Drosera capensis cape sundew is a carnivorous plant native to South Africa (Jobson and Conn, 2012). Drosera capensis is also known contained the 1,4-naphthoquinones and 7-methyljuglone chemicals are used for antimicrobial and antifungal purposes and prevent tumor formation (Ziaratnia et al., 2009). In this study, Drosera capensis was propagated by tissue culture method extracted by ultrasound, soxhlet and microwave extraction methods and its 1,4-naphthoquinones content determined by HPLC method. It was concluded that different extraction methods had a significant impact on the determination of the active ingredient content in D. capensis.
