Exhaustive hydro-distillation of the bark, heartwood and fruits of Cryptocarya massoy (Lauraceae) afforded pale yellow-coloured oils in 0.7, 1.2 and 1.0 % yields, respectively. Detailed chemical evaluation of these distillates using GC/MS revealed the major components in the bark and the heartwood oils to be the C-10 (5,6-dihydro-6-pentyl-2H-pyran-2-one) and C-12 (5,6-dihydro-6-heptyl-2H-pyran-2-one) massoia lactones, while the major fruit oil constituent was benzyl benzoate (68.3 %). The heartwood also contained trace amounts of the C-14 (5,6-dihydro-6-nonyl-2H-pyran-2-one) massoia lactone (1.4 %) and the saturated C-10 derivative delta-decalactone (2.5 %).
对樟科琼楠属植物琼楠（Cryptocarya massoy）的树皮、心材和果实进行彻底的水蒸馏，分别得到了产率为0.7%、1.2%和1.0%的浅黄色油状物。使用气相色谱-质谱联用仪（GC/MS）对这些馏出物进行详细的化学分析，结果显示树皮油和心材油中的主要成分是C-10（5,6-二氢-6-戊基-2H-吡喃-2-酮）和C-12（5,6-二氢-6-庚基-2H-吡喃-2-酮）的肉豆蔻内酯，而果实油的主要成分是苯甲酸苄酯（68.3%）。心材中还含有痕量的C-14（5,6-二氢-6-壬基-2H-吡喃-2-酮）肉豆蔻内酯（1.4%）和饱和C-10衍生物δ-癸内酯（2.5%）。
