چکیده
Penelitian pencarian agen tabir surya alami terus dikembangkan untuk mendapatkan yang lebih aman. Tabir diperlukan melindungi kulit dari bahaya sinar ultraviolet (UV). Sinar UV dapat bermanfaat bagi tubuh, namun menjadi berbahaya jika berlebih. Kemampuan suatu bahan dalam biasa dinyatakan sun protection factor (SPF). ini bertujuan mengetahui nilai SPF ekstrak metanol daun rambutan (Nephelium lappaceum). nantinya digunakan menambah wawasan mengenai potensi sebagai alami. Proses ekstraksi menggunakan metode maserasi dengan pelarut metanol. Pengukuran dilakukan secara in vitro spektrofotometri kemudian absorbansi diperoleh dihitung persamaan Mansur. menghasilkan pasta hitam kehijauan beraroma khas daun. Ekstrak konsentrasi 100, 200, 300, 400, 500, dan 1000 ppm memiliki kemampuan proteksi terhadap UV, berturut-turut sebesar 5,710; 10,398; 16,320; 20,920; 26,152; 37,983. Hasil berbeda tanaman sama terjadi dikarenakan pengambilan bagian tubuh diekstrak serta penggunaan jenis organik proses ekstraksinya. Dalam penelitian ini, pada 100 200 minimal, 300-500 sedang, sedangkan tinggi

Physicochemical Properties of Defatted Rambutan (Nephelium lappaceum) Seed Flour after Alkaline Treatment.
Rambutan seeds were subjected to SC-CO₂ extraction at 35 MPa, 45 °C to obtain defatted rambutan seed flour. Its physicochemical properties before and after treatment with alkali solution using 0.075 N NaOH were investigated. Alkali-treated flour had a significant increment in bulk density, swelling power, water adsorption capacity, emulsion capacity and stability but a reduction in turbidity, s...
متن کاملEffect of blanching on enzyme and antioxidant activities of rambutan (Nephelium lappaceum) peel
Rambutan (Nephelium lappaceum) peel is a potential source of antioxidant. As rambutan is a seasonal fruit, a proper heat treatment prior to storage is necessary. Thus, this study was conducted to determine the effect of water and steam blanchings on browning enzymes and antioxidant activities of rambutan peel extracts. Rambutan from the variety of ‘Anak Sekolah’ were peeled and the peel was bla...
متن کاملThe Effectiveness of Rambutan (Nephelium lappaceum L.) Extract in Stabilization of Sunflower Oil under Accelerated Conditions.
The oxidative properties of sunflower oil supplemented with rambutan extract, (crude extract and its fractionated fraction, SF II) in comparison with synthetic antioxidant were investigated. The supplemented sunflower oils were stored under accelerated conditions for 24 days at 60 °C. For every 6-day interval, the oxidative properties of the supplemented sunflower oil were evaluated based on th...
متن کاملAnti-Diabetic Effects of Phenolic Extract from Rambutan Peels (Nephelium lappaceum) in High-Fat Diet and Streptozotocin-Induced Diabetic Mice
Recent studies have shown that rambutan peel phenolic (RPP) extract demonstrate high antioxidant and antiglycation activities in vitro and in vivo. This study further evaluated the anti-diabetic activity of RPP in a mouse model of Type II diabetes induced by streptozotocin combined with high-fat diet. Results showed that RPP increased the body weight and reduced the fasting blood glucose level ...
