- Abstract
- To investigate the oxidative stability of the Lithospermum erythrorhizon extracted oil, we prepared extracted oil from the cultivated and wild roots of Lithospermum erythrorhizon by autoclave method with soybean oil. The oil were stored for 30 days at 60℃, and the peroxide value (POV), acid value (AV) and carbonyl value (CV) were measured periodically. The weight was highly decreased in the oil added roots of Lithospermum erythrorhizon during the storage period. POV of soybean oil containing wild and cultivated Lithospermum erythrorhizon was generally enhanced with prolonged storage time, with the POV of the samples being lower than 100 meq/kg.oil after 30 days of storage. However, the POV of soybean oil was higher than 100 meq/kg.oil after 10 days of storage. The pattern of the changes of AV and CV of soybean oil containing wild and cultivated Lithospermum erythrorhizon, were almost constant during the experimental periods. Nevertheless, the pattern of the changes of AV of soybean oil was rapidly increased during 20 days of storage, and that of CV of soybean oil was rapidly increased duringdays of storage and then slowly increased during the remainder of the experimental period. However, soybean oil was rapidly increased during 20 days of storage and then slowly decreased during the reminder of the experimental period. The overall results suggest that wild and cultivated Lithospermum erythrorhizon added antioxidant activities to the autooxidation of soybean oil.
