Determination of Cassiarin A Level of Cassia siamea Leaf ...

Cassia siamea leaf has been proven in vitro and in vivo to have a strong antimalarial activity with Cassiarin A as its active compound. To obtain a source of C. siamea medicinal plant with high level of active antimalarial compound (Cassiarin A), a valid method for determining Cassiarin A level is needed. For this reason, this research conducts the validation of the Cassiarin A content with ...

Precision was expressed in terms of repeatability, based on calculation of the estimate of the relative standard deviation (,RSD,). Samples of river (Carmo River) and mine ,water, (mine D) were spiked with 1, 3 and 10 µg L-1 of As(III) and As(V) (n = 3), in which the obtained ,RSD, was less than 8% for the different arsenic concentrations.

The calibration graph was linear for 9-100 µg/l of nitrite, with a detection limit of 3.5 µg/l. Large quantities of chloride were removed by precipitation with Ag(I). The method was applied to the analysis of river ,water,, well ,water, and waste ,water,, with recoveries of 94-108% and ,RSD, of 0.81-1%. The sampling frequency was 65 runs per h.
