“…Among these researches, evaluation of the edible oil authenticity to detect adulteration or spoilage can be mentioned (Aparicio, Rocha, Delgadillo, & Morales, 2000; Escuderos, García, Jiménez, & Horrillo, 2013; Gan, Tan, Man, NorAini, & Nazimah, 2005; Martın, Oliveros, Pavón, Pinto, & Cordero, 2001; Pacioni, Cerretani, Procida, & Cichelli, 2014). Moreover, E‐nose was employed to detect oxidation in soy oil (Yang et al., 2000), oxidation degree of ultra‐virgin olive oil (Cosio, Ballabio, Benedetti, & Gigliotti, 2007; Lerma‐Garcia, Simo‐Alfonso, Bendini, & Cerretani, 2009), auto‐oxidation of canola oil (Mildner‐Szkudlarz, Jeleń, & Zawirska‐Wojtasiak, 2008), magnolia biondii pamp (Nie et al., 2020), camellia oil authentication (Shi, Wu, Jin, & Wang, 2020), detection and discrimination of plant oil scents and their mixtures (Okur et al., 2020), and edible olive oil characterization and shelf life assessment (Buratti, Malegori, Benedetti, Oliveri, & Giovanelli, 2018).…”

Foodstuff adulteration involves addition of any low‐cost substances to the high‐price materials to reduce the content of the expensive components, and hence decrease the production cost and reach to the maximum profit. An electronic nose was used in this study to detect the adulterations in mixed edible oils. The acidity, peroxide, anisidine, and Totox values of the edible oil samples were measured according to the official American Oil Chemist Society (AOCS) standard. The results were analyzed by Cluster analysis (CA), principle component analysis (PCA), principal component regression (PCR), linear discriminant analysis (LDA), and artificial neural network (ANN) methods with accuracy of 95, 98, 98, 88, and 97.3%, respectively. According to the results, the ANN method with structure of 8‐7‐5 showed the highest accuracy in classification of oil adulteration. Its correct classification ratio, mean square errors, and correlation (r) were 97.3%, .117211, and .0963, respectively. The results also indicated that the proposed method can be used as an alternative of the official AOCS methods to innovatively detect the edible oil adulteration with high accuracy and speed. Practical applications Lipid oxidation is one of the major causes of food spoilage especially in those containing oil. AOCS has developed various methods to evaluate the oxidation status of the oil assets. However, these chemical tests are time‐consuming, destructive, and costly and require several glassware and reagents. E‐nose could be used for real‐time monitoring of the volatile components of the food to evaluate different features of the product. Generally, E‐nose evaluates mixture of smells released form a sample and is a reliable, nondestructive, cost‐effective, and portable method with high feasibility and speed as well as simple use. CA, PCA, and ANN methods were also applied for qualitative differentiation of different adulteration percentages in oxidized and nonoxidized oils.

“…EOSA was extracted using a model Multisynth microwave extractor (Milestone, Italy). The extraction conditions were referred to as the methods described in the previous study with slight modification (Nie et al., 2020). The specific operations were that 10 g of star anises powders were mixed with water in a ratio of 1:10.…”

A sensitive and selective method of ultra‐fast GC electronic nose (E‐nose) coupled with chemical methodology was developed for both identifying the chemical constituents of essential oil from star anise (EOSA) and the screening of the radical scavenging activity of each compound in EOSA quickly without the isolation of monomers by comparing the change of the chromatographic peak area of every component in EOSA before and after the reaction with the free radicals. The results showed the main components of EOSA were anethole (36.42%), limonene (20.77%), α‐terpinene (6.51%), and α‐phellandrene(5.61%). Among all chemical components, p‐menthatriene showed the strongest scavenging ability both in 1,1'‐diphenyl‐2‐picrylhydrazine (DPPH) and hydroxyl (OH) radicals, and p‐cymenene showed the strongest scavenging ability in 2,2'‐azino‐bis(3‐ethyl‐benzothiazoline‐6‐sulphonate) (ABTS) radical, with scavenging rates of 93.00 ± 0.56%, 79.50 ± 0.78%, and 70.80 ± 0.32%, respectively. The reliability and feasibility of using E‐nose to identify chemical constituents of EOSA were verified by gas chromatography‐tandem mass spectrometry(GC‐MS/MS). Practical applications The essential oils are the complex mixtures and important constituents in natural edible spices. How to evaluate and screen the radical scavenging activity of each component in the mixtures is a very challenging project. The traditional chemical methods are mainly used to evaluate total radical scavenging activity and antioxidant activity of essential oils. The compounds in the mixture need to be separated into individuals in advance if we want to know the bioactivity of each component and their radical scavenging activity in the past. The paper has developed a simple and convenient ultra‐fast GC E‐nose method. This method can not only quickly identify the chemical components of essential oil from star anise, but also quickly evaluate the radical scavenging activity of each compound in the essential oil from star anise. The proposed method can be applied to almost any other essential oils and volatile mixtures.

The objective of this paper was to develop a preparative method for the separation and purification of phaseoloidin, entadamide A, and entadamide A-β-Dglucopyranoside from the crude extract of Entada phaseoloides by high-speed countercurrent chromatography (HSCCC) for the first time. Optimized by orthogonal experiments, the extraction conditions were extraction temperature of 65 C, solidto-liquid ratio of 1:15 (g/mL), ethanol concentration of 40%, and extraction time of 2.5 h. Using n-butanol-acetic acid-water (4:1:5, v/v/v) as the two-phase solvent system, 38.79 mg phaseoloidin (the purity was 99.3% with a recovery of 98.1%), 34.85 mg entadamide A (the purity was 96.4% with a recovery of 98.5%), and 33.97 mg entadamide A-β-D-glucopyranoside (the purity was 98.6% with a recovery of 97.7%) were obtained from 500 mg crude extract by HSCCC in head-to-tail elution mode. The retention ratio of stationary phase was 51.0%. According to the antioxidant activity assays, phaseoloidin, entadamide A, and entadamide A-β-Dglucopyranoside had certain scavenging abilities on 1,1-diphenyl-2-picrylhydrazyl free radicals and hydroxyl free radicals.
