The solvent was butan‐1‐ol : acetic acid : water (12 : 3 : 5) for 16 h followed by ethyl acetate : pyridine : water (8 : 2 : 1) for 18 h, and staining was with aniline hydrogen‐phthalate. Authentic markers were (a) Xyl₂ and Xyl₃; (b) cellobiose; (c) Glc + GalA; (d) IP; and (e) Ara, Man, Gal and lactose. IP, Isoprimeverose; Xyl2, xylobiose; Xyl3, xylotriose.
