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...

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...

The aim of this study was to investigate the Stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. The volatile constituents from the aerial parts of Stachys turcomanica growing wild in Iran were obtained by hydrodistillation and analyzed by GC and GC-MS. In the GC-MS analysis, Forty-six components representing 81.1% of the oil were identifie...

This paper studies mathematical properties of h-index sequences as developed by Liang [Liang, L. (2006). h-Index sequence and h-index matrix: Constructions and applications. Scientometrics, 69(1), 153–159]. For practical reasons, Liming studies such sequences where the time goes backwards while it is more logical to use the time going forward (real career periods). Both type of h-index sequence...

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...

Herbs have long been used in the treatment of various disorders in traditional medicine since ancient age. Artemisia absinthium, one of these herbs, has traditionally been used in different societies for antibiotic, antiparasitic, antifungal and antipyretic purposes. Here, we report a poisoning case of a 10-month-old male infant progressing with severe diarrhoea and persistent metabolic acidosi...

The first study of the aphid fauna from Chukotka Autonomous Okrug has been made; 18 species are reported from this territory, the most north-eastern of Russia and of the Palaeartic Region. Five new species are described: Aphis aquilonalis sp. nov. on Rumex arcticus Trautv.; Aphis beringiensis sp. nov. were collected by yellow trap; Macrosiphoniella (Asterobium) jaroslavi sp. nov. on Artemisia a...

This study aimed to determine phenolic compounds of Artemisia spicigera (family Asteraceae) growing in East-Azarbaijan province of Iran. 20%, 40 % and 60% SPE fractions of methanolic extract of A. spicigera, were subjected to reversed phase preparative HPLC, with the mobile phase consisted of methanol and water. Structural identification of phytochemicals by spectroscopic methods including UV a...
