We compared near-infrared (NIR) partial least squares models of a compact and a benchtop spectrometer to measure six nutritional traits of Brachiaria forages, including in-vitro dry matter digestibility (IVDMD), crude protein (CP), crude fiber (CF), acid detergent fiber (ADF), neutral detergent fiber (NDF), and lignin (LG). The relative prediction errors (RMSE/mean) for both instruments varied between 1.5% (for NDF) and 13% (for CP). Additionally, we obtained multivariate figures of merit and used a robust randomization t-test to comprehensively compare the two instruments. Our results show that, despite its lower analytical sensitivity, the compact instrument performs sufficiently well compared to the benchtop instrument and can be used for routine measurement of all six forage nutritional traits. The small performance difference between the two spectrometers can primarily be attributed to the narrower spectral range measured by the compact instrument. |

In the present study, a quassinoid, neosergeolide, isolated from the roots and stems of Picrolemma sprucei (Simaroubaceae), the indole alkaloids ellipticine and aspidocarpine, isolated from the bark of Aspidosperma vargasii and A. desmanthum (Apocynaceae), respectively, and 4-nerolidylcatechol, isolated from the roots of Pothomorphe peltata (Piperaceae), all presented significant in vitro inhibition (more active than quinine and chloroquine) of the multi-drug resistant K1 strain of Plasmodium falciparum. Neosergeolide presented activity in the nanomolar range. This is the first report on the antimalarial activity of these known, natural compounds. This is also the first report on the isolation of aspidocarpine from A. desmanthum. These compounds are good candidates for pre-clinical tests as novel lead structures with the aim of finding new antimalarial prototypes and lend support to the traditional use of the plants from which these compounds are derived. |
