قسمت اعظم مراتع کشور در مناطق خشک و نیمه خشک قرار دارد که در این اقلیم، نوسان بارندگی از عوامل عمدهای است که پوشش گیاهی و به دنبال آن تولید علوفه را تحت تأثیر قرار میدهد. در سالهای خشک که بارندگی کاهش مییابد، سطح پوشش گیاهی و میزان تولید علوفه آسیب میبیند. این تحقیق با هدف بررسی تغییرات پوشش گیاهی با بارندگی در مراتع نیمه استپی اردبیل در طی نه سال متوالی (1377تا 1385) انجام گردید. ن...
این تحقیق با هدف امکان سنجی استفاده از آمار مکانی در بررسی تغییرات مکانی و تهیه نقشه تراکم، پوششتاجی و تولید گونه Artemisia fragrans Willd. در مراتع جنوبشرقی سبلان انجام شد. ابتدا نرمالسازی دادهها با استفاده از نرمافزار SPSS16 انجام و سپس تجزیه و تحلیلهای آمار مکانی شامل بررسی ساختار مکانی پارامترهای تراکم، پوششتاجی و تولید گونه مورد مطالعه با ترسیم واریوگرام دادهها و تهیه نقشه پارامتر...
We report the chemical composition and anti-Leishmania and antioxidant activity of Artemisia campestris L. and Artemisia herba-alba Asso. essential oils (EOs). Our results showed that these extracts exhibit different antioxidant activities according to the used assay. The radical scavenging effects determined by DPPH assay were of IC50 = 3.3 mg/mL and IC50 = 9.1 mg/mL for Artemisia campestris a...
Artemisia argyi leaf is a widely used traditional Chinese medicine (TCM). In this work, for the first time, the separation and identification of volatile constituents in Artemisia argyi flowers is performed. Gas chromatography-mass spectrometry (GC-MS) with solid-phase microextraction (SPME) is developed for the fast analysis of volatile constituents in the flowers. Several headspace SPME param...
Artemisia capillaris, which belongs to the Asteraceae family and the genus Artemisia, has been reported to exert inhibitory effects on diabetes, cancer and inflammation. In this study, in order to enhance the bioactivity potential of the leaves of Artemisia by Ganoderma lucidum mycelium, we prepared aqueous samples of Artemisia capillaris (Ac) leaves, Ganoderma lucidum (Gl) and aqueous fraction...
Taxadiene is the first committed precursor to paclitaxel, marketed as Taxol, arguably the most important anticancer agent against ovarian and breast cancer. In Taxus, taxadiene is directly synthesized from geranylgeranyl diphosphate (GGPP) that is the common precursor for diterpenoids and is found in most plants and microbes. In this study, Artemisia annua L., a Chinese medicinal herb that grow...
The use of plant extract in the biosynthesis of nanoparticles (NPs) can be an eco-friendly approach and have been suggested as a possible alternative to classic methods namely physical and chemical procedures. This study was designed to examine the structural chemistry of silver nanoparticles (AgNPs) using both conventional heating and microwave irradiation methods.To o...
Submit Manuscript | http://medcraveonline.com could be evidenced for these drugs. Willcox is right in stating that no large scale, randomized, double blind clinical trials confirming the efficiency of Artemisia plants against malaria are available. Indeed, they are forbidden by WHO. Only clinical trials with ACTs have been run in high numbers. OXFAM and others even claim that Africans are guine...
A. annua is so named because it is almost the only member of the genus with an annual cycle. It is a shrub, often growing over 2 m high (Ferreira et al., 1997; see Figure 3.1 and Figure 3.2). Its leaves and flowers contain artemisinin, first isolated in China in 1971; this is the constituent with the greatest antimalarial activity (see Table 3.3). Artemisinin has been found in only two other sp...
