Embodiment 1
[0027] Screening of Effective Parts from Stems and Branches of Spiraea lanceolata for Anti-rheumatoid Arthritis
[0028] Preparation of Spiraea willow stems and branches extract and isolated parts: 10Kg of Spiraea willows stems and branches, add 60% ethanol to reflux and extract three times, each dosage is 80L, each time for 2 hours, filter, the filtrates are combined, reduce Recover the ethanol under pressure to obtain the extract, add water to dissolve the extract, the dosage is 5L, go through the macroporous adsorption resin column D101 chromatography, fill the macroporous adsorption resin D101 with a volume of 5L, elute with water until the eluate is nearly colorless, collect the eluted liquid, concentrated under reduced pressure, and dried to obtain 475 g of water-eluted parts of Spiraea lanceolata stems and branches; eluted with 20% ethanol until the eluate was nearly colorless, collected the eluent, concentrated under reduced pressure, and dried to obtain Spiraea spiraea...
Embodiment 2
[0037] Determination of (+)-8'-hydroxypinoresin-8'-O-β-d-glucopyranoside, (7R,8S)- Dihydrodehydrobiconiferyl-9'-O-β-d-glucopyranoside, (+)-peariginadin-9-O-β-d-glucopyranoside and (+) - Method for the content of isolacitin-9-O-β-d-xylopyranoside
[0038] Chromatographic conditions and system suitability test
[0039] Octadecylsilane-bonded silica gel is used as filler; acetonitrile is used as mobile phase A, 0.1 phosphoric acid solution is used as mobile phase B, linear gradient elution: 0min (A10%, B90%, volume ratio) → 10min (A10% , B90%, volume ratio) → 30min (A30%, B70%, volume ratio) → 60min (A30%, B70%); flow rate: 1.0mL min -1; The detection wavelength is 280nm. The number of theoretical plates is calculated based on (+)-8'-hydroxypinoresin-8'-O-β-d-glucopyranoside, not less than 6000.
