# Green Extraction of Valuable Compounds from Rubber Seed Trees: A Path to Sustainability
## 4 Significant Green Extraction for Rubber Seed Trees  
The observed trend depicted in Figure 3, where research publications focusing on green extraction methods for rubber seed trees are fewer than those concentrating on conventional techniques like Soxhlet extraction, can be attributed to several key factors. Firstly, conventional extraction methods such as Soxhlet extraction have a long history of use in the scientific community, making them a default choice due to their established track record. Secondly, researchers often gravitate towards familiar and well-understood techniques, with expertise and historical precedence playing pivotal roles in method selection. Additionally, the standardized protocols and well-defined parameters of traditional methods make them easier to replicate and compare across studies, ensuring consistency in results.  
Moreover, the availability of equipment and resources in laboratories catering to conventional techniques can pose a barrier to adopting green extraction methods, which may require additional investments. Publication bias favoring established methods in journals and a need for more awareness about the advantages of green extraction techniques can also influence researchers' choices. Furthermore, some researchers may only embrace newer green methods with comprehensive validation and standardization. Lastly, industry practices, funding considerations, and the need for alignment with existing industrial processes can further perpetuate the dominance of conventional techniques.  
In the foreseeable future, a significant shift in research trends is anticipated as awareness of environmental sustainability and the advantages of green extraction methods continue to grow. Several interconnected factors propel this transformation. Firstly, the global recognition of environmental issues, such as climate change and resource depletion, has fostered heightened sensitivity to the ecological impact of research practices. Secondly, green extraction methods inherently prioritize reduced environmental harm by employing eco-friendly solvents, reducing energy consumption, and minimizing hazardous waste generation, aligning with the prevailing sustainability ethos.  
Thirdly, regulatory and ethical considerations are coming to the forefront, with stricter environmental regulations and heightened consumer expectations necessitating environmentally responsible research approaches. Furthermore, ongoing advancements in green technology are enhancing the efficiency and reliability of these methods, making them increasingly appealing. Research funding priorities also shift towards sustainability, in

centriizing researchers to adopt green techniques. Additionally, the success stories of green extraction across diverse scientific fields erode skepticism and foster acceptance. Collaborative knowledge-sharing efforts within the scientific community and industry demands for sustainable practices further catalyze this change. As a result, researchers are poised to explore and adopt eco-friendly extraction methods, thereby contributing to a more sustainable and environmentally conscious trajectory for research and industry practices.
