Bacteriostasic activity experiments on anthocyanin extracted from Malva sylvestris inhibiting Staphylococcus aureus, Escherichia coli, Aspergillus niger, were conducted by using solid and liquid culture methods. The results showed that the anthocyanin of M. sylvestris had a great bacteriostasic activity to Staphylococcus aureus but had no bacteriostasic activity to both Escherichia coli and Aspergillus niger. The bacteriostasic activity to Staphylococcus aureus increased with increasing content of anthocyanin of Malva Sylvestris in the solid-culture experiment. The average diameters of bacteriostasic circle for Staphylococcus aureus was 6, 13.5, and 16.0 mm at 10g·L−1, 20g·L−1, and 30g·L−1 contents of anthocyanin of M. sylvestris, respectively. Moreover, this bacteriostasic activity kept long time as anthocyanin was of the high concentration.

The effect of seed oil of Korean pine (Pinus koraiensis) on the rats’ blood-fat and its anti-ageing function was studied for appraising the efficacy of the seed oil of Korean pine. Sixty experimental rats were randomly divided into 5 groups (half males and half females in each group) as normal control group, high fat diet control group, and three groups (Group 1 Group 2, Group 3) that were fed with feedstuff with the contents of the seed oil of 2.0g/(kg·d−1), 4.0g/(kg·d−1) and 8.0g/(kg·d−1), respectively. The indexes such as superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and anti-oxidation capacity (AOC) were measured by Reagent Kit method. It was found that the seed oil of the Korean pine could reduce the content of triglyceride and improve SOD as well as GSH-PX activity in serum. These indexes of the rats in Group 2 fed with Korean pine seed oil of 4.0 g/(kg·d−1) reached the significant level and those of rats in Group 3 fed with the seed oil of 8.0 g/(kg·d−1) reached the extremely significant level. The results indicated the seed oil of Korean pine had function of regulating the level of blood-fat and anti-ageing.
