Natural Red Lake Pigments Extraction from Selected Plants in Agusan Del Norte, Philippines: Characterization using Fourier Transform Infrared Spectroscopy 

Banias, Mystic P., Ciudad, Kenneth L.,


Vibrant colors are all around us, but natural pigments are gaining importance as we become more aware of environmental and health risks. In particular, while yellow is abundant in nature, red is limited. Thus, this study aims to determine the plant sources of red pigments that could help increase the production of natural dyes. Five plant samples, namely Achiote (Bixa orellana Linn.), Vine spinach or Alugbati (Basella alba Linn.), Coleus or Mayana (Plectranthus scutellarioides (L.) R. Br.), Scarlet jungle flame or Santan (Ixora coccinea Linn.), and Teak (Tectona grandis L.f.), were extracted using distilled water as a solvent with alum (aluminum potassium sulfate, KAl(SO4 )2 · 12H2 O) as a mordant at a ratio of 1:50. The resulting dye extracts were then treated with 25 g of sodium carbonate Na2 CO3 to extract red lake pigments. The results showed that the extracted lake pigments varied in color, with orange, white, green, reddish-brown, and brown, respectively. While red lake pigments were not produced, the findings suggest the potential for increased natural dye production and provide a promising source for further investigation to support research on natural pigments

The Journal of Ecosystem Science and Eco-Governance is pleased to introduce a valuable addition: POLICY BRIEFS, a new article type aimed at facilitating meaningful engagement between researchers and policymakers, especially concerning studies with direct policy implications. This unique format is designed to provide policy professionals with easily accessible summaries of research papers published in our journal. These succinct Policy Briefs encapsulate the essence of a research study and its policy-related implications in a concise, high-level manner. Our goal is to empower both non-experts and those with limited time resources by offering them a clear grasp of the research's policy context and findings. We aim to distill key policy insights from each study, enabling readers to effectively utilize these findings. We invite you to explore the JESEG Guide for Authors https://bit.ly/GuideToAuthors_2023 and the policy brief template provided https://bit.ly/JESEG_PolicyBriefTemplate.
