ISOLASI, KARAKTERISASI DAN AKTIFITAS RADIKAL BEBAS DPPH SENYAWA METABOLIT SEKUNDER DARI FRAKSI ETIL ASETAT DAUN KOKANG (Lepisanthes amoena (Hassk) Leenh.)
Abstract:Kokang (L. amoena (Hassk) Leenh.) merupakan tanaman lokal Kalimantan Timur dan digunakan sebagai alternatif pengobatan oleh suku dayak untuk mengatasi berbagai masalah kulit, diantaranya menghilangkan noda hitam di wajah, menyembuhkan bekas luka cacar, bekas jerawat dan perawatan kulit (skincare). Penelitian ini bertujuan untuk memperoleh isolat senyawa metabolit sekunder yang memiliki aktivitas antioksidan dan mengetahui struktur kimia dari isolat tersebut. Metode yang digunakan adalah ekstraksi secara masera… Show more
“…Antioxidants was an organic compound that can dampen free radicals in the human body by an oxidation process. Free radicals are relatively unstable molecules with atoms that have one or more unpaired electrons in their outer orbits (Kuncoro et al, 2022). Both of the extract has potential compound that have antioxidant activity.…”
The illnesses brought on by free radicals are a common source of health issues. Pathogenic processes and tissue damage are both significantly influenced by free radicals. Natural ingredients from Indonesia has been carried out for generations by the community with various kinds of treatments according to existing tribes, for example, such as kelulut bee (Tetragonula testaceitarsis) propolis and kokang (Lepisanthes amoena) leaves. Stingless bee propolis has several bioactivities to prevent diseases. The research about T. testaceitarsis propolis still limited. The purpose of this research to find out whether the combination of T. testaceitarsis propolis and L. amoena leaves extracts has antioxidant activity. Ethanol extract T. testaceitarsis. propolis and ethanol extract L. amoena leaves was collected and then tested for antioxidant activity using the DPPH method. The results showed that all three concentrations had very strong antioxidant activity. T. testaceitarsis propolis extract (50%) combined with L. amoena leaves (50%) showed strong antioxidant activity (92%) in 25 ppm concetration. Then 75% T. testaceitarsis propolis extract and 25% L. amoena leaves extract had the highest antioxidant activity (95%) at a concentration of 50 ppm concentration. This strong antioxidant activity was prospected to be continued as a pharmaceutical product.

“…Moreover, empirical evidence supports its effectiveness in addressing various skin issues, including the removal of facial black spots and the healing of acne and smallpox scars. 7,8 The leaves can also be ground into powder for skin protection against sun exposure. 9…”
Therefore, this study aims to determine the saponins content using LC-MS, the cytotoxicity against shrimp nauplii, and the antioxidant activity of L. amoena bark and leaves as well as Fordia splendidissima (Blume ex Miq.) Buijsen) leaves.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
