Abstract

Sunscreen test of  keledang (Artocarpus lanceifolius Roxb.) leaves based on in vitro method was carried out. This research aimed to investigate the property of sunscreen from methanol extract, n-hexane, ethyl acetate and methanol-water fraction of keledang leaves. The methods used include the in vitro methods by using spectrophotometer UV-Vis. Based on results of phytochemical test, it was known that  methanol extract contains flavonoids, phenolics, steroids/triterpenoids. n-Hexane fraction contains steroids/triterpenoids and quinones. Ethyl acetate fraction contains flavonoids, phenolics, steroids/triterpenoids and quinones. Methanol-water fraction contains flavonoids and phenolics. Methanol extract, n-hexane, ethyl acetate and methanol-water fraction also showed sunscreen activity based on the SPF value at a concentration of 25; 50; 100; 150; 200 and 250 mg/L. Crude methanol extract has SPF value respectively were 4.44; 7.36; 15.15; 22.47; 31.25 and 37.31 (minimum-ultra). N-Hexane fraction has SPF value respectively were 1.37; 2.24; 5.07; 7.51; 10.01 and 12.74 (minimum-maximum). Ethyl acetate fraction has SPF value respectively were 3.321; 7.20; 13.03; 19.54; 25.97 and 30.59 (minimum-ultra). Methanol-water fraction has SPF value respectively were 5.24; 10.87; 21.48; 30.89; 36.01 and 38.52 (medium-ultra). The SPF value increases with increasing concentration because the higher the concentration, the more active sunscreen compounds contained in the extract and fraction. In keledang leaves, methanol-water fraction has the highest suncreen activity folowed by methanol extract, ethyl acetate fraction and n-hexane fraction. Keledang leaves have a potency as  sunscreen agent. Keywords: Artocarpus lanceifolius; in vitro; sunscreen

Abstract

Singkil (Premna cordifolia Roxb.) is a plant that is widely found un Kalimantan. The people of Kalimantan are often used singkil leaf by as traditional medicine are believed to have medicinal properties as a cure for intestinal worms, colds, and antidiabetic. In this research, it used phytochemical screening and inhibition activity amylase test on singkil’s methanol extract. The objective of this study was to determine in-vitro enzyme amilase inhibition activity against sampel by DNS method. The result of this research was phytochemical screening in singkil’s methanol extract contains alkaloids, flavonoids, saponins and phenolics. Singkil leaf methanol extract at a concentration of 10 µg/mL can inhibit the activity of the amylase enzyme with an inhibition value of 60,93 %. Acarbose used as a positive control in this study showed activity against the amylase of 44,79 %. Amylase inhibition activity of methanol extract was higher than acarbose, the singkil leaf methanol extract has the potential as an antidiabetic drug.

Abstract

One of the causes of acne is infection by the bacteria Propionibacterium acnes. Singkil (Premna cordifolia Roxb.) is a kind of herb plant from Kutai Kartanegara which is used as a traditional herb including for acne’s treatment. This study aims to know the content of secondary metabolites compound in singkil’s extract and determine the antibacterial activity against Propionibacterium acnes KCCM 41747 bacteria. In this study, it’s phytochemical screening and antibacterial activity test using the disc diffusion method on methanol extract, n-hexane, ethyl acetate and water-methanol fractions. the result of phytochemical screening revealed that methanol extract of singkil contains alkaloids, flavonoids, steroids, and saponins. The n-hexane fraction contains steroids and the ethyl acetate fraction contains alkaloids, flavonoids, and phenolics while the water-methanol fraction contains alkaloids, flavonoids, and phenolics. The antibacterial activity test extract with a concentration of 10% showed that the diameter of clear zone of the metanol extract, n-hexane fraction, ethyl acetate fraction, and water-methanol fraction were 13 mm, 9 mm, 13,67 mm and 6 mm, respectively. The ethyl acetate fraction had the highest antibacterial activity among the four extracts. A minimum inhibitory concentration value of the ethyl acetate fraction against Propionibacterium acnes KCCM 41747 was 0,625%. The ethyl acetate fraction have the potential as an antibacterial against the bacteria Propionibacterium acnes KCCM 41747.
