UV profile and MS chromatogram of the culture filtrate the Rac56 strain and commercially available salidroside (SAL) and p-tyrosol (TYR). (a) UV chromatograms of culture filtrate of fungus Rac56 containing SAL (Rt, 2.15) and TYR (Rt, 2.51) detected at a wavelength of 277 nm; (b) UV chromatograms of authentic SAL (Rt, 2.14) and TYR (Rt, 2.49) monitored by UPLC-UV detector at the wavelength of 277 nm; (c) Molecular ion peak at m/z 299.1130 [M − H]− and m/z 345.1194 [M − H + HCOOH]− of SAL produced by Rac56; (d) Molecular ion peak [M − H]− at m/z 299.1128 and [M − H + HCOOH]− at m/z 345.1185 of authentic SAL.
