

Inhibition of vascular smooth muscle cell (VSMC) proliferation is of substantial interest in combating cardiovascular disease. A dichloromethane extract from the rhizomes of Peucedanum ostruthium, a traditionally used Austrian medicinal plant with anti-inflammatory properties, was examined for a putative antiproliferative activity in rat aortic VSMC. This extract inhibited serum (10%)-induced V...

turmeric (curcuma longa l.) is extensively used as a spice, food preservative and colouring material. it has been used in traditional medicine for various diseases. curcumin, the main yellow bioactive component of turmeric has been shown to have a wide spectrum of biological actions. heretofore, it has been reported that natural colored extracts isolated from turmeric rhizomes with many methods...

Bioactive compound from essential oils of Alpinia malaccensis (AM) and Kaempferia galanga (KG) rhizomes, respectively, such as methyl cinnamate ethyl-p-methoxycinnamate (EPMS) have been reported to anti-inflammatory activity. The present study aimed determine the topical activity 3 gel formulations (Formula 1, 2 3) having different concentrations oil AM KG rhizomes. gelling agent used in this w...

Fertilisation has a significant impact not only on the yielding, but also quality of harvested biomass. Among energy crops, Miscanthus × giganteus are some most important plants used for combustion process. The chemical composition biomass effect nitrogen fertilisation (with dose 60 kg N ha?1) in different terms sampling content and uptake crude ash, potassium, calcium sulphur by rhizomes, stem...

Rhizomes of Sinopodophyllum hexandrum and Dysosma species, which have long been used in the traditional Chinese herbal medicine, have similar morphology and chemical composition. However, the podophyllotoxin content is higher in the rhizomes of S. hexandrum than in those of Dysosma species. The PCR-amplified fragments of trnT -trnL showed length variation between S. hexandrum and Dysosma specie...
