Semipurified saline extracts of seeds from Crotolaria juncea, Cassia marginata, Ficus racemosa, Cicer arietinum (L-532), Gossipium indicum (G-27), Melia composita, Acacia lenticularis, Meletia ovalifolia, Acacia catechu and Peltophorum ferrenginium were tested for leukoagglutinating activity against whole leukocytes and mononuclear cells from patients with chronic myeloid leukaemia (34), acute myeloblastic leukaemia (5), acute lymphoblastic leukaemia (7), chronic lymphocytic leukaemia (3), various lymphoproliferative/haematologic disorders (54), and normal healthy subjects (50). In addition, bone marrow cells from three patients undergoing diagnostic bone marrow aspiration and activated lymphocytes from mixed lymphocyte cultures (MLC) were also tested. All the seed extracts agglutinated white blood cells from patients with different types of leukaemia. But none of them reacted with peripheral blood cells of normal individuals, patients with various lymphoproliferative/haematologic disorders or cells from MLC. Leukoagglutination of leukaemic cells with each of the seed extracts was inhibited by simple sugars. Only in one instance, cells from bone marrow of an individual who had undergone diagnostic bone marrow aspiration for a non-malignant condition were agglutinated. It is felt that purification of these seed extracts may yield leukaemia-specific lectins.

The extract enriched in total oligomer flavonoids (TOF), and the aqueous, methanol, and ethyl acetate extracts of Acacia salicina were investigated for their polyphenolic compound content, antioxidative activity in the nitro blue tetrazolium/riboflavin assay system, antibacterial activity against Gram-positive and Gram-negative bacterial reference strains, antigenotoxic activity tested with the Ames assay, and cytotoxic activity against the K562 human chronic myelogenous leukemia cell line and L1210 leukemia murine cells. TOF extract was effective at inhibiting nitro blue tetrazolium reduction by superoxide radical in a nonenzymatic O(2)(*-)-generating system. Significant activity against bacterial reference strains Staphylococcus aureus, Enterococcus faecalis, Salmonella enteritidis, and Salmonella typhimurium was shown with all the tested extracts. These extracts significantly decreased the genotoxicity induced by sodium azide and 4-nitro-o-phenylenediamine. A pronounced cytotoxic effect on both leukemia cell lines was detected in TOF, methanolic and ethyl acetate extracts. The antioxidant, antimicrobial, antigenotoxic, and cytotoxic activities exhibited by A. salicina depended on the chemical composition of the tested extracts.
