正交实验法优选茅苍术挥发油的提取工艺
Western Journal of Traditional Chinese Medicine（2020）
Abstract
目的:优选出茅苍术挥发油的最佳提取工艺.方法:采用单因素和正交实验法,优化水蒸气蒸馏法提取茅苍术挥发油的提取工艺,以挥发油的提取率为指标,考察料液比、浸泡时间、提取时间对挥发油提取率的影响.结果:茅苍术挥发油的最佳提取工艺料液比为1:10,不浸泡,超声30 min,提取8 h,茅苍术挥发油收率为4.80％,3次提取的RSD值为1.25％.结论:该提取工艺稳定可行,准确合理,为茅苍术挥发油的提取工艺提供了理论依据.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
