The invention discloses a taxol microcapsule as well as a preparation method and a detection analysis method of the taxol microcapsule. According the taxol microcapsule as well as the preparation method and the detection analysis method, gingko octenyl succinic acid modified starch is taken as a wall material, taxol is taken as a core material, the taxol microcapsule is prepared by adopting the spray drying technology, the preparation method is simple, the cost is low, and the preparation method is suitable for industrial production. According to the detection a method, taxol is taken as the reference substance, by detecting the embedding rate, the in-vitro dissolution rate and the release condition, the complete and advanced production system and the detection standard which is strong in specificity and is controllable are formed, thus the effective control over the quality of the medicine is improved, and the quality and curative effects of the taxol microcapsule are guaranteed.
