The extractives from leaves of Acacia hybrid
Keywords:
Acacia hybrid, extractives, neutral substances, organic acidsAbstract
This paper presents the results of the preliminary studies of extractives
from leaves of Acacia hybrid. Some chemical compositions of the leaves
have been identified, the method of extraction in petroleum ether and
acetone has been applied, several methods for improving the extraction
effectiveness were studied. After separation of the extractives dissolved in
petroleum ether, some target products were quantified such as organic
acids, neutral substances and sodium chlorophyll. Organic acids of up
0.61 to 1.82%, neutral substances of up 2.13 to 5.43 and sodium
chlorophyll of up 0.16 to 0.23% of dry leaves weight were obtained. An
UV - VIS spectrum of sodium chlorophyll wasused for identifying the
preliminary composition of organic acids and neutral substances. Analysis
of leaves powder extracted by petroleum ether showed that the crude fiber
content and nutritional contents were comparable with some kind of
animal feed additives, such as sweet potato leaves, soybean stems and
banana stalks. The research results are the base for the further study of the
utilization of natural products from acacia leaves.
