Abstract:

Photochemical reaction in the water solution of stictosamide was studied by HPLC and LC-MS. And the main degradation product, (3S)-pumiloside, was isolated and identified by 1H NMR, 13C NMR, HRMS and optical rotation. The fragmentation patterns of (3S)-pumiloside and other intermediates were analysed by LC-MS. And then the mechanism of the strictosamide transformation into (3S)-pumiloside by light with O2 was also analysed. To improve the productivity of (3S)-pumiloside, the sunlight was replaced by light of fluorescent lamps. The productivity of (3S)-pumiloside was improved to 56% using light of fluorescent lamps and adding O2 into the stictosamide solution for accelerating degradation. This discovery shows a new green way to make the (3S)-pumiloside, and provided references for the structure transformation of similar compounds. This also gave the evidence that the strictosamide need to be stored against light.

Key words: Stictosamide, (3S)-Pumiloside, Photochemical degradation, Oxidization
