Figure 2From: Metabolites produced by Gnomoniopsis castanea associated with necrosis of chestnut gallsMass spectra of (+)ABA 1 and 1′,4′- trans -diol (+)ABA 2. (A) Mass spectrum of (+)ABA 1 - [M + Na]+ = 287.24, [MH-H2O]+ = 247.19, [M2 + H]+ = 529.32, [M2 + Na]+ = 551.26, [M2 + K]+ = 567.30. (B) Mass spectrum of 1′,4′-trans-diol (+)ABA 2 - [M + Na]+ = 289.30, [M2 + Na]+ = 555.37.Back to article page
