Gynocardin and cyclopentenylglycine in Rawsonia lucida.

Tetraphyllin B, volkenin and cyclopentenylglycine in Androsiphonia adenostegia.

Mode of origin and sources of genotypic diversity in triploid gynogenetic fish clones (Poeciliopsis: Poeciliidae).

Most tributaries of the Río Fuerte in northwestern Mexico contain one or more clones of allotriploid fish of the genus Poeciliopsis. We used multilocus allozyme genotypes and mitochondrial DNA (mtDNA) haplotypes to examine several potential modes of origin of these gynogenetic all-female fish. The allozyme studies corroborated earlier morphological work revealing the hybrid constitution of two ...

Morinda lucida reduces contractility of isolated uterine smooth muscle of pregnant and non-pregnant mice.

The present work investigated the effect of Morinda lucida (M. lucida) extract on isolated uterine smooth muscle of pregnant and non-pregnant mice. Pregnant and non-pregnant mice were pretreated with oral stilboesterol (0.1 mg/kg body weight) and killed by cervical dislocation. Thin strips of the uterus were cut and mounted in a 20 ml organ bath containing De Jalon solution bubbled with 95%O2-5...

Evaluation of Antimalarial Activity of Various Fractions of Morinda lucida Leaf Extract and Alstonia boonei Stem Bark

Investigation into antimalaria activity of various fractions of Morinda lucida leaf extract and Alstonia boonei stem bark was conducted using standard techniques. The present study confirms the antimalarial activity of Morinda lucida and Alstonia boonei. Morinda lucida exhibited MIC of 0.6mg/ml and Alstonia boonei MIC 0.2mg/ml. The anti plasmodia activity of both plants were found to reside maj...

Cognitive-enhancing Properties of Morinda Lucida (rubiaceae) and Peltophorum Pterocarpum (fabaceae) in Scopolamine-induced Amnesic Mice

BACKGROUND Cognitive disorders associated with aging have been successfully managed by African traditional medical practitioners using various plants. This study evaluated the cognitive enhancing potentials of Morinda lucida (L) Rubiaceae and Peltophorum pterocarpum (DC) ex. K Heyne in scopolamine induced amnesic animals. MATERIALS AND METHODS The anti-amnesic activity of the ethyl acetate ex...
