Abstract: Disclosed is a kettle-type continuous production method for glycine. The method includes: performing a hydantoin synthesis and hydrolysis reaction on glycolonitrile, ammonium carbonate, ammonium bicarbonate and water in a reactor with multiple serially connected kettles, and then purifying, concentrating, crystallizing, separating and drying the products to obtain refined glycine. The reactor with multiple serially connected kettles consists of a hydantoin synthesis section and a hydantoin hydrolysis section which are connected in sequence, the hydantoin synthesis section including a first reaction kettle group of reaction kettles with a reaction temperature of 80-100° C. and a second reaction kettle group of reaction kettles with a reaction temperature of 100-120° C.

Abstract: A gynostemma pentaphyllum-containing health care pharmaceutical composition for preventing hyperlipidemia, hypertension, hyperglycemia and gout is prepared by mixing raw materials of gynostemma pentaphyllum, folium eucommiae, folium mori, semen plantaginis, herba lophatheri, pueraria mirifica powder, pelargonium graveolens and sanguisorba minor, and the raw materials are in percentage by mass: 40-70% of gynostemma pentaphyllum, 5-20% of folium eucommiae, 5-20% of folium mori, 5-10% of semen plantaginis, 2-10% of herba lophatheri, 2-10% of pueraria mirifica powder, 2-8% of pelargonium graveolens and 2-8% of sanguisorba minor. The gynostemma pentaphyllum is prepared by mixing diploid gynostemma pentaphyllum leaves and tetraploid gynostemma pentaphyllum leaves according to a ratio.
