“…In another study (Kale, 1987), starch was detected at a very low concentration (1.26%) in L. Ieucocephala seeds. The galactomannan contents of whole seeds were 12.8 and 15.0% for K8 and K28, respectively; these values are lower than earlier reported values (20-25%) (Unrau, 1961;Morimoto et al, 1962;Arora and Joshi, 1985). This could be attributed to the differences in the galactomannan content in the various L. leucocephala populations studied.…”

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).

“…The seeds contain a large amount of galactomannan mucilage (20-25% yield) located in the endosperm [12,13,52,[85][86][87][88][89][90]. Galactomannan, composed of 57% mannose and 43% galactose [85], is essentially similar in composition to guar gum.…”

“…The seed gum gives highly viscous solutions at low solute concentrations [52,85,90]. Thus, L. leucocephala seeds have the potential to be used as a laxative, in vegetable soups [89], and in other commercial products [92,93].

Leucaena leucocephala is one of the fastest-growing leguminous trees. Its foliage is used as animal feed, and its leaves and seeds are used as human food in Central America, Indonesia, and Thailand. Mimosine, the toxic, non-protein amino acid in Leucaena, causes alopecia, growth retardation, cataract, goitre, decreased fertility, and mortality in non-ruminants. The mechanism of this toxicity is complicated. Mimosine probably exerts its toxic action by blocking the metabolic pathways of aromatic amino acids and tryptophan; by chelating metals; by antagonizing the action of vitamin B6; by inhibiting DNA, RNA, and protein synthesis; by exerting adverse effects on collagen biosynthesis; and by interfering in the metabolism of some amino acids, primarily glycine. Besides mimosine, other anti-nutritional and toxic factors in L. leucocephala add to its toxicity. Heat, moisture, chemical treatments, ensiling, rotation feeding, cutting management of the plant, new hybrids, introducing microorganisms into the rumen of ruminants that are unable to detoxify mimosine, and preparing protein isolate from Leucaena seeds have all been used to overcome mimosine toxicity.

“…It is also used as a substitute for coffee in some parts of the Philippines, and in the handicraft industry for making bags. The bark produces a brown dye, and the green pods are used as a vegetable in Central America and Indonesia due to its high protein and fibre contents (Arora and Joshi, 1985). Leucaena was introduced into the Kingdom of Saudi Arabia (KSA) as a fodder tree and is planted as a forestation and nitrogen-fixing tree in south and central Saudi Arabia.…”

Mutagenic Effects of Sodium Azide and Diethyl Sulphate on the Growth of Leucaena Trees (Leucaena leucocephala Lam.) Under Field Conditions

Chemical mutagenesis is one of techniques used to induce mutations and increase the genetic variability in breeding programs of economically important plants. This study aimed to evaluate the effect of different concentrations of two mutagens, sodium azide (SA) and diethyl sulphate (DES), on the growth of Leucaena leucocephala (Lam.) trees. Six concentrations of SA and DES (zero (control), 1000, 2000, 3000, 4000 and 5000 ppm) were used to soak the L. leucocephala seeds, which were planted and kept in open field at the experimental station of the Faculty of Agriculture, King Saud University, for four years. This study demonstrates that inducing SA and DES mutagens by soaking the seeds significantly affects the vegetative growth of L. leucocephala. The mutagen DES more strongly affected plant development than did SA. The concentration of 1000 ppm SA had the greatest effect on the number of branches and leaves, the stem diameter and the pod length compared to treatment with DES. In contrast, DES had the greatest effect on the plant height and the number of flowers per plant. The concentration of 5000 ppm SA had a lethal effect on seed germination and did not permit growth. The total chlorophyll content was significantly decreased under all of the studied concentrations compared with control seedlings.
