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.

Weed’s Vegetation Analysis of Centella (Centella asiatica L. Urban) Plantations
2021Co-Authors: Dian Susanti, Devi Safrina, Nur Rahmawati WijayaAbstract:Centella ( Centella asiatica L. Urban) originally is a wild plant that is being cultivated to be medicinal and cosmetics raw material. The process of Centella cultivation is relatively easy and can be grown in a variety of altitudes. One obstacle in Centella cultivation is weed growth. The proper handling of weeds in Centella plantation requires data on the weed types and characteristics. This research aimed to determine the weed types and the amount of weed found in Centella cultivation. Sampling was carried out purposively based on the presence of weeds in the cultivation area. Weed inventory was carried out using linear vegetation methods in 12 plantation beds of Centella, with a size of 6 x 2 m 2 each. Observations were made during weeding on one cropping season. Weed inventory was carried out by recording the number of species and number of individual weed and taking documentation of weeds that were recorded for identification purposes. Research data were analyzed by using vegetation analysis. The weed vegetation analysis on Centella plantations showed that there were 35 species of weeds identified from 20 plant families. Cyperus rotundus L. dominates the weed vegetation in Centella plantations because of its high adaptability and its allelochemical exudates. To sustainably cultivate the Centella, proper techniques of weed controls need to be applied by considering the nature of Cyperus rotundus L.

Treatment of Keloid with Centella Tripterpenes After Surgical Excision and X-Ray Irradiation
Chinese Journal of Dermatology, 2003Co-Authors: Zhang Guo-chenAbstract:Objective To validate the therapeutic effect of Centella Triterpenes after surgical excision and X-ray irradiation.Methods Surgical excision was performed on one hundred and six patients with keloid,after operation superficial X-ray irradiation was given to the patients.Then,they were divided into three groups:36cases in group A treated with higher dose of Centella Triterpenes;39cases in group B treated with lower dose of Centella Triterpenes;31cases took placebo as controls.All patients were followed up for12months after treatment.Results All patients were healed completely after operation.The effective rate was significantly higher in Centella Triterpenes groups than that in the control group(P0.01).No significant difference was found between the effective rates of group A and group B.Conclusions Combination therapy with Centella Triterpenes surgical operation and superficial X-ray irradiation is effective in treating keloid with mild adverse reactions.
