Pre-D_2 and D_2 in raw shiitake mushroom were separated by LC. 2. Pre-D_2 was confirmed parent ion(m/z 397 [M+H]^+)to scan number 259 of total ion chromatogram. 3. D_2 was cofirmed parent ion(m/z 397 [M+H]^+) to scan number 296 of total ion chromatogram. 4. We have succeeded in obtaining mass spectra of pre-D_2 and D_2 that does not suffer from thermal ring closure.}, pages = {23--26}, title = {生椎茸中のプレビタミンD_2およびビタミンD_2の同定}, volume = {24}, year = {1993} }
