The Camel thorn secretes a sticky liquid, which is known as manna. The principal constituent of pure manna is mannite (C6H8 [OH] 6), 90 per cent, with 11 per cent of sugar and about 0.75 per cent of impurities. Inferior sorts of manna contain mucilage, cane sugar, laevulose, dextrin, bitter substances soluble in ether, and fraxin (C16H18O10), a fluorescent glucosid resembling aesculin. Mannite (mannitol) (C6H8[OH]6, or C6H14O6) may be readily prepared from manna by digesting it in hot alcohol; on cooling, the mannite forms in tufts of silky, quadrangular prisms.
