Title: Variations in the Pharmacognostic properties of Aegle Marmelos found across five geographical locations in Sri Lanka Authors: Sampath, S. D. L. R.; Hapuarachchi, S. D.; Madhushik, K. D. C. Abstract: Aegle marmelos (Bale tree), family-Rutaceae is a very important medicinal plant used for the Ayurveda and traditional medical systems. This study is focused on pharmacognostic characteristics of the leaves, stem barks and the root barks of Aegle marmelos (A. maemelos) found in five geographical locations in Sri Lanka. A solvent system containing, Toluene, Ethyl acetate, Formic acid and Methanol was used as mobile phase for the leaves. For stem bark and root bark extracts, Toluene: Ethyl acetate: Chloroform: Hexane: Methanol solvent system was used as the mobile phase. TLC outcomes were developed by High Performance Thin Layer Chromatography (HPTLC) technique. According to this study moisture values of the selected plant parts were in the range of 7% to 12% and ash values were in the range of 5% to 10%. pH values of the selected plant parts were varied form 5-8. Microscopic view of the root bark and stem bark were observed and tracheid and xylem vessels were detected. One common compound was detected in leaves, stem bark and root bark, and two common compounds were detected in stem bark and root bark from TLC and HPTLC profiles. It was detected that the concentrations of the similar compounds vary with plant part as well with the origin of the plant. These findings can be used for the identification and authentication of A. marmelos plant parts that are used for medicinal purposes and herbal product manufacture. A comparative clinical study is needed to explore the therapeutic efficacy of these parts.

Title: The impact of food safety knowledge and attitude of food handlers on street food quality: the mediating impact of food safety practice Authors: Rathnayake, R. K. S. R.; Karunarathne, A. C. I. D.; Bandara, W. M. A. H. Abstract: Street food is a growing segment of gastronomic tourism. The quality of street food continues to the stage in society as a source of foodborne diseases. Therefore, this study examined the quality level of street foods in Sri Lanka and how street food handler’s knowledge and attitude of food safety effects on food quality when food safety practices play the mediating role. Data were collected using a structured questionnaire from 200 street food handlers from the Colombo district of Sri Lanka using convenience sampling technique and analyzed using descriptive statistical analysis and structural equation modeling. Research findings revealed that the current level of street food quality in Sri Lanka is at a satisfactory level and the knowledge, attitude and practices on food safety of street food handlers also proven to be positive. Moreover, food safety knowledge, attitude and practices positively impacted on street food quality and food safety practices mediate the association. Therefore, the values of Sri Lankan street foods should be promoted in order to avoid criticism of street foods. Training and development programs should be implemented by responsible parties while strengthening the rules and regulations related to food quality to improve the status of street foods as there is still room for improvements. The results of this study will be useful to public health professionals, government agencies, destination promoters, food tourism promoters, future researchers and all other parties interested in street food.
