^aSample solution 1 mg/ml; injection volume, 1 μl; split ratio, 1/5; Perkin-Elmer PE-1 column (30 m by 0.32 mm [inside diameter]); and He (2 ml/min) as the carrier gas.

^bThe total amount of compounds 1 to 11 was defined as 100%.

^cDetermined by using a Eurospher 100-C₁₈ column (5 μm; 250 by 8 mm) and a solvent system consisting of H₂O, methanol, and CH₂Cl₂ in a gradient from 15 to 0% H₂O in 10 min, from 85 to 40% methanol in 30 min, and 0 to 60% CH₂Cl₂ in 30 min (flow rate, 2 ml/min).

^dDetermined by using GC-MS method 2.

^eDetermined by using GC-MS method 1.
