Abstract:
The study on the amount of mimosine content for the two plant species namely Mimosa pigra L. and Leucaena leucocephala Lam. Showed that there was no mimosine in Mimosa pigra L. while while mimosine was found present in all parts of Leucaena leucocephala Lam. And the amount represented by average percentage per dry weight of the plant arranged from high to low values were : seeds 6.91%, young leaves 5.75%, flowers 5.66%, pods 5.25%, mature leaves 3.09%, petioles 1.82% roots 1.33%, and stems 0.42% If nitrogen of mimosine were substracted from total nitrogen, it was found that protein content in young leaves and seeds of Mimosa pigra L. were higher than Leucaena leucocephala Lam, in mature leaves petioles and stems in both plants were almost the same except flowers, pods and root which Leucaena leucocephala Lam. were higher than Mimosa pigra L. The amount of protein content in each part of Mimosa pigra L. were as follows:-seeds 27.99% young leaves 26.94%, mature leaves 24.08%, flowers 19.52%, pods 18.72%, petioles 9.67%, roots 4.97% and stem 4.18%. Protein content in Leucaena leucocephala Lam. were:- young leaves 25.63%, seeds 25.57%, mature leaves 24.65%, pods 21.58%, flower 21.26%, petioles 9.51%, roots 5.76% and stems 4.28%. Seasonal variation also had an effect on growth, mimosine and protein content, it was found that growth rate of both plants during raining season were higher than summer and winter season. Protein content in Mimosa pigra L. during the raining season were higher than the other seasons, but in Leucaena leucocephala Lam. protein content when substracting nitrogen of mimosine content in Leucaena leucocephala Lam. were higher during raining season than summer and winter season.
