artemisia deserti krasch (a. deserti), artemisia aucheri (a. aucheri) and artemisia sieberi besser (a. sieberi) are three members of asteraceae (compositae) family, which grow widely in the even and high areas of birjand, iran. this study has attempted to compare the total antioxidant capacity of methanol extracts of these three plants using dpph (1,1-diphenyl-2-picrylhydrazyl) radical scavengi...
Background and Objective: For most of cancers there is no treatment and most of them ended in death. So, the first investigational stage is evaluation of toxic effects of drug fractions on cancer cells. Artemisia species are important medicinal plants throughout the world. In this study, anti-tumoral effects of seven Artemisia spp. fractions from Iran were studied on cancer and normal cells. Ma...
Background: Breast cancer is one of the most common cancers among women. Chemotherapy drugs such as taxol often lead to toxicity. Artemisia from Asteraceae family, contain flavonoids such as Artemisin which is one of the most important medicinal plants in the world. Therefore, in the present study the cytotoxic and apoptotic effects of two ethanol extract (Artemisia scoparia, Artemisia siberia)...
Shoot cultures of Artemisia annua L. were cultivated in three different micropropagation systems: an ultrasonic nutrient mist bioreactor (UNMB), a modified ultrasonic nutrient mist bioreactor (MUNMB) and solid culture in Magenta boxes. The shoots cultivated in the UNMB and MUNMB showed excellent growth. The dry weight increase (35 times) of shoot cultures in the MUNMB was higher than those (25 ...
In order to determine the effect of climatic factors on distribution of Artemisia aucheri and Artemisia sieberi in Isfahan province, thirty nine most important climatic elements in ecological condition of these species were selected. Using a factor analysis method, the most important factors in distribution of these species were determined. These factors which cover 92.3% of the total variance ...
Artemisia indica, also known as "Mugwort," has been widely used in traditional medicines. However, few studies have investigated the effects of nonvolatile components of Artemisia indica on central nervous system's function. Fractionation of Artemisia indica led to the isolation of carnosol, ursolic acid, and oleanolic acid which were evaluated for their effects on GABA-A receptors in electroph...
BACKGROUND & OBJECTIVES Artemisinin isolated from Artemisia annua is the most potent antimalarial drug against chloroquine-resistant Plasmodium falciparum malaria. Artemisia vulgaris, an invasive weed, is the only Artemisia species available in Sri Lanka. A pilot study was undertaken to investigate the antiparasitic activity of an A. vulgaris ethanolic leaf extract (AVELE) in a P. berghei ANKA ...
Plants synthesize a great variety of isoprenoid products that are required not only for normal growth and development but also for their adaptive responses to environmental challenges. However, despite the remarkable diversity in the structure and function of plant isoprenoids, they all originate from a single metabolic precursor, mevalonic acid. The synthesis of mevalonic acid is catalysed by ...
Sagebrush (Artemisia spp.) communities constitute the largest temperate semidesert in North America and provide important rangelands for livestock and habitat for wildlife. Remote sensing methods might provide an efficient method to monitor sagebrush communities. This study used airborne LiDAR and field data to measure vegetation heights in five different community types at the Reynolds Creek E...
