      A multivariate analysis on the comparison of raw notoginseng (Sanqi) and its granule products by thin-layer chromatography and ultra-performance liquid chromatography
      X. ZHOU, V. RAZMOVSKI-NAUMOVSKI, K. CHAN* (National Institute of Complementary Medicine, University of Western Sydney, Penrith, and Faculty of Pharmacy, The University of Sydney, Sydney, Australia; *k.chan@uws.edu.au)

      Chinese Medicine 10, 13 (2015). Samples were root and rhizome extracts of Panax notoginseng (Araliaceae), either raw or in the form of commercial granules. Standards were ginsenosides Rg1, Rb1, Rd, Re and Rg2, notoginsenoside NR1. TLC on silica gel with chloroform – ethyl acetate – methanol – water 15:40:22:9, followed by 10 min air drying. Derivatization for ginsenosides by immersion into sulfuric acid (10 % in ice cold methanol), followed by 10 min air drying and 5 min heating at 100 °C. Quantification by densitometric fluorescence measurement (deuterium and tungstene lamp, 366 nm). For each standard the linear range was 0.05-1 mg/mL (LOQ comprised between 38 and 431 µg/µL). As NR1 and Re (ratio ca. 2:1) had almost the same hRF, they were quantified together as one substance. Multivariate analysis through hierarchical (HCA) and principal component analyses (PCA) was used to order the samples into two clusters, according to the analyte concentrations, the raw plant extracts being richer than most of the commercial products. This TLC method was compared to quantification through UPLC-PDA (Ultra-performance liquid chromatography with photo diode array), which was more sensitive (LOQ between 10 and 49 µg/µL) but did not allow the separation between Rg1 and Re (ratio ca. 6:1).

HPTLC on silica gel (pre-washed with methanol and heated 30 min at 100 °C) with n-hexane – ethyl acetate – acetic acid 15:9:1. Derivatization by immersion: A) into anisaldehyde – sulfuric acid reagent, followed by 10 min heating at 105 °C, for the detection of steroids and terpenes; B) into DPPH• (0.2 % in methanol), followed by 30 min incubation in the dark, for the detection of antioxydants; C) into Fast Blue B solution (0.1 % in 70 % ethanol) for detection of phenols (with alkylresorcinols detected as dark purple zones on colorless background). Effect-directed analyses were performed directly on the plates. D) α-Amylase inhibition assay by immersion into enzyme solution, incubation 30 min at 37 °C, immersion into substrate solution (starch 2 % in water), incubation 20 min at 37 °C and immersion into Gram’s iodine solution for detection (inhibition zones appear blue on white background). E) Acetylcholinesterase (AChE) inhibition assay (after neutralization by immersion into phosphate buffer) by immersion into enzyme solution, incubation 30 min at 37 °C, immersion into substrate solution (α-naphthyl acetate) and into dye reagent (Fast Blue Salt B). Densitometry through automated scanning, quantification expressed as equivalents to the respective standards used for calibration curves: A) β-sitosterol (LOQ 1.6 µg/band), B) gallic acid (LOQ 60 ng/band), D) acarbose (LOQ 173 µg/band), E) donepezil (LOQ 96 µg/mL).
