Embodiment 1
[0028] Example 1: Preparation of the total xanthone fraction of mangosteen
[0029] Mangosteen peel 3kg, after crushing, add 90% (v / v) ethanol-water 25L to heat and reflux to extract twice, each time for 2 hours, after the combined extracts are filtered through gauze, centrifuged at 1000rpm for 5 minutes, take the supernatant The solution was concentrated, freeze-dried into a dry extract to obtain the mangosteen extract GM (360g). Take 290g of mangosteen extract, dissolve it in an appropriate amount of water, filter, and take the filtrate and subject it to macroporous resin HP-20 open column chromatography, ethanol-water gradient elution. Respectively recover under reduced pressure to obtain water elution fraction (109.0g), 30% (v / v) ethanol-water elution fraction (69.0g), 50% (v / v) ethanol-water elution fraction (16.0g) , and a 90% (v / v) ethanol-water elution fraction (88.0 g). Wherein, the 90% (v / v) ethanol-water eluted part is the GMD of the total xanthone part of mangost...
Embodiment 2
[0030] Example 2: Establishment of HPLC characteristic spectrum of total xanthone parts of mangosteen
[0031] The total xanthone parts of mangosteen obtained in Example 1 were dissolved with an appropriate amount of methanol to make a 5.0 mg / mL solution, and after passing through a 0.45 μm filter membrane, the test solution of the total xanthone parts of mangosteen was obtained.
[0032] Precisely take 10 μ L of the above-mentioned test product, refer to the high-performance liquid phase analysis method specified in the appendix of the National Pharmacopoeia, inject high-performance liquid chromatography for chromatographic analysis, and record the chromatogram ( figure 1 ). The liquid chromatography conditions are as follows: use octadecylsiloxane bonded silica gel as the stationary phase; use methanol-water solution containing 0.1% formic acid as the mobile phase, and gradient elution; the flow rate is 1mL / min; the detection wavelength is 360nm; the chromatographic column ...
Embodiment 3
[0036] Example 3: Investigation on the reproducibility of the HPLC characteristic spectrum of the total xanthone part of mangosteen
[0037] Get four batches of mangosteens purchased from different times (2007-05-05, 2008-05-15) and different origins (Guangdong, Thailand), and process them sequentially according to the preparation method in Example 1 to obtain four batches of total xanthenes of mangosteen Ketone parts (GD2007, TG2007, GD2008, TG2008), according to the processing method and liquid phase conditions in Example 2, carry out HPLC analysis respectively, obtain the HPLC characteristic collection of four batches of total xanthone parts of mangosteen, in which α-inverse The relative retention time of each chromatographic peak and the corresponding chemical substances of each chromatographic peak calculated by the chromatographic retention time of mangostin as 1 are as follows:
[0038] Peak No. 1: 0.57±0.01 (mangosteen alcohol)
[0039] Peak No. 2: 0.66±0.01 (3-isoman...
