摘要： A Aquilaria malaccensis seed extract for use in preparation of skin care composition is provided. Multiple Aquilaria malaccensis seeds are washed for three times and drained to dry in room temperature, and are then spread on a water-absorbing material for drying in shade. The Aquilaria malaccensis seeds so dried are pulverized to a particle size not greater than 2 mm. The pulverized Aquilaria malaccensis seeds are subject to ultrasonic extraction with 90% ethanol in such a way that the pulverized Aquilaria malaccensis seeds are subjected to extraction for three times, one time for each day. After the completion of the extraction, all ethanol-water solvent is removed to obtain Aquilaria malaccensis seed extract (Crude-EtOH).
