      Development of a high performance thin layer chromatography method for the rapid qualification and quantification of phenolic compounds and abscisic acid in honeys
      N. STANEK, P. KAFARSKI, Izabela JASICKA-MISIAK* (*Faculty of Chemistry, Opole University, Opole, Poland; izajm@uni.opole.pl)

      J Chromatogr A, 1598, 209-215 (2019). Samples were methanolic extracts of honeys from Robinia pseudoacacia (Fabaceae) or from Tilia spp. (Tiliaceae / Malvaceae), as well as standards: abscisic acid (sesquiterpenoid), caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid (phenolic acids), chrysin (flavone), myricetin, quercetin (flavonols), naringenin (flavanone). HPTLC on silica gel with chloroform – ethyl acetate – formic acid 5:4:1. Visualization under UV 254 nm and 366 nm, before and after derivatization by spraying with aluminium chloride (1 % in methanol), which rendered flavone bands bright yellow. Quantitative absorbance measuremet by densitometry at 366 nm. Linearity was in the range of 12,5–200 µg/mL for most standards (25–400 µg/mL for chrysin). Main differences observed in samples: 1) abscisic acid (hRF 56) and chrysin (hRF 82) were present only in Tilia honey samples, quercetin (hRF 55) only in Robinia honey; 2) ferulic acid (hRF 60) was the most prominent blue band in Tilia honey samples (1.35–18.73 g/kg of honey), and less intense in Robinia honey (0–1.24 g/kg of honey). Multivariate analysis was performed in two different ways with principal component analysis.

      Study of a method for rapid identification of non-benzodiazepine compounds illegally added in health food by TLC (Chinese)
      F. LIN (Lin Fengping)*, J. WENG (Weng Jia), H. LI (Li Huimin) (*Huizhou Inst. for Food & Drug Contr., Huizhou 516003, China, 624595713@qq.com)

      Chinese J. Food & Drug 23 (3), 229-232 (2021). Non-benzodiazepines are inhibitors directly acting in the central nervous system, with sedative, anxiolytic and anticonvulsant effects. They are used as third generation sedative-hypnotic drugs to treat insomnia. However, it has been found that they are illegally added to some health foods on the market, which may cause long-term abuse and cause harm to the human body. Therefore, it is necessary to strenghten a rapid screening to detect the illegal addition of non-benzodiazepines to health foods, to improve the efficiency of supervision, and to crack down illegal practices.  TLC of ethyl acetate extracts of health foods adulterated with non-benzodiazepines, on silica gel with dichloromethane - methanol - ethyl acetate 17:2:6. Detection in UV 254 nm, identification by fingerprint comparison with the standards zolpidem, zalepron and zoppilon. Using this method, 65 batches of health food samples obtained from the market were screened, and four of them were suspected of illegal addition of zopiclone. This result is consistent with the analysis using both HPLC-DAD and HPLC-MS, and proved the  TLC method to be simple, fast, accurate, easy to operate, and well suitable for quick screening.

      A. ROHMAN*, T. WIJAYANTI, A. WINDARSIH, S. RIYANTO (*Department of Pharmaceutical Chemistry, Faculty of Pharmacy, Universitas Gadjah Mada, Yogyakarta, Indonesia; abdulkimfar@gmail.com)

      Molecules 25 (17), E3928 (2020). Samples were curcumin (as standard) and methanolic extracts of Curcuma xanthorrhiza and C. aeruginosa (Zingiberaceae) rhizomes, both separately and in mixtures. Separation on TLC silica gel with chloroform – methanol – formic acid 94:3:3. Densitometry of curcumin (hRF 50) in absorption mode at UV 427 nm. This method was validated with curcumin standard for selectivity (vs. demethoxycurcumin hRF 32), linearity range (250 - 450 ng), LOD (21 ng) and LOQ (69 ng), accuracy and precision. Curcumin contents were between 0.74 and 1.23 % in pure C. xanthorrhiza extracts, but decreased when adulterated with C. aeruginosa.
