The extracts were filtered through Whatman filter paper and evaporated to dryness using a rotary evaporator (Buchi, Switzerland) at 40°C. The dried extracts were weighed accurately (1 mg), dissolved in 1 mL of LC-MS grade methanol by sonication (Bandelin, Sonorex) and filtered through 0.22 µm syringe filter (Millipore, Germany).
The 157 and 159 UV/Vis Detectors are HPLC spectrophotometer detectors with adjustable path length flow cells. Capable of accommodating 4.6 to 50 mm ID columns, the 157 and 159 variable wavelength UV/Vis Detectors detect compounds with one or four wavelengths simultaneously with an
