The invention discloses a method for extracting squalene by using camellia oleosa seeds as raw materials and tea oil and squalene soft capsules and relates to the technical field of biomedicine. The extraction method comprises the following process flows of material preparation, grinding, leaching, concentration, methyl esterification, complexant-borax reaction, macroporous resin chromatographic separation and purification, concentration, extraction, washing, concentration, preparation of squalene crude oil and supercritical carbon dioxide extraction, so that squalene essential oil with the squalene content of more than or equal to 80 percent is obtained. The tea oil and squalene soft capsules are prepared from the following raw materials in percentage by weight: 87 to 90 percent of squalene essential oil with the squalene content of more than or equal to 80 percent, 3 to 5 percent of polyethylene glycol 400, 2 to 3 percent of beewax and 2 to 5 percent of phospholipid. The raw material resources are wide. The prepared tea oil and squalene soft capsules not only can be used for medicine, but also can be used for food therapy, are particularly suitable for administration of treatment and food therapy of patients suffering from hepatitis, fatty liver, acute and chronic inflammation, tumor, chemotherapy, diabetes mellitus and cardio-cerebrovascular disease and have no toxic or side effects.
