Pharmacognostic Study, Diuretic Activity and Acute Oral Toxicity of the Leaves of Aubl. Collected in Two Different Phenological Stages.

Aubl. is traditionally used in Cuba as an analgesic, anti-inflammatory, antilithiatic and diuretic remedy. Here we studied the pharmacognostic parameters of the leaves of , the preliminary phytochemical composition, diuretic activity and acute oral toxicity of the aqueous extracts from the leaves of plants collected in the vegetative (VE) and flowering (FE) stages.

Phytochemical characterisation and antilithiatic activity of the stems of (Brasilete).

The aim of this work was to identify the main chemical constituents and to evaluate the antilithiatic activity of the aqueous and hydroalcoholic extracts of stems of Lam. Fractionation and isolation of constituents from the hydroalcoholic extract was carried out by flash chromatography and semi-preparative liquid chromatography. The antilithiatic activity of the aqueous and hydroalcoholic extracts was evaluated in Wistar rats, where kidney stones were induced by ethylene glycol and ammonium chloride.

In vitro antimalarial activity and cytotoxicity of some selected cuban medicinal plants.

Terrestrial plants have been demonstrated to be sources of antimalarial compounds. In Cuba, little is known about antimalarial potentials of plant species used as medicinals. For that reason, we evaluated the antimalarial activity of 14 plant species used in Cuba as antimalarial, antipyretic and/or antiparasitic.

[Antimalarial activity of hydroalcoholic extract from Bixa orellana L].

Introduction: Bixa orellana L. is one species used in traditional herb medicine in several continents. Among the medicinal properties attributed to this plant, the antimalarial action has been included.

[Antimalarial activity and cytotoxicity of hydroalcoholic extracts from six plant species used in Cuban traditional medicine].

Introduction: Malaria is the most important parasitic disease for global health. Lack of the structural diversity in current antimalarials demands the urgent search for new therapeutic alternatives. The plants have shown their potential to provide effective antimalarials, therefore, a large sample of Cuban medicinal plants is being studied.

In vitro anti-microbial activity of the Cuban medicinal plants Simarouba glauca DC, Melaleuca leucadendron L and Artemisia absinthium L.

In the present study, an extensive in vitro antimicrobial profiling was performed for three medicinal plants grown in Cuba, namely Simarouba glauca, Melaleuca leucadendron and Artemisia absinthium. Ethanol extracts were tested for their antiprotozoal potential against Trypanosoma b. brucei, Trypanosoma cruzi, Leishmania infantum and Plasmodium falciparum.

[Inhibiting activity of the in vitro growth of Plasmodium falciparum of extracts from algae of genus Laurencia].

Several terpenoids have been identified in the genus Laurencia showing antimalarial activity; however it is a genus of great chemical complexity worldwide. The majority of these substances have been extracted from collections made in Philippines and Brazil. In order to know the presence of antimalarial activity in organisms of this genus from the North West Coast of Cuba, we prepared extracts in ethanol with the whole plant of specimens of L.
