“…The main drawbacks of those mentioned techniques are that they usually required a quantity of samples and organic reagent (maceration, MAE and Soxhlet), specific instrumentation (MAE and SFE), specific fibers (SPME) or considerable time (maceration, HRE, MAE, UAE, SFE and Soxhlet). Fortunately, matrix solid phase dispersion (MSPD), as a versatile technique that integrates disruption, extraction, fractionation and purification, could overcome those drawbacks [31,32,33,34,35,36,37]. In other words, it could be realized to use less samples, organic reagent and extraction duration without specific instrumentation and fibers than the others.…”

Viticis Fructus (VF) was named Manjingzi as a commonly used traditional Chinese medicine (TCM) targeting various pains and inflammation for more than 2000 years. To guarantee the quality of Viticis Fructus, a simple, quick and eco-friendly Beta/ZSM-22 zeolites-based-mixed matrix solid-phase dispersion method (B/Z-MMSPD) was established for simultaneous extraction and determination of eight compounds (two phenolic acids, two iridoid glycosides, vanillin and three flavonoids) with different polarities from Viticis Fructus by high performance liquid chromatography coupled with a diode array detector (HPLC-DAD). Beta and ZSM-22 were mixed as the sorbent. Water, tetrahydrofuran and methanol were blended with certain ratio as the eluent. Several parameters including types of sorbents, mass ratio of Beta to ZSM-22, mass ratio of matrix to sorbent, grinding time, types, concentration and volume of eluent were optimized. The recoveries of eight analytes were within the range of 95.0%–105% (RSDs ≤ 4.13%). The limits of detection and limits of quantitation ranged from 0.5 to 5.5 μg/g and from 1.5 to 16 μg/g, respectively. Compared to the traditional extract methods, it was a simple, rapid, efficient and green method. The results demonstrated that a simple, rapid, efficient and green B/Z-MMSPD was developed for the simultaneous extraction and determination of eight target analytes with different polarities for quality control of Viticis Fructus.

“…Because of the rapidity, viability, flexibility, multifunctionality, and low cost of MSPD , various fields successfully employed MSPD, including large‐scale pesticide testing , biota fruits , milk power , cream samples , and Chinese herbs . In addition, miniaturized matrix solid‐phase dispersion (MMSPD), which requires less sample, elution reagent, and processing time in the whole procedure, has also proved to be an effective method for the extraction of inorganic iodine and iodinated amino acids and bioactive flavonoid glycosides from lime fruit . Nonetheless, no studies have been reported to extract and separate the multiple active compounds in radix polygoni multiflori by MMSPD microextraction.…”

A rapid, efficient, and green sample preparation method has been developed to extract eight active ingredients (gallic acid, catechins, epicatechin, polydatin, 2,3,5,4'-tetrahydroxystilbene-2-O-β-d-glucoside, resveratrol, emodin, and physcion) in radix polygoni multiflori by miniaturized matrix solid-phase dispersion microextraction. Simple and sensitive ultra high performance liquid chromatography combined with ultraviolet detection has been applied to analyze the multiple compounds. The best results were obtained by adding 25 mg sample into 25 mg adsorbent and grinding for 2 min with disorganized silica as adsorbent and 1 mL 150 mM 1-dodecyl-3-methylimidazolium bromide as a green eluting solvent. Good linearity (r > 0.998) for each analyte was obtained by this method. The intra-day and inter-day precision (RSD) were both below 5.31%, and the recoveries of the analytes ranged from 93.3 to 100.0%. This simple miniaturized matrix solid-phase dispersion microextraction method for analyzing the compounds in radix polygoni multiflori needs a short time and requires little sample and reagent. Thus, this method is far more eco-friendly and efficient than traditional extraction methods (reflux and ultrasound-assisted extraction). The present investigation provided a promising method for the fast preparation and discrimination of chemical differences in crude and processed radix polygoni multiflori.

“…During the MSPD procedure, type of dispersant is one of the most important parameters due to the significant variety in the adsorption capacity and selectivity of different sorbents. Molecular sieves, merged as a kind of new sorbent, has showed superior extraction efficiency in MSPD than conventional absorbents such as C 18 , modified silica, alumina and florisil . Among them, molecular sieve TS‐1 is an attractive candidate for the advantages of possessing uniform‐sized pores, high surface‐to‐volume ratio, large pore volumes, well‐defined channels, hydrothermal stability, and adjustable pore sizes .…”

A simple, efficient and environmental friendly method was proposed for determining five sesquiterpenoids of Curcuma wenyujin by MSPD extraction coupled with MEEKC separation. Molecular sieve was applied as a solid support for extraction of sesquiterpenoids for the first time. Various parameters affecting extraction and separation efficiency were investigated. The optimized conditions involved dispersing sample (200 mg) with 200 mg of TS-1 for 150 s and using 1000 μL of methanol to elute five target analytes. Finally, they were well separated by using a running buffer containing 1.3% SDS, 5.0% 1-butanol, 0.5% ethyl acetate and 10% acetonitrile in 10 mM borate buffer at pH 9.0. Consequently, the developed method was fully validated and successfully applied to determine the five sesquiterpenoids including curdine, curcumenol, germacrone, furanodiene and β-elemene in Curcuma wenyujin origin's Chinese herbal medicines. Furthermore, hierarchical cluster analysis was performed based on the contents of target compounds for distinguishing steamed and non-steamed drugs. The present study provided a promising method for fast investigation and discrimination of chemical difference in steam & non-steamed Chinese medicines from Curcuma wenyujin origin.
