The major phloem sap components are carbohydrates. Analyses of the phloem exudates from various plants have shown that sucrose is the major transportable form of carbohydrate. In some species of Cucurbitaceous, in addition to sucrose, certain oligosaccharides like raffinose, stachyose, and verbascose have also been found in the phloem sap composition.
Again in some cases sugar alcohols mannitol and sorbitol or dulcitol have been found in the phloem exudates. Generally, the seaweeds produce large amounts of mannitol. Phloem exudate rarely contains hexoses even though glucose and fructose are commonly present in phloem tissue. They are the products of sucrose hydrolysis and are distributed in non-conducting cells to enter directly into the metabolism.
