The column chromatography combined with ultrafiltration was applied to the purification of fruit bromelain.

An improvement to the producing technology of fruit bromelain;

A Study on Concentration and Extraction of Bromelin with Ultraf iltration Method;

Study on the Immobilization Technology of Bromelin with Attapulgite Modified by 3-aminopropyltriethoxysilane;

he contents and the activities of bromelin in organs of pineapple,and the protection of enzyme activities during extracting process were investigated.

Study on extraction of bromelain from pineapple;

Study on the effect of bromelain;

Study on the Stability of Bromelain Storage;

The paper studied the factors of influencing the inducement and growth of pineapple callus; effect of the composition of culture media and other external factors on suspension culture of pineapple cells; accumulation of bromelains during solid and liquid cultures and conditions for inducing pineapple tube plantlets, etc.

Objective To investigate the enzymatic debridement effect of bromelain ointment on guinea pigs with third-degree burns.

In this study, in order to prepare a bromelain ointment, crude bromelain was refined, the separated fractions effects with debriding were tested, a preparation and its ability to debride in vivo were studied.
