Calcium tamarind

From tamarind seed xyloglucan, carboxymethyl derivatives with different levels of DS were prepared in isopropanol medium [440]. Swelling power, solubihty and tolerance to organic solvents of the derivatives increased with increasing DS. The interaction properties of the unmodified xyloglucan with calcium chloride and sodiiun tetraborate were found to be reversed upon car-boxymethylation. 

Tamarind seeds appear to be a good source of different mineral elements (4, 6, 9, 14), such as calcium, phosphoms, magnesium and potassium (5, 20) (Table X). Calcium content of tamarind seeds is quite high compared to that of some of the cultivated pulse crops (Kuzayli et al, 1966, cited in 4)). Of all the minerals studied in 4), K is the element in highest concentration, with the values for the trace mineral copper also relatively high (6). 

Both leaves and bark are rich in tannins. Leaves yield a red dye, which is used to give a yellow tint to cloth previously dyed with indigo 13). Tamarind leaves are a fair source of vitamin C and p-carotene and the mineral content is high, particularly potassium, phosphorous, calcium and magnesium (3). 

Tamarind food supplementation enhances the excretion of excess fluoride and the retention of calcium in children living in fluoride endemic areas."...
