Separate HPLC fractions of the extractable peaks were dried using a Büchi Rotavapor R-124 rotary evaporator (Brinkmann Instruments, Inc., Westbury, NY), redissolved in 0.5 mL of 0.5 M methanolic HCl, and the resulting solution was heated for 1 hour at 70 • C. The hydrolysates were then dried and dissolved in 40 μL of 0.2 M TMAH in methanol to produce the methyl derivatives, which were subsequently analyzed using Agilent 6890/5973 gas chromatograph-mass spectrometry detector, GC-MSD (Wilmington, DE) equipped with a Gerstel MultiPurpos-eSampler MPS (Baltimore, MD). The gas chromatograph was fitted with Agilent DB-5MS capillary column (0.25 μm × 30 m, 0.25 μ film) and operated with temperature programming from 50 • C (held for 1 min) to 300 • C at 10 • C/minutes, and held at 300 • C for 6 min using helium as the carrier gas at a constant flow rate of 1 mL/min. The GC injector port was set at 280 • C in a splitless mode and the MSD was maintained at 280 • C. All the GC/MS **data** were acquired with MSD ChemStation Version D.01.02.16 (Agilent Technologies, Wilmington, DE) in the m/z range of 30-500 at a rate of 1 scan/sec under electron ionization (EI) mode. laminate extract was analyzed by LC/MS in full-scan positiveion mode using a 50 to 1500 m/z scan range. Following the assignment of MS ions for the identified peaks, the extract was reanalyzed using full-scan MS/MS experiments to obtain product ion spectra.
