Determination of Vitamins D₂ and D₃ in Edible Fungus by Reversed-Phase Two-Dimensional Liquid Chromatography

Table 2

Obtained results with different extraction solvents (n = 6).

Vitamin content after extraction by different solvents (±SD, μg/100 g)
	n-Hexane/ethyl acetate (4/6)	n-Hexane	Ethyl acetate	Isooctane	Petroleum ether
VD2	85.2 ± 2.6	86.6 ± 4.8	86.7 ± 2.4	77.2 ± 4.5	85.7 ± 4.9
VD3	88.2 ± 4.1	87.1 ± 4.4	90.1 ± 5.2	89.1 ± 3.9	89.2 ± 4.5

Note: VD₃ was spiked into sample with a level of 100 μg/100 g.
