      New hirsutinolide-type sesquiterpenoids from Vernonia cinerea inhibit nitric oxide production in LPS-stimulated RAW264.7 cells
      Li-Ming YANG KUO, Pei-Yi TSENG, Yu-Chi LIN, Chia-Ching LIAW, Li-Jie ZHANG, Keng-Chang TSAI, Zhi-Hu LIN, Hsiu-O HO*, Yao-Haur KUO (*School of Pharmacy, Taipei Medical University, Taipei, Taiwan;

      Planta Med. 84(18), 1348-1354 (2018). A subfraction (obtained through liquid-liquid partition and column chromatography) of the ethanolic extract of whole Vernonia cinerea plants (Asteraceae, subf. Cichorioideae) was further fractioned by reverse-phase SPE (solid-phase extraction) followed by preparative TLC on silica gel layer (eluent not given). For verification, zones were detected by spraying with anisaldehyde solution with 10 % sulfuric acid, followed by heating at 100 °C. Further purification by reverse-phase HPLC allowed the isolation of 6 hirsutinolide-type sesquiterpenoids (all with a oxacyclonane forming an ether bridge), including vernolides A and B.

      J. Liq. Chromatogr. Relat. Technol. 42, 249-257 (2019). HPTLC of methanolic extracts from the leaves of Paulownia tomentosa on silica gel with chloroform - ethyl acetate - methanol 20:3:2. HPTLC-direct bioautography by dipping into B. subtilis cell suspension, followed by incubation at 28 °C for 2 h. Then the bioautograms were dipped into an aqueous solution of the MTT vital dye (1 mg/mL (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide), followed by incubation at 28 °C for 30 min. Further analysis by using a HPLC-DAD-MS system allowed the identification of apigenin and p-coumaric acid as highly abundant antibacterial components.
