英文摘要	In this study, a derivative of p-phenoxybenzaldehyde in bamboo shoots was investigated Bamboo shoots were ground and extracted with water, and an aqueous suspension was purified by SPE using Oasis HLB cartridges After the SPE procedure, the analytes were analyzed by HPLC with refractive index defection (HPLC-RI) In the HPLC-RI analysis for sucralose, a putative sucralose was detected In the subsequent HPLC-PDA the suspicious peak showed a unique UV absorption spectrum with the maximum wavelength at 285 nm indicating the existence of an aromatic ring The contents of the unknown compound in bamboo shoot products ranged from 001 to 0 15 mg/g The identity of the unknown compound was further confirmed by HPLC ESI/MS/MS The molecular weight of the unknown compound was determined to be 244 The chemical structure of the unknown compound was elucidated on the basis of NMR spectroscopic analyses (H-1, C-13, DEPT, COSY, HMQC, and HMBC) Finally, the structure of the unknown compound was characterized as 4-(4 dihydroxymethylphenoxy)benzaldehyde
