Optical rotations were obtained on a JASCO P-2000 polarimeter (Hachioji, Tokyo). UV spectra (MeOH) were measured on a Hitachi U-2900 double-beam spectrophotometer (Hitachi, Japan). Electron circular dichroic (CD) spectra (MeOH) were measured on a JASCO J-720 spectropolarimeter (Hachioji, Tokyo). NMR spectra were recorded by Bruker AV-400, and AV III-600 (CD3OD, δH 3.30 and δC 49.0 ppm). HPLC-SPE-NMR (600 MHz), composed of an Agilent 1100 liquid chromatograph (Waldbronn, Germany), a Phenomenex Prodigy ODS3 (C-18) 100 Å (250 × 4.6 mm, 5 μm) column, coupled with a diode array detector (DAD, G1315A) and a Knauer K120 HPLC pump (makeup pump), a Prospekt 2 automated solid-phase extraction unit (Spark Holland, Emmen, Holland), containing 192 HySphere resin GP cartridges (10 × 2 mm, 10–12 μm), connecting to a Gilson Liquid Handler 215 automated tube transfer (TT) system (Gilson, Inc., Middleton, WI, USA), and a Bruker AV III-600 spectrometer. HPLC-ESIMS (electrospray ionization mass spectrometry) was performed on an Agilent 1100 series liquid chromatograph, followed by an Esquire 2000 mass spectrometer (Bruker Daltonics, Germany). TLC analysis was carried out on silica gel plates (KG60-F254, Merck).
Esquire 2000 mass spectrometer
Manufactured by Bruker
Sourced in Germany
The Esquire 2000 is a mass spectrometer manufactured by Bruker. It is designed to analyze the molecular composition of various samples by separating and detecting their constituent ions based on their mass-to-charge ratio.

Analysis HPLC was carried out on Waters 510 with Waters 484 detector (waters, USA) using a kromasil C18 column (4.6 × 200 mm, Rainbow). Preparative HPLC was carried out on JASCO PU-2087 with JASCO PU-2075 detector (JASCO, Japan) using a HiQ sil C18 column (10 × 200 mm, YATECH). ESI-MS spectra were recorded on a Bruker esquire 2000 mass spectrometer. NMR spectra (1H-, 13C-NMR, HMBC and NOESY) were measured and recorded on Bruker AVANCE 600 (Bruker, Newark, DE) in DMSO using TMS as internal standard. Infrared (IR) spectra were measured on a Fourier transform infrared spectrometer (IFS-55; Bruker).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
