Fluorescence detection of phototoxic psoralens in vegetable products

This work describes the fluorescence detection of phototoxic in various vegetable products including celery, lime, carrot, parsley, and spinach. The spectral properties of psoralen, 5-methoxypsoralen, and 8-methoxypsoralen and raw extracts of celery and carrots are discussed in detail. The measureme...

Description
Summary:This work describes the fluorescence detection of phototoxic in various vegetable products including celery, lime, carrot, parsley, and spinach. The spectral properties of psoralen, 5-methoxypsoralen, and 8-methoxypsoralen and raw extracts of celery and carrots are discussed in detail. The measurements used a portable fiberoptics luminoscope developed for monitoring surface and skin contamination.
