Abstract

Telah dilakukan penelitian untuk menganalisis kandungan metabolit sekunder dan efektivitas antioksidan dari ektrak etanol bunga kasumba turate (Carthamus tinctorius L.), serta potensinya sebagai antihiperkolesterolemia. Bunga kasumba turate yang telah dikeringanginkan, dihaluskan dan dimaserasi dengan pelarut etanol 70%, lalu dievaporasi pelarutnya. Ekstrak etanol (EE) yang diperoleh dipartisi berturut-turut dengan pelarut n-heksana, etil asetat dan air, sehingga diperoleh ekstrak fraksi n-heksana (FH), etil asetat (FEA) dan air (FA). Selanjutnya, EE, FH, FEA, dan FA diuji kandungan metabolit sekundernya (metode Harborne) dan efektivitas antioksidannya (metode DPPH). Hasil penelitian menunjukkan bahwa EE dan FEA mengandung alkaloid, fenolik, flavonoid, saponin, tanin dan triterpenoid. FA mengandung fenolik, flavonoid, saponin, tanin dan triterpenoid. FH mengandung alkaloid, flavonoid dan triterpenoid. Efektivitas antioksidan bunga kasumba turate (dinyatakan dalam IC50) yang tertinggi pada FEA, diikuti FH, FA dan EE, dengan nilai IC50 53,59, 75,45, 77,43, dan 89.,9 µg/mL. Hasil kajian menunjukkan bahwa bunga kasumba turate dapat menghambat oksidasi LDL dan menurunkan kadar kolesterol darah. Penelitian ini menyimpulkan bahwa ekstrak bunga kasumba turate memiliki efektivitas antioksidan yang kuat dan efek antihiperkolesterolemia.Kata kunci: Antihiperkolesterolemia; antioksidan; Carthamus tinctorius L.; etanolAntioxidant Effectiveness of Kasumba Turate Flower Extract (Carthamus tinctorius L.) and Its potential as an AntihypercholesterolemiaABSTRACTResearch has been carried out to analyze the secondary metabolite content and antioxidant effectiveness of the ethanol extract of kasumba turate flower (Carthamus tinctorius L.), as well as its potential as antihypercholesterolemia. Kasumba turate flowers that have been dried and mashed, macerated with 70% ethanol solvent, then evaporated the solvent. The ethanol extract (EE) obtained was partitioned successively with n-hexane, ethyl acetate and water as solvents, so that the extracts of the n-hexane (FH), ethyl acetate (FEA) and water (FA) fractions were obtained. Furthermore, EE, FH, FEA, and FA were tested for their phytochemical content (Harbourne method) and antioxidant effectiveness (DPPH method). The results showed that EE and FEA contained alkaloids, phenolics, flavonoids, saponins, tannins and triterpenoids. FA contains phenolics, flavonoids, saponins, tannins and triterpenoids. FH contains alkaloids, flavonoids and triterpenoids. The antioxidant effectiveness of casumba turate flower (expressed in IC50) was highest in FEA, followed by FH, FA and EE, with IC50 values of 53,59, 75,45, 77,43, and 89,19 g/mL, respectively. The results of the literature review show that kasumba turate flowers can inhibit LDL oxidation and reduce blood cholesterol levels. This study concluded that kasumba turate flower extract has a strong antioxidant effectiveness and antihypercholesterolemic effect.Keywords: Antihypercholesterolemia; antioxidant; Carthamus tinctorius L.; ethanol

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan metabolit sekunder yang terdapat pada ekstrak etanol daun kalu burung, membuat masker peel-off berbahan aktif ekstrak etanol daun kalu burung dan menguji aktivitas antibakteri dari ekstrak etanol dan sediaan masker peel-off. Metode yang digunakan adalah preparasi sampel, ekstraksi, uji senyawa fitokimia, pembuatan masker peel-off, uji sifat fisik dan kimia masker meliputi uji organoleptik, stabilitas fisik, lama mengering dan pH, serta uji antibakteri. Hasil penelitian menunjukkan bahwa serbuk daun kalu burung memiliki kadar air sebesar 6.13% dan rendemen ekstrak etanol sebesar 10.34%. Ekstrak etanol daun kalu burung mengandung senyawa metabolit sekunder flavonoid, saponin, tanin, steroid dan alkaloid pada uji Dragendorff. Sediaan masker peel-off memiliki karakteristik fisik dan kimia yang aman digunakan pada kulit. Masker peel-off memiliki kisaran pH antara 5-6 dan lama mengering dengan kisaran antara 23-29 menit. Zona hambat pertumbuhan bakteri untuk ekstrak etanol daun kalu burung sebesar 12.33 mm dan masker peel-off mengandung daun kalu burung sebesar 9.67 mm. Penelitian ini menyimpulkan bahwa daun kalu burung mengandung metabolit sekunder yang memiliki aktivitas antibakteri baik dalam ekstrak etanolnya maupun dalam sediaan masker peel-off ekstrak dan mempunyai sifat fisik dan kimia yang aman.Kata kunci: antibakteri; fitokimia; kalu burung; masker peel-off Phytochemical Screening and Antibacterial Test of Peel-Off Mask with Ethanol Extracts of Kalu Burung Leaves (Barleria prionitis L.).ABSTRACTThis research aims to determine the content of secondary metabolites contained in the ethanol extract of Kalu Burung leaves, to make peel-off masks from ethanol extract of Kalu Burung leaves and to test the antibacterial activity of ethanol extracts and peel-off masks. The methods used were sample preparation, extraction, testing of phytochemical compounds, making peel-off masks, testing the physical and chemical properties of masks such as organoleptic tests, physical stability, drying time and pH, as well as antibacterial tests. The results showed that the Kalu Burung leaf powder had a moisture content of 6.13% and an ethanol extract yield of 10.34%. The ethanol extract of Kalu Burung leaves contains secondary metabolites of flavonoids, saponins, tannins, steroids and alkaloids in the Dragendorff test. The peel-off mask has physical and chemical characteristics which are safe to use. Peel-off masks have a pH range of 5-6 and drying time of 23-29 minutes. The inhibition zone of bacterial growth for ethanol extract was 12.33 mm and the peel-off mask containing Kalu Burung leaves was 9.67 mm. In conclusion, Kalu Burung leaves contain secondary metabolites that have antibacterial activity both in the ethanol extract and in the peel-off extract mask with safe physical and chemical properties.Keywords: antibacterial; kalu burung leaves; peel-off mask; phytochemistry
