It is 1 by cyclodextrin and salicylic acid mass ratio:2 are added in the deionized water of 90 times of cyclodextrin quality, room temperature Ultrasonic disperse 5 minutes, then heating in 70 DEG C of water-baths is transferred them to, 400rpm is stirred 1.5 hours, obtains salicylic acid-ring paste Inclusion compounds solution；Maltodextrin and side chain are formed sediment with the amount that 0.8g maltodextrins and 1.5g amylopectin are added in every 100g water respectively Powder is added in salicylic acid-cyclodextrin inclusion compound solution, and then at 80 DEG C, 400rpm stirrings obtain salicylic acid solution in 0.8 hour, make Salicylic acid fully dissolves, then again respectively by adding per 100g water the amount of 0.35g shitosans and 0.75g Arabic gums by shitosan Salicylic acid solution is added to Arabic gum, is stirred 0.75 hour in 80 DEG C, 400rpm, it is fully dissolved, thus obtain end Solution, then whole solution is spray-dried, obtain water-soluble salicylic acid microballoon.Described spray drying is that salicylic acid solution is carried out into rapid draing using spray dryer, sets drying condition For：Feeding temperature is 130-220 DEG C, and sample introduction flow velocity is 20mL/min, and air mass flow is air pressure 0.3Mpa, and drop temperature control exists Between 60-100 DEG C, collect uniformly, tiny white powder, as water-soluble salicylic acid microballoon.
Pharmaceutical field: water soluble salicylic acid can be used in medicine to relieve pain and fever, as well as anti-inflammatory effect.
Agriculture: Agricultural water-soluble salicylic acid is a phenolic hormone, which can regulate the growth and development of plants.
