Kandungan Antioksidan Teh Hijau Daun Mangrove dan Uji Efektifitasnya Sebagai Antikolesterol Pada Mencit

Abstract

ABSTRAKPenelitian ini bertujuan untuk menentukan senyawa antioksidan teh hijau dan menjelaskan efektifitas teh hijau daun mangrove sebagai anticholesterol pada mencit. Senyawa kimia bahan antioksidaan teh hijau pada daun mangrove Bruguiera gymnorrhiza, B. parviflora, Rhizophora stylosa, R. mucronata, Lumnitzera racemosa, Ceriops tagal dan C. decandra dianalisis dengan GCMS, sedangkan khasiat teh hijau daun mangroves sebagai antikolesterol di ujikan pada mencit. Hasil penelitian menunjukan bahwa senyawa bahan teh hijau bervariasi diantara daun mangrove yaitu polifenol sederhana ditemukan pada daun semua jenis mangrove yang menjadi sampel penelitian dengan konsentrasi yang bervariasi. Senyawa katekin hanya ditemukan pada daun mangrove Ceriops decandra, L. racemosa, R. mucronata dan R. apiculata. Di sisi lain, flavonoid terdeteksi hanya pada daun C. tagal, B. gymnorrhiza dan R. stylosa, sedangkan senyawa T-flavin hanya ditemukan pada daun B. parviflora. Teh hijau daun mangrove mampu menurunkan kadar kolesterol mencit dengan kisaran 33,33 sampai 53,67% mengindikasikan besarnya potensi daun mangrove sebagai bahan teh hijau antikolesterol.Kata kunci: bahan teh hijau, polifenol sederhana, katekin, flavonoid, antikolesterol, daun mangroveABSTRACTThis study aimed to determine the antioxidant properties of green tea material in mangrove leaves and elucidate their capacity on reducing the cholesterol of mice. The chemical properties in leaves of Bruguiera gymnorrhiza, B. parviflora, Rhizophora stylosa, R. mucronata, Lumnitzera racemosa, Ceriops tagal and C. decandra were analyzed by GCMS, while their capability as anticholesterol of mice were examined. The results showed that simple polyphenols were found in all sampled mangrove leaves with different concentration, while the chatechine was found only in leaves of four mangroves including Ceriops decandra, L. racemosa, R. mucronata and R. apiculata. On the other hand, flavonoids was detected only in leaves of C. tagal, B. gymnorrhiza and R. stylosa. Meanwhile, T-flavine was detected only in leaves of B. parviflora. However, green tea material for all of sampled mangroves showed high capacity to reduce cholesterol of mice that ranging from 33.33% to 53.67%, which indicated high potentitiality of mangroves leaves as green tea material of anticholesterol.Keywords: Green tea material, simple polyphenol, cathechin, flavonoid, anticholesterol, Mangroves leaves

“…The dried samples were made into powder using a blender [4]. The simplicia that has become powder is put into a container that is protected from the sun before further processing [5].…”

“…Polyphenols are active compounds in tea that act as antioxidants. Polyphenol compounds that act as antioxidants are found in many plants [5].…”

The effect of addition mangrove leaves powder to lipid oxidation of chocolate bar during the shelf life

“…Mangroves thrive in extreme environments because of their ability to produce secondary metabolites and act as antioxidants to adapt to various extreme environmental factors on the beach. Antioxidants can protect plants against environmental stress, both biotic and abiotic and prevent the formation of Reactive Oxygen Species (ROS) free radicals that are harmful to plants [1]. The utilization of mangrove plants as natural antioxidants can replace the use of synthetic antioxidants.…”
