Abstract
Purpose
An upsurge in health and environmental concerns over the use of synthetic color has made the development of color from cheap and easily available natural sources, namely, plants, animals, micro-organisms and algae as indispensable. This study aims to extract anthocyanins, an important natural plant pigments, from Sohiong (Prunus nepalensis). This study demonstrated that Sohiong have high anthocyanins content and antioxidant property, indicating an immense potential for the fruit producers and food processors.
Design/methodology/approach
Response surface methodology was used to optimize the conditions for extraction of anthocyanins from Sohiong using conventional solvent extraction.
Findings
The optimum conditions for extraction were found to be 36.75°C temperature, 60.32 per cent ethanol concentration and 2.39 per cent citric acid concentration with recovery of 45 per cent total extract yield, 858.84 mg C3G/100g DM anthocyanin content and 824.91 mg GAE/100g DM phenolic content with in-vitro antioxidant activity of 31.40 mmol AEAC/100g DM for FRAP and 84.66 per cent DPPH scavenging capacity (20mg/ml). The F-values and high values of adjusted determination coefficient for each response imply high level of significance of the fitted models.
Practical implications
Extracted color can be used in food and pharmaceutical industries.
Social implications
Pigment extracted is from a natural source and possesses high antioxidative activity and potential health benefits. With increasing demand for natural colors and other additives, there is a wide range of applications of the pigment as natural colorant in the food and pharmaceutical sector.
Originality/value
Selected plant source, i.e. Sohiong, was not used earlier by any researcher to extract anthocyanins for potential applications as food colorant.

Abstract
Developing economies like India have adopted the Sustainable Development Goals of sustainable cities and communities and reduced inequalities to achieve inclusive development and growth. Globally, the indigenous communities or tribals seek reparation for conflicts between proclaiming indigenous rights and claiming natural resources. There is little literature on challenges to the social inclusion of the tribes or the indigenous people. This literature review study aimed to (a) introduce the problem of social exclusion of indigenous people, (b) discuss the most researched dimensions of social inclusion of the tribal or indigenous people using relevant theoretical frameworks and (c) to develop conceptual frameworks on the theory of social inclusion of the indigenous people. PRISMA protocol was followed, and various tools were used for bibliographic management and text mining with 58 articles selected from 944 journals indexed in Web of Sciences. The analysis of the literature underscores four pivotal themes namely (1) the cultural identity of indigenous people, (2) the debate on the legitimacy of the rights of indigenous people rights and sustainable development, (3) factors impacting the social inclusion of the indigenous people and (4) coping strategies for the social inclusion of the indigenous people. The literature review highlights urgent needs to socially include indigenous and tribal people. Various factors impact the financial inclusion of the poor, including cognitive and affective factors. It is essential to leverage the skills and expertise of the local indigenous people for forest management and land management to ensure the social inclusion of the poor and tribes.
