Compassion of Antioxidant Capacity of Extracts from Rabdosia Lophanthoides (Buch.Ham ex D.Don) Hara by Reflux Extraction and Decompression Reflux Extraction

WEN Ling-rong, LIN Lian-zhu, ZHAO Mou-ming (College of Light Industry and Food, South China University of Technology, Guangzhou 510640,China)  
The study compared the extraction rates of total phenols, flavonoids, tannins and antioxidant capacity of extracts from rabdosia lophanthoides (Buch.Ham ex D.Don) Hara by decompression reflux extraction and reflux extraction. The results showed that the extraction rates of total phenols, flavonoids, tannins and antioxidant capacities of extracts were influenced by solvent polarity. Using the same extraction agents, the extraction rates of total phenols, flavonoids, tannins and antioxidant capacity of extracts were influenced by different extraction methods. The antioxidant capacity of extracts by reflux extraction was higher than that by decompression reflux extraction. Several compounds including the total phenols, flavonoids, tannins, might contribute to antioxidant capacity of rabdosia lophanthoides (Buch.Ham ex D.Don) Hara. Constant material-solvent ratio and suitable extraction agents were the key factors influencing the extraction of active ingredients from Rabdosia lophanthoides(Buch.Ham ex D. Don)Hara. High temperature could improve the extraction efficiency of the effective compounds in Rabdosia lophanthoides(Buch.Ham ex D. Don)Hara.
