prangos ferulacea (l.) lindl. (apiaceae) is a medicinal plant distributed in mediterranean regions, caucasia and southwest of asia. in the present study phytochemical constituents of the extract obtained from the aerial parts of p. ferulacea were investigated using various chromatographic and spectroscopic methods. essential oil of the plant aerial parts was also analyzed using gc-ms. five phen...
This paper presents our distributed approach to dynamically assign new goals to a fleet of Unmanned Aerial Vehicles (UAVs). Decisions to assign new goals are not instantaneous and they tend to become obsolete because UAVs move continuously. We use the date of commitment to handle this. This paper introduces how we use a function relating the arrival date to the date of commitment in order to po...
The medicinal use of plants is probably as old as human kind itself. The World Health Organization (WHO) estimates that up to 80% of the world’s population relies on traditional medicinal system for some aspect of primary health care (Farnsworth et al., 1985) and the traditional medicines are generally more acceptable from a cultural and spiritual perspective. Many of the plants species used fo...
Invasion by alien species is a worldwide phenomenon with negative consequences at both natural and production areas. Acacia longifolia is an invasive shrub/small tree well known for its negative ecological impacts in several places around the world. The recent introduction of a biocontrol agent (Trichilogaster acaciaelongifoliae), an Australian bud-galling wasp which decreases flowering of A. l...
Continued interest in the chemistry of Dalea spp. led to investigation of Dalea searlsiae, a plant native to areas of the western United States. Methanol extractions of D. searlsiae roots and subsequent chromatographic fractionation afforded the new prenylated and geranylated flavanones malheurans A-D (1-4) and known flavanones (5 and 6). Known rotenoids (7 and 8) and isoflavones (9 and 10) wer...
Grewia optiva, a plant of northern area of Pakistan was screened for the natural products, antimicrobial and insecticidal activities. Phytochemical screening, using conventional natural products identification tests indicated the presence of different phytoconstituents. The ethyl acetate and methanolic extracts of the aerial parts of the tile plant revealed the presence of tannins, while terpen...
With the commercialization and increasing availability of Unmanned Aerial Vehicles (UAVs) multiple rotor copters have expanded rapidly in plant phenotyping studies with their ability to provide clear, high resolution images. As such, the traditional bottleneck of plant phenotyping has shifted from data collection to data processing. Fortunately, the necessarily controlled and repetitive design ...
Background and Purpose: Varthemia persica is an aromatic plant belonging to the Astraceae family. The plant is endemic to Iran. It contains volatile oils and the main constituents of volatile oils are sesquiterepens. There is no information regarding flavonoid constituents. Materials and Methods: Extract was prepared from freeze-dried power of flower, fruit and aerial parts with methanol-w...
BACKGROUND In order to find new bioactive natural products, the antimicrobial and antioxidant activities of essential oil components extracted from the separated organs of the Algerian medicinal and aromatic plant Daucus muricatus L. were studied. RESULTS The chemical composition of essential oils obtained by hydrodistillation (HD) was investigated using Gas Chromatography-Retention Indices (...
