Apase Activity

The acid phosphatase (APase) activity in different parts of ungerminated and germinated seeds of date palm (Phoenix dactylifera L.) was investigated by enzyme assays and on polyacrylamide native isoelectric focusing gels. In the ungerminated seed, APase activity was detected in both the endosperm and the embryo, but the activity was greater in the endosperm. During seedling growth, enzyme activity in the developing haustorium and in the digesting endosperm was 10–15 times greater than that in dry seeds. The APases of the endosperm were different from those of the haustorium: (i) the molecular mass of the enzyme from the endosperm was approximately 52 000 while that of the haustorium was approximately 21 500; (ii) the pH optimum of the APases from the haustorium was 5.0, while it was between 5.0 and 6.5 for those of the digesting endosperm; and (iii) the endosperm contained 6 isoenzymes of pI 3.6–4.3, whereas the haustorium contained 14 isoenzymes with pIs ranging from 5.3 to 6.8. These observations suggest that phosphate metabolism in the endosperm is independent of that in the haustorium and that the APases for endosperm phosphate mobilization are not secreted by the embryo or the haustorium, but instead are stored in the endosperm.

Novel Antioxidants

Free radicals are implicated as a cause and consequence of diverse health pathologies including neuro-degenerative diseases, cardiovascular ailments, diabetes mellitus, cancer, nephropathies, inflammatory disorders, auto-immune diseases, idiosyncratic reactions etc. There is however a renewed interest in the study of plants for novel antioxidants. The present study evaluated the antioxidant properties of the ethanol extract of Date palm (Phoenix datylifera L.) fruit using 2,2 diphenyl-1-picrylhydrazyl (DPPH) assay and also conducted phyto-chemical analysis using standard protocols. The crude extract produced a reduced antioxidant effect compared to ascorbic acid. Specifically, at high test concentrations (0.50 and 0.25 mg/ml), the mean antioxidant activity of the extract was 65.7% and 55.2% respectively relative to 79.0% and 76.8% with ascorbic acid at the same concentration. The extract also induced an abysmally low antioxidant activity of less than 32% below 0.25 mg/ml. Phyto-chemical analysis revealed that the extract contained flavonoids, alkaloids, steroids, terpenoids and cardiac glycosides. Phoenix datylifera L. fruit could be a potential source for isolation of potent antioxidant principles..
