Chemical composition ofLeucaena leucocephalaseeds

Abstract

Studies on two varieties of Leucaena leucocephala, K8 and K28, whole seeds and seed fractions (kernel and hull), revealed that it is primarily the seed kernel portion of the seed that is a potential source of protein. Trypsin inhibitors, amylase inhibitors and cyanogenetic glycosides were found to be absent, while urease activity, amylase activity, saponins and haemagglutinins were present in the seeds. Reduction in urease activity on heating L . leucocephala seeds could be taken as an index of the reduction in mimosine content, particularly when the seeds were given high temperature treatments (e.g. autoclaving).

Partial physicochemical and nutritional characterization of the fruit of Vitex mollis (Verbenaceae)

“…The indigestible dietary fiber fraction might have a helpful physiological role, including low incidences of adenomatous polyps and colon cancer, depending on its fermentation by the colonic microflora (Saura-Calixto et al, 2000;FNB/IOM, 2002). The uvalama seed content of tannins is lower than that of some varieties of Leucaena leucocephala seeds, K8 and K28, whose content is 7.13 and 5.47 g of tannic acid/100 g, respectively (Sethi and Kulkarni, 1994). The content of phytic acid in uvalama seeds (Table 3) is within the range of some varieties of Vigna unguiculata such as CS-46, CS-88, with 8.2,9.3,9.5 and 9.4 g/100 g, respectively (Preet and Punia, 2000); however, it is higher than the observed values of some common seeds and vegetables (Oatway et al, 2001).…”

“…The ash content is lower than the one observed for some common nuts and seeds ranging from 2.49 (peanuts) to 5.24 g/100 g (pumpkin seeds) (USDA, 2002). The crude fiber in the seed of uvalama (Table 3) is higher than that of peanut and two varieties of Leucaena leucocephala, K8 and K28, whose content is 2, 16 and 13 mg/100 g, respectively (Muller and Tobin, 1986;Sethi and Kulkarni, 1994). The energy of uvalama seeds (Table 3) is lower than that of some common nuts and seeds (USDA, 2002).…”

“…Its fat content is comparable with French (2.3 g/100 g) and yellow beans (2.9 g/100 g) (USDA, 2002). The ash content of the uvalama seeds (Table 3) is low compared with two varieties of Leucaena leucocephala, K8 and K28, whose content is 6.90 and 14.22 g/100 g, respectively (Sethi and Kulkarni, 1994). The ash content is lower than the one observed for some common nuts and seeds ranging from 2.49 (peanuts) to 5.24 g/100 g (pumpkin seeds) (USDA, 2002).…”

Germination characteristics and seedbank of the alien species Leucaena leucocephala (Fabaceae) in Brazilian forest: ecological implications

“…Asynchronous flowering among and within populations, as well long flowering periods, represent strategies to avoid seed predation (Tarayre et al ., ); pre‐dispersal seed predation is important in situations in which the preferred targets are produced at specific times of the year (Munguía‐Rosas et al ., ). Post‐dispersal seed predation (as events that remove seeds from the seedbank) would not be expected to be significant in L. leucocephala , as its seeds are rich in mimosine (Sethi & Kulkarni, ), a secondary metabolite that is highly toxic to most herbivores. The soil seedbank of L. leucocephala has been found to suffer little damage from pre‐ and post‐dispersal seed predation, which contributes to its potential for population growth and successful invasion rates, in spite of having a local natural seed predator: Acanthoscelides macrophthalmus (Coleoptera: Chrysomelidae: Bruchinae) (N.G.…”

Exploration of Various Indonesian Indigenous Plants as Natural Coagulants for Synthetic Turbid Water

“…It is known that lectin in M. oleifera is the active agent in its coagulation (Okuda et al, 2001;Madrona et al, 2010), while the active agents of papaya and leucaena are still unknown. However, it is known that papaya seeds contain 27.8%w of protein (Marfo et al, 1986a), of which a 23.7%w fraction is soluble in 5% NaCl (globulin) and only 10.9% is water soluble (albumin) (Marfo et al, 1986b), while leucaena contains 57.8%w (dry basis) of protein (Sethi & Kulkarni, 1994), with a 44.9% fraction being globulin, and 29.3% albumin (Sethi & Kulkarni, 1993). …”
