Embodiment 1
[0026] Embodiment 1, extracting the total sesquiterpene lactones of Magnolia magnolia leaves as raw material
[0027] Wash the collected fresh Mangosteen leaf samples and dry them in a dry and ventilated place for 14 days to obtain dried leaves, crush them; weigh 10.0g of crushed dried leaves, add 100mL85% ethanol to a 250mL small beaker, extract them by ultrasonic wave at room temperature for 30min, and pour them out Supernatant; extract the sample twice again with the same method, filter the sample after the third ultrasonic extraction, and combine the three ultrasonic extractions. Wash the filter residue three times with 30mL85% ethanol solution, combine the washing liquid and the extract, and concentrate the filtrate to 50mL by vacuum distillation; The extract of the ester layer is distilled under reduced pressure to obtain the extract, which is the crude extract. The above operation was repeated 10 times, and the extracts were combined to obtain 4.953 g of crude extract....
Embodiment 2
[0032] Example 2. Extracting total sesquiterpene lactones rich in parthenolide from the bark of Magnolia hainanensis as raw material
[0033] Wash the collected fresh mangosteen bark samples and dry them in a dry and ventilated place for 10 days to obtain dry products, crush them; weigh 10.0 g of the crushed dry products, add 80 mL of 90% methanol to a 250 mL small beaker, and extract them by ultrasonic waves at room temperature for 40 minutes, then pour them out Supernatant; the same method was used to extract the sample three times, and after the fourth ultrasonic extraction, the sample was filtered, and the four ultrasonic extractions were combined. Wash the filter residue three times with 30 mL of 90% methanol solution, combine the washing liquid and the extract, and concentrate the filtrate to 60 mL by vacuum distillation; extract the concentrate three times with 180 mL of methyl acetate, and combine three times of methyl acetate The extract of the ester layer was distill...
Embodiment 3
[0036] Example 3: Extracting the total sesquiterpene lactones of Magnolia magnolia hainanensis with stems as raw materials and purifying the active ingredients
[0037] Carry out ultrasonic extraction with the method in Example 1 with 1000g dried stems of Magnolia hainanensis to obtain 59.7849g of extract (crude extract), dissolve the extract with ethanol and mix the sample with 30-60 mesh silica gel, pass 200-300 Mesh, 80×100cm dry silica gel column, eluted with 10:1 petroleum ether and ethyl acetate solution until the color becomes lighter, then eluted with 3:1 petroleum ether and ethyl acetate solution to combine eluent, HPLC tracking Detection, collect fractions containing parthenolide and distill to dryness under reduced pressure, dissolve with as little methanol as possible, pass through 80×100cm C 18 Reverse-phase silica gel column, eluted with 4:6 methanol water solution until the color becomes light, and then eluted with 7:3 methanol water solution elution system, HPL...
