Abstract:
1. A method for producing a purified shark cartilage extract with anti-parathyroid hypertensive factor activity, comprising the steps of: extracting cleaned, dried, ground shark cartilage with H cooling the resulting suspension to between 40-60° C., centrifuging the cooled suspension at between 5200-5700 rpm to separate the suspension into supernatant 1 and pellet, holding the supernatant 1 in a cooling tank at 4-8° C., extracting the pellet a second time with H cooling the resulting suspension to between 40-60° C., centrifuging the cooled suspension at between 5200 to 5700 rpm to separate the suspension into supernatant 2 and pellet, pooling supernatant 1 with supernatant 2, and spray drying the pooled supernatants to obtain the shark cartilage extract.
