GC-FID chromatograms of the fraction of steroids and neutral triterpenoids obtained from chloroform extracts of cuticular waxes of black chokeberry fruit harvested in two developmental stages (young fruit in June, and ripened fruit in September). 1—campesterol, 2—stigmasterol, 3—sitosterol, 4—sitostanol, 5—cycloartanol, 6—β-amyrin, 7—α-amyrenone, 8—α-amyrin/lupeol, 9—tremulone, 10—sitostanol, 11—oleanolic aldehyde, 12—ursolic aldehyde, 13—erythrodiol, 14—uvaol. Peaks not numbered were associated with aliphatic compounds.
