Figure 2: Two-dimensional chromatographic profile at 210 nm. (a) Geranylgeraniol standard (Sigma-Aldrich), with integration, at 19.65 min. (b) Alcoholic extract marker geranylgeraniol identified and standardized, with integration, at 19.73 min. High-performance liquid chromatography-photodiode array (m, 210 nm); column, C18Zorbax (250 mm × 4.6 mm × 5 mm). Mobile phase in a gradient system; flow rate, 1.0 mL/min; and column temperature, 30°C. Empower 2.0 software
