Seven prenylated stilbenes were identified by combined HPLC‐PAD‐APCI/MSn analysis of an extract of mucilage isolated from peanut ( Arachis hypogaea L.) root tips. The principal constituent was assigned the structure 4‐(3‐methyl‐but‐1‐enyl)‐3, 5‐dimethoxy‐4¢‐hydroxy‐ trans ‐stilbene. The common name mucilagin A is proposed for this novel compound. Its concentration in the mucilage was estimated at 250 σg/g (wet weight basis). The large body of literature on the anti‐microbial properties of plant‐derived stilbenes suggests that compounds detected in peanut mucilage may play a role in regulating root–soil pathogen interactions.
