Embodiment 1
[0039] Embodiment 1: Get 5 kg of leaves of Euphorbiaceae Phyllostachys chinensis, grind into below 100 orders, extract 3 times with ethanol with a volume concentration of 50%, filter, merge the filtrate, reclaim ethanol, obtain ethanol extract, obtain extractum, After silica gel column chromatography, gradient elution with chloroform-methanol volume ratio (100:0-95:5), collect the eluted part with chloroform-methanol volume ratio (95:5), detect with TCL, and collect the Fractions of A were combined and concentrated to obtain crude crystals of cinnamonin A. The crude crystals were prepared by preparative RP-HPLC (chromatographic column: C-18 column; volume ratio: mobile phase: acetonitrile: water = 22:78; detection wavelength: 255nm; flow rate: 5mL / min), and collected Glycoside A component, and each collected eluent was detected by HPLC (chromatographic column: C-18 column; mobile phase (volume ratio): acetonitrile:0.2% phosphoric acid solution=28:72; detection wavelength: 255n...
Embodiment 2
[0040] Embodiment 2: Get 5 kg of leaves of Euphorbiaceae Phytophthora barbatus, grind them into less than 100 orders, extract 4 times with 60% ethanol, filter, merge the filtrate, reclaim ethanol, obtain ethanol extract, obtain medicinal extract, pass through silica gel Column chromatography, gradient elution with chloroform-methanol (100:0~90:10), collect the eluted part with a volume ratio of chloroform-methanol (90:10), detect with TCL, collect the fraction containing cinnamonin A , combined and concentrated to obtain crude crystals of cinnamonin A. The crude crystals were prepared by preparative RP-HPLC (chromatographic column: C-18 column; volume ratio: mobile phase: acetonitrile: water = 20:80; detection wavelength: 255nm; flow rate: 5mL / min), and collected Glycoside A component, and each collected eluent was detected by HPLC (chromatographic column: C-18 column; volume ratio: mobile phase: acetonitrile: 0.2% phosphoric acid solution = 30:70; detection wavelength: 255nm;...
Embodiment 3
[0041] Embodiment 3: Get 5 kg of leaves of Euphorbiaceae Phyllostachys chinensis, grind them into less than 100 orders, extract 5 times with 80% ethanol, filter, merge the filtrate, reclaim ethanol, obtain ethanol extract, obtain medicinal extract, pass through silica gel Column chromatography, gradient elution with chloroform-methanol (100:0~85:15), collect the volume ratio: chloroform-methanol (85:15) eluted part, detect with TCL, collect the stream containing cinnamonin A Separated, combined, and concentrated to obtain crude crystals of cinnamonin A. The crude crystals were prepared by preparative RP-HPLC (column: C-18 column; volume ratio: mobile phase: acetonitrile: water = 25:75; detection wavelength: 255nm; flow rate: 5mL / min), and collected Glycoside A component, and each collected eluent was detected by HPLC (chromatographic column: C-18 column; mobile phase: acetonitrile: 0.2% phosphoric acid solution = 40: 60; detection wavelength: 255nm; flow rate: 1mL / min) combi...
