SUMMARY
Uji fenolik ekstrak dilakukan dengan menggunakan FeCl 3 untuk mengetahui kandungan senyawa fenolik dari daun benalu duku hijau (Dendrophthoe pentandara (L.) Miq) dan daun benalu duku merah (Scurrula ferruginea (Jack) Danser) serta efek toksisitas telah diamati dengan metode Brine Shrimp Lethality Test (BSLT). Daun benalu duku diekstrak hingga diperoleh ekstrak methanol. Hasil pengujian ekstrak methanol menunjukkan bahwa ekstrak benalu duku hijau dan merah mempunyai potensi sitotoksik terhadap larva udang dengan nilai LC 50 masing-masing 13.95 ppm dan 22.37 ppm. Hasil tersebut menunjukkan bahwa ekstrak daun benalu duku hijau (Dendrophthoe pentandara (L.) Miq) bersifat lebih toksik dibandingkan ekstrak daun benalu duku merah (Scurrula ferruginea (Jack) Danser). Phenolic extract test was carried out using FeCl 3 to determine the content of phenolic compounds from parasite leaves of green duku (Dendrophthoe pentandara (L.) Miq) and red duku parasitic leaves (Scurrula ferruginea (Jack) Danser) and the toxicity effects that have been observed using the Brine Shrimp Lethality Test (BSLT). The parasitic leaves were extracted to obtain methanol extract. The test results of methanol extract showed that the extracts of green and red duku parasites had cytotoxic potential against shrimp larvae with LC 50 values ??of 13.95 ppm and 22.37 ppm respectively. These results indicated that the parasite leaves extract in green duku was more toxic than the extract of the red leaves parasite.
