| titleOfInvention | Preparation method and pharmaceutical application of total stilbene compounds in bletilla striata fibrous roots with antidepressant effect |
| abstract | The invention discloses a preparation method and application of total stilbene compounds in bletilla striata fibrous roots. The method comprises the following steps: (1) extraction: taking bletilla striata fibrous roots, adding 5-20 times of 30-95% ethanol by volume, extracting for 1-3 times for 1-3 hours each time, filtering, and combining filtrates to obtain an extracting solution; (2) preparing a sample loading solution: concentrating under reduced pressure until the concentration is 0.2-0.8 g/ml and using the concentration as a sample solution; (3) and (3) purification: loading the mixture onto macroporous adsorption resin at a rate of 0.3-0.6BV/h, statically adsorbing for 2-5h, sequentially removing impurities with 3-4 BV water and 4-5 BV10% ethanol, eluting with 4-5 BV 70% ethanol, collecting 70% ethanol eluate, and drying under reduced pressure to obtain the total stilbene compounds. The method can improve the economic value of the bletilla striata fibrous roots, change waste into valuable, has good environmental protection value, can relieve the shortage of bletilla striata resources at present, and improves the utilization rate of the bletilla striata resources. |
