The accumulation of different aldoximes and indole-3-acetic acid (IAA) in jasmonic acid-treated and untreated control leaves of Erythroxylum coca and E. fischeri. Twigs were cut and placed in either tap water (ctr) or jasmonic acid (200 μM) for 18 h. Aldoximes and IAA were extracted with methanol and analyzed using LC-MS/MS. Means and standard errors are shown (E. coca, n = 4; E. fischeri, n = 3). The Kruskal-Wallis rank sum test was used to test for statistical significance. P-values ≤ 0.05 indicate significant difference between the treatments. ctr, control treatment; JA, jasmonic acid treatment
