Cytotoxic Diterpenoids from Isodon megathyrsus
Journal of Natural Products, 1994A new diterpenoid, megathyrin A, together with three known compounds, rabdocoetsins B, C, and D, were isolated from the leaves of Isodon megathyrsus, and their structures and nmr spectral data were assigned by a combination of one- and two-dimensional nmr techniques. These compounds displayed significant cytotoxic activity.

Development of Megathyrsus Maximus Genotypes for Intensification of Cattle Rearing in Brazil
XXV International Grassland Congress (IGC 2023), 2023Megathyrsus maximus is a forage species used over 30 million hectares in Brazil and in the surrounding countries for intensification of the cattle production systems. Due to the large area and distinct biomes in which it is used, there is a need to continuously develop more productive and adapted cultivars to each biome and use.

Megathyrin B: A Cytotoxic Diterpene fromIsodon megathyrsus
Planta Medica, 1998From the leaves of Isodon megathyrsus, a novel ent-kaurene diterpene, megathyrin B, was isolated and its structure determined as 1 alpha,7 beta,11 beta,15 beta-tetrahydroxy-ent-7 alpha,20-epoxy-kaur-16-ene by 1D- and 2D-NMR spectral analysis. Additionally, its stereochemistry was unambiguously assigned by X-ray crystallography.

Effects of leaf and stem maturation on nutritional value in Megathyrsus maximus
Journal of the Science of Food and AgricultureAbstractBackgroundMegathyrsus maximus is a forage grass native to Africa but widely cultivated in tropical and subtropical regions of the world where it is part of the grazing food chain. This study aimed to evaluate five M. maximus genotypes for the effect of maturity on their morpho‐agronomic traits, nutritional composition and digestibility, and to ...

Growth, productivity and quality of Megathyrsus maximus under cover from Gliricidia sepium
Agroforestry Systems, 2013The effect of tree canopy on the growth, productivity and forage quality of Megathyrsus maximus and changes in soil properties were evaluated over three seasonal periods. Four adjacent plots (15 m × 17 m each) in a tropical secondary deciduous forest having 12 years of growth and dominated by Gliricidia sepium were randomly assigned to two treatments ...
