The antitussive, expectorant and antiasthmatic activities of different extracts from Ficus microcarpa were compared. The water fraction was purified by a ceramic membrane to give membrane fraction. The evaporated water extract was extracted with MeOH, EtOAc, n-BuOH, respectively to obtain responding fractions. The animal experimental results showed the membrane fraction had remarkable antitussive and expectorant activities. The water and MeOH fractions can obviously prolong latency time of cavy and were regarded as effective antiasthmatic fractions.
