The best extraction solvents for simultaneously determination of chlorophyll a and b and carotene were methanol and acetone. For cherry tomatoes and tomatoes the best extraction solvent was methanol for chlorophyll a and acetone for carotene. For peppers the best extraction solvent was acetone and for cucumbers is methanol;
Variation coefficients were high, both between vegetable species and between tested varieties or hybrids.

Determination of the three pigments from different vegetables can be provided with spectrophotometric method using methanol as extractant. Beacause the methanol is toxic,extraction with acetone is preferred, providing reliable results that must be corrected with a suitable coefficient according to the vegetable species.
