Mature Seeds

Polyamines of 18 leguminous mature seeds were analyzed by high-performance liquid chromatography and gas chromatography – mass spectrometry. Putrescine, spermidine, and spermine occurred ubiquitously and cadaverine, agmatine, and homospermidine were sporadically found in these seeds. Six unusual polyamines, i.e., canavalmine [NH2(CH2)4NH(CH2)3NH(CH2)4NH2], homospermine [NH2(CH2)4NH(CH2)4NH(CH2)4NH2], aminopropylcanavalmine [NH2(CH2)3NH(CH2)4NH(CH2)3NH(CH2)4NH2], thermospermine [NH2(CH2)3NH(CH2)3NH(CH2)4NH2], and aminopropylhomospermidine [NH2(CH2)3NH(CH2)4NH(CH2)4NH2] were found in the seeds of Pisum sativum. Thermospermine and aminopropylhomospermidine were also detected in the seeds of Vicia hirsuta and Trifolium pratense, respectively. An unusual tetraamine, norspermine [NH2(CH2)3NH(CH2)3NH(CH2)3NH2], was found in the seeds of Medicago sativa and Vicia faba. The seeds of Phaseolus coccineus contained homospermine and a tertiary branched pentaamine, N5-aminobutylhomospermine [NH2(CH2)4N((CH2)4NH2)(CH2)4NH(CH2)4NH2]. Key words: poly amine, legume, seed.

Cucurbita species ( Cucurbita moschata and Cucurbita maxima) are rich sources of nutrients, especially carotenoids and carbohydrates. Metabolites in pulps of C. moschata and C. maxima lines were examined by high-performance liquid chromatography and gas chromatography–mass spectrometry. Our results revealed that glucose and sucrose were the dominant sugars in C. maxima and C. moschata, respectively. A correlation was found between Brix percentage and sucrose levels as compared with glucose and fructose. A greater amount of myo-inositol had accumulated in C. moschata lines compared with C. maxima. Conversely, total carotenoids and antioxidant activity were found to be higher in C. maxima lines than in C. moschata. A strong correlation of glucose, fructose, and sucrose with β-carotene and violaxanthin revealed that it will be difficult to develop pumpkin cultivars with both high inositol and carotenoid levels. In conclusion, the composition of carbohydrates and carotenoids was more diverse in C. moschata lines than in C. maxima lines. Our results will contribute to a better understanding of metabolite changes in the fruits of these as well as other pumpkin species.
