Abstrakt:	Cold extract from bioluminescent earthworm Henlea sp. was studied by HPLC, 1D and 2D NMR and LC‐HRMS analysis. An abundant structural analog of the luciferin was isolated and identified as α‐C‐mannosyltryptophan (ManTrp), the product of unusual C2‐glycosylation found earlier in humans, ascidians and other animals. Two compounds in cold extract (P300b, P300c) were characterized as C2‐substituted derivatives of tryptophan. We hypothesize that a series of tryptophan‐containing compounds are possible participants of bioluminescence‐related metabolism in Henlea sp. [ABSTRACT FROM AUTHOR]
