ABSTRACT: Measurement of the
fluorescence comportment of Bougainvillea
xbuttiana flowers embedded in silica xerogels matrix prepared with two
different water to tetraethyl-orthosilicate [Si(OC2H5)4]
ratio molar of 11 and 5, without heat-treatment, we report the grade of
biostability of compound. The structural comportment for the PSI and PSII
present in Bougainvillea flower is
similar to the structural comportment for these photosystems present in leaves
when they are incorporated on inorganic matrix such as silica xerogels. The
contribution of the natural pigment of this kind of flower such as betalains which
consist of betaxanthins and betacyanins, determines their colors contributed in
the range of wavelength from about 550 nm to 660 nm.
