Embodiment Construction

[0120] The following examples further describe the separation and preparation of Philinopside E.

[0121] Choose 60kg of fresh square-column pentagonal ginseng grown in the sea area of ​​Zhanjiang, Guangdong Province, China, wash and remove the internal organs, and then air-dry naturally. The dried body wall is taken, pulverized, soaked and extracted with 5 times the amount (weight) of 85% ethanol at room temperature for 7 days. Filter out the ethanol extract, recover the ethanol under reduced pressure, and then extract it several times with n-butanol (50 L), and extract the n-butanol extract with petroleum ether (5 L), chloroform (5 L) and diethyl ether (5 L) successively to obtain a stream. extract. The liquid extract was dissolved in 3 times the weight of water, filtered, and the filtrate was passed through a D101 macroporous resin column, and eluted with water and 80% ethanol in turn. The 80% ethanol eluate was collected, and the solvent was recovered under reduced press...
