The contents of plant sterols and fatty acids, together with the composition of fatty acids in samples of carrot (Daucus carota L.), spinach (Spinacia oleracea L.), and komatsuna (Brassica campestris L.) of different varieties harvested at different times were investigated. The total plant sterol content of the carrot samplers (35.0-50.4 mg/100 g) varied according to the variety, while there was no varietal difference in the total fatty acid content (122.9-152.1 mg/100 g). The total plant sterol content of spinach harvested in November (3.4-3.9 mg/100 g) was about twice as high as that harvested in February (1.1-1.8 mg/100 g). Among the samples harvested in February, however, there was significant varietal difference (p<0.05). The total fatty acid content of spinach harvested in February (394.0-410.2 mg/100 g) was over twice that harvested in November (136.8-191.3 mg/100 g). The total plant sterol content of komatsuna harvested in October (7.7-11.5 mg/100 g) was higher than that harvested in February (2.4-2.9 mg/100 g), being significant the difference (p<0.05). The total fatty acids content of komatsuna harvested in February (259.1-402.1 mg/100 g) was also higher than that harvested in October (81.1-161.2 mg/100 g), also being significant the difference (P<0.05). An analysis of the composition of fatty acids showed linoleic acid in carrot and α-linolenic acid in both spinach and komatsuna to be the predominant ones.
