concentration plant methods

WO2016029998A1 Method for determining the concentration

In a method for determining the concentration of glucoraphanin in a plant, a sample of the plant is provided, the sample is brought into contact with a polar, uncharged organic solvent and comminuted in such a way that glucoraphanin contained in the sample and further plant substances contained in the sample are dissolved in the solvent and undissolved plant constituents are removed from the

A sensitive and quick microplate method to determine the

The method is quick, worked well with Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Escherichia coli and with non-aqueous extracts from many different plants. The method gave reproducible results; required only 10-25 microliters of extract to determine minimal inhibitory concentrations, distinguished between
