Table 1 Yield* of autoxidation products and unreacted longifolene from reactions at 120 °C and room temperature

From: Natural autoxidation of longifolene and anti-termite activities of the products

Conditions Products** (%) Unreacted material** (%)
Temperature Time LC LA LL LAc isoLAc LHK L
120 °C 24 h 23 4.3 3.0 1.3 2.2 22
Room temperature 3 years 23 2.1 3.0 6.2 1.4 46
  1. * Each yield was calculated by dividing the molar amount of product or unreacted longifolene by the molar amount of longifolene before reaction
  2. ** L, longifolene; LC, longicamphenylone; LL, norlongilactone; LA, longicamphenylol; LAc, longifolic acid; isoLAc, isolongifolic acid; LHK, longifolene–hydroxy ketone; 100% = material longifolene
