Characterization on antioxidant and physical properties of gelatin based composite films with incorporation of Centella asiatica (pegaga) extract
Journal of Food Science, 2019Co-Authors: Nur Nasihah Mohd Nazmi, N. M. SarbonAbstract:This study aimed to characterize the influence of Centella asiatica at 0.3% and 0.7% on antioxidant activities; mechanical and physical properties of chicken skin gelatin/CMC/ Centella asiatica film. Characterization of the blended films with 0.7% Centella asiatica extract shows higher antioxidant activities with a total phenolic content of 0.36 mg/g of GAE, DPPH of 89.26%, and reducing power of 0.80 nm compared to 0.3% Centella asiatica extract added where the total phenolic content was 0.29 mg/g of GAE, DPPH of 89.26% and reducing power of 0.80 nm. The addition of 0.3% of Centella extract provide higher value in tensile strength, elongation at break, melting point and transparency but lower in UV-light penetration and crystallinity of the films. While the addition of 0.7% Centella extract contributes to higher value in WVP and puncture test. In conclusion, the incorporation of Centella asiatica extracts on film greatly increased antioxidant levels and improved some of the mechanical and physical properties of the film blends.

Antioxidant, Mechanical and Physical Properties of Chicken Skin Gelatin/CMC Film Incorporated with Centella asiatica Extract
2018Co-Authors: Nur Nasihah Mohd Nazmi, N. M. SarbonAbstract:This study aimed to characterize the antioxidant, mechanical and physical properties of chicken skin gelatin/CMC/Centella asiatica blended film. The influence of Centella asiatica at 0.3% and 0.7% on antioxidant activities; mechanical properties and physical properties of chicken skin gelatin/CMC/Centella asiatica film were investigated. Characterization of the blended films with 0.7% Centella asiatica extract shows higher antioxidant activities with a total phenolic content of 0.36 mg/g of GAE, DPPH of 89.26%, and reducing power of 0.80 nm compared to 0.3% Centella asiatica extract. The addition of 0.3% of Centella extract provide higher value in tensile strength (5.0 × 10−2 MPa), elongation at break (281%), melting point (131.31 °C), transparency (0.86) but lower UV-light penetration. While the addition of 0.7% Centella extract contribute to higher value in WVP (1.13 × 10−4 g m−1s−1Pa−1) and puncture test (0.06 N). There are no significant differences between functional groups obtained from this blended film as evaluated by FTIR analysis (p > 0.05). Furthermore, XRD analysis showed the addition of extract decrease the crystallinity of film. In conclusion, the incorporation of Centella asiatica extracts on film greatly increased antioxidant levels and improved some of the mechanical and physical properties of the film blends.

Analysis of Centelloside of Pegagan (Centella asiatica)
2013Co-Authors: Noverita Sprinse Vinolina, Narendra Singh, Justin A. Napitupulu, Luthfi A. M. Siregar, Marline NainggolanAbstract:Centella asiatica is still categorized as a wild plant that has not undergone domestication. Sustainability of medicinal and aromatic plants for sustainable harvesting of medicinal plants so that it is not only in nature but also the harvest of cultivated so obtained uniform quality. Chemical constituents are already known: contain some saponin compounds, including asiaticoside, madeccasoside and asiatic acid. This study aims to determine the bioactive content; asiaticoside, madeccasoside and asiatic acid on the top (leaves and petiol) and bottom (roots and tendrils) with HPLC method. The experiment was conducted in growth chamber Department of Biological Sciences and School of Pharmacy Auburn University, USA. This study conducted in September-December 2011. The materials used are Centella asiatica of Deli Serdang accession, Kabanjahe accession, Berastagi accession and Samosir accession. Equipment needed to support the growth chamber study were digital scales, plastic pots, HPLC system types waters alliance 2695 auto sampler, 996 photodiode array detector, coulomb adsorbosphere C18 5μ, size 250 x 4.60 mm, UV absorbance, wavelength of 210 nm, flow rate 1.8 ml / min, injection volume of 20 mL, Empower Pro software, and others. The results that the pattern of centelloside (asiaticoside, madecassoside and asiatic acid), when the content of one of the high content of bioactive, the others bioactive will be lower or biosynthetic pattern toward a compound needed. Centelloside plant age affects the content of Centella asiatica. Centelloside pattern is influenced by the condition of the planting medium, very high levels of phosphorus, biosynthesis of centelloside more toward to asiaticoside.

Morphology of leaves and content of secondary metabolites asiaticoside in some accession of pegagan (Centella asiatica l. Urban) in North Sumatera
2012Co-Authors: Noverita Sprinse Vinolina, Luthfi A. M. SiregarAbstract:The objectives of this experiment was to observe morphology of leaves and content of asiaticoside in some accessions of Centella asiatica of lowland Sumatera Utara, Medan and Pantai Labu Deli Serdang and the highlands of Sumatera Utara, Berastagi, Kabanjahe and Samosir. The study also examines the link between altitude grow with the content of asiaticoside of Centella asiatica . Domestication research include: exploration and collection. This activity is carried out to collect Centella asiatica from different geographic locations with different altitudes. Later examination asiaticoside levels in the leaves of Centella asiatica by HPLC method and phytochemical test. Analysis of soil at all growing places were also conducted. The highest content of asiaticoside in accessions of Centella asiatica tested is as follows accession Deli Serdang (2.38%), Kabanjahe (1.43%), Medan (1.38%), Berastagi (1.38%), Samosir with shade (0.28%) and accession Samosir (0.24%). Altitude does not affect the content of asiaticoside Centella asiatica because in this study obtained the highest asiaticoside content found on lowland accessions namely (± 4 m asl), namely accession Pantai Labu Deli Serdang (2.38%).
