Bioactive Labdane Diterpenoids from Renealmia alpinia Collected in the Suriname Rainforest

Journal of Natural Products, 1997
The preservation of tropical rainforests is an important goal both for the intrinsic value of their cultural and biological diversity as well as for the well-being of the peoples who make these forests their home. In addition, tropical forests are potential sources of new pharmaceutical products that can only be found by chemical prospecting in Nature ...

On the characterization of some terpenes from Renealmia alpinia rott. (maas) oleoresin

Flavour and Fragrance Journal, 1991
AbstractRenealmia alpinia Rott. (Maas) (Zingiberaceae) seeds contain 14% of a dark brown oleoresin which was investigated by a combination of chromatographic and spectrometric techniques. The volatiles (4.4% of the oleoresin) extracted from the oil by hydro‐distillation were mainly monoterpene hydrocarbons (β‐pinene 22.3%, limonene 18.4% and β ...

Inhibitory effect of pinostrobin from Renealmia alpinia, on the enzymatic and biological activities of a PLA2

International Journal of Biological Macromolecules, 2016
Pinostrobin is a flavanone isolated from Renealmia alpinia, a plant used in folk medicine to treat snakebites. We tested the inhibitory ability of pinostrobin on the enzymatic, anticoagulant, myotoxic and edema-inducing activities of a PLA2 isolated from Crotalus durissus cumanensis venom.

Vertebrate Fruit Removal and Ant Seed Dispersal in the Neotropical Ginger Renealmia alpinia (Zingiberaceae)*

Biotropica, 2009
ABSTRACTPlants frequently display fruit characteristics that support multiple seed‐dispersal syndromes. These ambiguous characteristics may reflect the fact that seed dispersal is usually a complex process involving multiple dispersers. This is the case for the Neotropical ginger Renealmia alpinia (Zingiberaceae).

Inhibition of the toxic effects of Bothrops asper venom by pinostrobin, a flavanone isolated from Renealmia alpinia (Rottb.) MAAS

Journal of Ethnopharmacology, 2014
Renealmia alpinia has been traditionally used to treat snakebites by indigenous Embera-Katíos tribes belonging to the regions of Antioquia and Chocó, Colombia, and it has been shown to inhibit the enzymatic and biological activities of Bothrops venoms and their purified phospholipase A2 (PLA2) toxins.

Inhibition of venom serine proteinase and metalloproteinase activities by Renealmia alpinia (Zingiberaceae) extracts: Comparison of wild and in vitro propagated plants

Journal of Ethnopharmacology, 2013
The plant Renealmia alpinia has been used in folk medicine to treat snakebites in the northwest region of Colombia. In addition, it has been shown to neutralize edema-forming, hemorrhagic, lethal, and defibrin(ogen)ating activities of Bothrops asper venom.

A New Labdane Diterpenoid from Renealmia alpinia Collected in the Suriname Rainforest

Journal of Natural Products, 1999
Continuation of a previous study on Renealmia alpinia resulted in the isolation of the new labdane diterpenoid 3, together with two known diterpenoids. The structure of the new diterpenoid was determined by a combination of NMR techniques and HRFABMS.
