Physiological and biochemical characterization of the assai palm (euterpe olera...

Primary metabolite mobilization during germination in rosewood (Aniba rosaeodor...

This study aimed to characterize protein, oil, starch and soluble sugar mobilization as well as the activity of α-amylase during rosewood seed germination. Germination test was carried out at 25°C and the following parameters were analyzed: percentage of germination, initial, average, and final germination time. Seed reserve quantification was monitored in quiescent seeds and during different stages of radicle ...

Plants of the araceae family for malaria and related diseases: A review

In the current work we performed a review of the Araceae family species traditionally used to treat malaria and its symptoms. The aim is to reveal the large number of antimalarial Araceae species used worldwide and their great unexplored potential as sources of antimalarial natural products. The SciFinder Scholar, Scielo, PubMed, ScienceDirect and Google books search engines were consulted. Forty-three records ...

In vitro and in vivo anti-malarial activity of plants from the Brazilian Amazon

Background: The anti-malarials quinine and artemisinin were isolated from traditionally used plants (Cinchona spp. and Artemisia annua, respectively). The synthetic quinoline anti-malarials (e.g. chloroquine) and semi-synthetic artemisinin derivatives (e.g. artesunate) were developed based on these natural products. Malaria is endemic to the Amazon region where Plasmodium falciparum and Plasmodium vivax drug-re...

Amazonian plant natural products: Perspectives for discovery of new antimalaria...

Plasmodium falciparum and P. vivax malaria parasites are now resistant, or showing signs of resistance, to most drugs used in therapy. Novel chemical entities that exhibit new mechanisms of antiplasmodial action are needed. New antimalarials that block transmission of Plasmodium spp. from humans to Anopheles mosquito vectors are key to malaria eradication efforts. Although P. vivax causes a considerable number ...

Plants of the annonaceae traditionally used as antimalarials: A review

Species of the Annonaceae family are used all over the tropics in traditional medicine in tropical regions for the treatment of malaria and other illnesses. Phytochemical studies of this family have revealed chemical components which could offer new alternatives for the treatment and control of malaria. Searches in scientific reference sites (SciFinder Scholar, Scielo, PubMed, ScienceDirect and ISI Web of Scien...

Physiological and biochemical characterization of the assai palm (Euterpe olera...

Physiological and biochemical aspects of assai palm during seed germination and early seedling growth were investigated. Seeds collected from plants growing in flooded and upland forests were used to determine the influence of normoxic (aerobic) and anoxic (anaerobic) conditions in germination and the initial and average time of development in the roots and shoots. After 75 days, seedlings germinated under norm...

Physiological and biochemical characterization of the assai palm (Euterpe olera...

Aspectos fisiológicos e bioquímicos durante a germinação de sementes e crescimento inicial de plântulas de açaí foram investigados. Sementes coletadas de plantas crescendo na várzea e na terra firme foram utilizadas para determinar a influência das condições de normoxia (aeróbica) e de anoxia (anaeróbica) na germinação e no tempo inicial e médio do desenvolvimento da raiz e parte aérea. Após 75 dias, plantas ge...
