Abstract: In order to produce M. oleifera (Lam.) leaf material with high glucosinolate (GS) contents in developing countries, where long transportation routes and high fluctuating temperatures are inevitable, the present study comparatively evaluated the effects of different harvesting techniques and commonly used traditional-drying methods on the stability of GS in M. oleifera leaves during post-harvest. Results revealed that sun- and ovendrying of M. oleifera leaves retained significantly higher GS contents (101.54 and 84.67 μmol/g dw, respectively) compared to solar- and shade-drying (64.46 and 45.30 μmol/g dw, respectively). Further, oven-dried leaves had significantly higher levels of GS (32.07 ± 3.50 μmol/g dw) than leaves freeze-dried after a transport of 8 h (4.03 ± 1.88 μmol/g dw). Furthermore, factors such as harvest technique (harvesting pinnae or leaflets of the plant) and the storage time influenced GS content of M. oleifera leaves.
