Hi guys i'm also from Egypt and i have already done extensive research and experiments and I've done tons of extractions from Mimosa Hostilis and Acacia confusa so i know what i'm doing so i thought that i save you the time and effort and maybe we can collaborate together and redirect your efforts in different ways so it'd be more constructive for all of us.
my conclusions for the past four years of research are as follows :
1.)"Acacia nilotica" is Not "Acacia tortillis (Sant)" it's very easy to misidentify the two i've know the difference after years of observing and studying trees around Egypt i have trained my eyes enough to be able to identify different species.
I already obtained a fair amount of bark from both and attempted an extraction that unfortunately yielded nothing.
but maybe a very faint smell of DMT was noticed in "acacia nilotica" and i thought that maybe it contains around 0.2-0.5% DMT but won't be accessible unless after serious defatting.
2.)"Acacia Albida" can be found in upper Egypt particularly Aswan and in south Sinai which i also dug and got a fair amount of root bark and leaves which i performed an extraction on both leaves and bark seperately but yielded nothing but red oil that smelled like fuel. The trees where at least thirty to forty years old so i was highly anticipating a good yield from them after reading some reports that it contains DMT but unfortunetly not.
A side Notice to the guy stating that a 2 years old acacia nilotica would contain DMT i would say that is highly unlikely.
3.)I've been growing Phalaris brachystachys for years now and have found it to be really hard to extract anything useful from it. you have to plant a whole garden of it to be able to have enough quantities of leaves to extract from plus you have to stress them in different conditions so that the plant would have a higher ratio of DMT than 5meo and gramine.which is very time consuming and i'd rather be growing marijuana instead
Hope this will help you and i'm ready to answer any further inquires.
Salam
