Objective: To investigate stability of Ganoderma spores oil experienced by six months accelerated test. Method: Taking acid value

peroxide value

contents of total triterpenoids and glycerol trioleate as indexes

quality changes of spores oil after 0

6 months accelerated test were investigated.The content of glycerol trioleate was determined by HPLC

which was performed on a Kromasil C18analytical column with mobile phase of acetonitrile-isopropanol (53:47) at flow rate of 0.5 mL·min-1

column temperature was 30℃

detector was evaporative light-scattering. Result: Compared with zero month

after 6 months accelerated test of Ganoderma spores oil

acid value showed a rising trend with rising 32.11%-39.27%;peroxide value showed a decreasing trend with decreasing 41.17%-46.67%;the content of total triterpenoids showed a decreasing trend with the range of 6.72%-8.13%;the content of glycerol trioleate showed a decreasing trend with dropping by 3.78%-4.54%;acid and peroxide values were accorded with gienic standard for edible vegetable oil during 6 months accelerated test. Conclusion: Quality of Ganoderma spores oil remains stable after 6 months accelerated test.
