Seeds of a native aromatic plant of India, Abelmoschus moschatus (Ambrette), Malvaceae family, were considered for extraction and techno-economic evaluation in this study considering the commercial importance of unique volatile oil in the seed coat. Supercritical fluid extraction (SFE) using CO₂ as the extraction fluid was performed at different process parameters. Impact on overall yield, absolute yield, wax yield, and characteristic component was determined using the response surface methodology tool to understand the interaction of independent variables and optimise the process parameters. Maximisation of desired extract (minimum wax content and maximum content of farnesyl acetate) was found at optimum process conditions of 36.01 °C, 75 min, 109.38 bar and 3.236 ml/min flow of CO₂. Experimental readings at the predicted conditions were in good agreement with the predicted responses giving an overall yield of 5.50 %, with 96.15 % absolute and 5.578 % of farnesyl acetate in the composition. The techno-economic feasibility study at these parameters revealed that the manufacturing cost would be USD 392.5 per kg for a processing capacity of about 26.12 tons of raw material per year. The associated raw material and utility costs are the major contributing factors to the manufacturing cost. Profitability indices of net present value (NPV), internal rate of returns (IRR), pay-back time and return on investment (ROI) indicate that implementation of a supercritical fluid extraction plant is economically viable with a production of about 1430 kg of ambrette seed oil per year.

考虑到种皮中独特挥发油的商业重要性，本研究考虑对印度本土芳香植物Abelmoschus moschatus (Ambrette) 锦葵科的种子进行提取和技术经济评估。_{使用 CO 2}的超临界流体萃取 (SFE)因为提取液是在不同的工艺参数下进行的。使用响应曲面方法工具确定对总收率、绝对收率、蜡收率和特征组分的影响，以了解自变量的相互作用并优化工艺参数。_{在 36.01 °C、75 分钟、109.38 巴和 3.236 毫升/分钟的 CO 2}流量的最佳工艺条件下发现了所需提取物的最大化（最低蜡含量和最高醋酸法尼酯含量）. 在预测条件下的实验读数与预测响应非常一致，总产率为 5.50%，组合物中的绝对产率为 96.15%，乙酸法尼酯为 5.578%。这些参数的技术经济可行性研究表明，对于每年约 26.12 吨原材料的加工能力，制造成本将为每公斤 392.5 美元。相关的原材料和公用事业成本是制造成本的主要影响因素。净现值 (NPV)、内部收益率 (IRR)、投资回收期和投资回报率 (ROI) 的盈利指数表明，超临界流体萃取厂的实施在经济上是可行的，产量约为 1430 千克的 ambrette每年的种子油。
