Identification of three major peaks isolated from pulp extracts at 280 nm^a

Peak number	Rtb min	UV max	MS, m/z [M-H]−	MS/MS, m/z base ion	Phenolic identification
P2	6.2	261	299	137	p-hydroxybenzoylhexose
P3	7.6	315 (228)	325	163	p-coumaroylhexose
P7	11.5	285	643	333	unknown

^aSemi-purified ethyl acetate extracts derived from crude 80% methanol pulp extracts

^bRetention times of these major peaks are based on the LC-UV/vis profile.
