Abstract

Objectives : In order to develop effective and safe anti-oxidation, the effects of Menthae Herba (M. spicata L. and M piperita L.) were examined. Methods : M. spicata L. and M. piperita L. of Menthae Herba were used to make water extracts and methanol extracts, and then its anti-oxidative effects were compared in vitro. Results : 1. M. spicata L. was stronger than M. piperita L. in anti-oxidative effects of methanol extracts, and water extracts showed similar anti-oxidation effects. 2. Water extracts of M. spicata L. was stronger than M. piperita L. showed a stronger superoxide anit-oxidation than the same-density ascorbic acid, so that water extracts were proved to be stronger than methanol extracts. 3. Methanol extracts' DPPH anti-oxidation was similar in M. spicata L. and M piperita L.. As for water extracts, M. spicata L. showed higher anti-oxidation and M. piperita L. had no anti-oxidation. 4. As for anti-oxidation of LDL and linoleic acid of methanol extracts, both M. spicata L. and M. piperita L. were stronger than a-tocopherol. As for the water extracts, these two showed similar level of anti-oxidative effect on linoleic acid, which is weaker that mehtanol extracts. 5. M. spicata L. includes more phenol than M. piperita L. Conclusions : Menthae Herba (M. piperita L. M. spicata L.) had anti-oxidation effect, so that it can be medically developed for anti-oxidation.
