Zusammenfassung:	The invention discloses a method for synchronously preparing bitter theophylline freeze-dried powder and tea polysaccharide freeze-dried powder from old bitter tea leaves. The preparation method comprises the following steps: shading bitter tea with a black sunshade net, and synchronously preparing bitter theophylline freeze-dried powder and tea polysaccharide freeze-dried powder from the shaded old bitter tea leaves by virtue of technologies such as drying, water extraction, concentration, alcohol precipitation and vacuum freeze-drying. The content of bitter theophylline in the bitter tea old leaves is increased through a shading technology, the bitter tea old leaves are used as raw materials, waste is turned into wealth, and waste of resources is reduced; the nutrition and flavor of the extract are maintained by using a freeze-drying technology, and the freeze-dried powder is high in fidelity, stable in structure and convenient to eat, carry and store for a long time. The method has the advantages of being
