Silica gel 60 f254

Some ingredients were purchased from commercial sources unless otherwise specified. All solvents and liquid reagents were dried by standard methods in advance and distilled before use. All fungi were obtained from the Institute of Pesticide and Crop Protection, Sichuan University. ¹H NMR spectra were recorded in DMSO-d₆ solution on a Bruker 400 MHz (Bruker Corporation, Billerica, MA, USA), using tetramethylsilane (TMS) as an internal standard, and chemical shift values (δ) were given in parts per million (ppm). The following abbreviations were used to designate chemical shift multiplicities: s = singlet, d = doublet, t = triplet, q = quartet, and m = multiple. Thin-layer chromatography (TLC) was performed on silica gel 60 F254 (Qingdao Marine Chemical Ltd., Qingdao, China). Column chromatography (CC) purification was performed over silica gel (200–300 mesh, Qingdao Marine Chemical Ltd.). MS data were obtained using a MALDI-TOF/TOF mass spectrometer (Shimadzu Corporation, Kyoto, Japan). Scanning electron microscopy was performed using a SU3500 Hitachi (Hitachi Group, Tokyo, Japan)

Chemicals and solvents were purchased from commercial suppliers in China and were used without further purification. Solvents and reagents were abbreviated as follows: Menthol (CH₃OH), chloroform (CHCl₃), petroleum ether, dichloromethane (DCM), ethyl acetate (EtOAc), and sodium sulfate (Na₂SO₄). All fungi were obtained from the School of Agricultural, Yangtze University (CN). The melting points were determined on a WRR melting point apparatus (Shanghai Jingke Industrial Co. Ltd., Shanghai, China) and modified. Thin-layer chromatography (TLC) was performed on silica gel 60 F254 (Qingdao Marine Chemical Ltd., Qingdao, China). Column chromatography (CC) was performed over silica gel (200–300 mesh, Qingdao Marine Chemical Ltd., Qingdao, China). ¹H and ¹³C-NMR spectrum were recorded in CDCl₃ or DMSO-d₆ solution on a Bruker 400 MHz spectrometer (Bruker Co., Fällanden, Switzerland), using tetramethyl silane (TMS) as an internal standard, and chemical shift values (δ) are given in parts per million (ppm). The following abbreviations were used to designate chemical shift multiplicities: s = singlet, d = doublet, t = triplet, q = quartet, m = multiple. MS data were obtained using an APEX IV Fourier-Transform Mass Spectrometry (Bruker Daltonics, Billerica, MA, USA).

All chemicals and solvents were obtained from commercial suppliers and were used without further purification. The melting points were determined on a WRR melting point apparatus (Shanghai Jingke Industrial Co. Ltd., PR China) and were uncorrected. Thin-layer chromatography (TLC) was performed on silica gel 60 F254 (Qingdao Marine Chemical Ltd., P. R. China). Column chromatography (CC) purification was performed over silica gel (200–300 mesh, Qingdao Marine Chemical Ltd.). ¹H NMR spectrum were recorded in CDCl₃ solution on a Bruker 600 MHz spectrometer (Bruker Co., Switzerland), using tetramethylsilane (TMS) as an internal standard, and chemical shift values (δ) were given in parts per million (ppm). The following abbreviations were used to designate chemical shift multiplicities: s = singlet, d = doublet, t = triplet, q = quartet, m = multiple. MS data were obtained using a APEX IV Fourier-transform mass spectrometry (Bruker).
