Optimal conditions of MAE of triterpene glucoside were determined as: duration of microwave radiation 5min, microwave power 495W, size of raw material less than 0.15mm, and ratio of liquid to solid 30:1. Comparing with conventional heating extraction, MAE of triterpene glucoside from Siraitia grosvenorii showed advantages of less time and high extraction rate.
The time used with MAE is only 5 min with 76.56% extraction rate, while the conventional extraction method took two hours with about 68.46% extraction rate. This novel method is suitable for fast extraction of triterpene glucoside from Siraitia grosvenorii.
Because the number of molecular descriptors greatly exceeds the number of observations, conventional regression methodologies are not useful in such studies.
The conventional and predictive correlation coefficients were found to be 0.725 and 0.577 for the antiproliferative activity of aminophenylbenzamides and acrylamide series, respectively.
Detectability of 0.7 mg/l for pseudoephedrine hydrochloride was achieved at a sample throughput rate of 24 times per hour, which is 30% lower than that obtained by HDI-based conventional CE.
This is an improvement compared to that obtained by HDI-based conventional CE.
Analytical results for two batches of compound ibuprofen tablets by the SEKI-based FI-CE approach were in good agreement with that obtained by a conventional high performance liquid chromatographic method.
