In recent years, many investigations have found that artificial sunscreen additives not only have allergic and endocrine disruption problems, but also found that these additives affect aquatic organisms such as corals. Therefore, finding alternative additives to satisfy the needs of users while ensuring environmental and ecological safety has become an important issue today. Natural sunscreen additives with low toxicity, low allergenicity and high environmental friendliness have become the focus of development of new sunscreens. It is known from previous studies that the renewable parts of Garcinia subelliptica are rich in benzophenones, biflavonoids and xanthonoids, indicating potential for application in sun protection. Hence, this study evaluated the potential of the renewable parts (branches, leaves and fruits) of G. subelliptica, and combined the concept of the circular economy to make natural sunscreen additives with environment-friendly value. The results showed that the phenolic compounds and flavonoids in the renewable parts of G. subelliptica are rich, endowing them with good sun protection efficacies and antioxidant ability via absorption of ultraviolet light and scavenging of free radicals, especially the biflavonoids in the leaves. These results indicated that the extract of G. subelliptica leaves has the most potential for development as natural sunscreen additives. The active ingredients in these leaves are worth further investigate. Future research can also combine urban forestry or community forestry policies to develop the renewable parts of G. subelliptica into environmentally friendly raw materials for natural sunscreen additives with multiple functions such as sunscreen and antioxidant, enhancing the utilization values.

近年来，许多调查发现，人工防晒添加剂不仅存在过敏和内分泌干扰问题，而且还发现这些添加剂会影响珊瑚等水生生物。因此，寻找可替代的添加剂，在满足用户需求的同时确保环境和生态安全，已成为当今的重要课题。低毒、低致敏性、高环境友好性的天然防晒添加剂已成为新型防晒产品开发的重点。从以前的研究中得知，藤黄的可再生部分含有丰富的二苯甲酮、双黄酮和黄酮类化合物，表明其在防晒方面的应用潜力。因此，本研究评估了G. subelliptica的可再生部分（树枝、叶子和果实）的潜力，并结合循环经济的概念，制造出具有环保价值的天然防晒添加剂。结果表明，黄花可再生部位的酚类化合物和黄酮类化合物含量丰富，通过吸收紫外线和清除自由基，尤其是叶片中的双黄酮类化合物，具有良好的防晒和抗氧化能力。这些结果表明，G. subelliptica的提取物叶子作为天然防晒添加剂最有发展潜力。这些叶子中的活性成分值得进一步研究。未来的研究还可以结合城市林业或社区林业政策，将G. subelliptica的可再生部分开发成具有防晒、抗氧化等多种功能的天然防晒添加剂的环保原料，提高利用价值。
