Identification of miliacin (olean-18-en-3β-ol ME) by GC-MS, (a) Partial total ion current (TIC) chromatogram of the archaeological sample from MJR10 (Majeon-ri). (b) Partial TIC chromatogram of the modern broomcorn millet cooking experimental sample. (c) Partial TIC chromatogram of the authentic miliacin. (d) Mass spectrum of miliacin. (e) Chemical structure of miliacin. Peak identities - M: miliacin, *: stigmastanol (trimethylsilyl ether) IS: internal standard (n-hexatriacontane).
