Composite peony seed oil self-emulsifying system composition and preparation method thereof

The invention provides a composite peony seed oil self-emulsifying system composition and a preparation method thereof. The self-emulsifying system composition comprises composite peony seed oil, emulsifier and co-emulsifier, can further contain dispersant and/or solid adsorbent and can be prepared into oral formulations like soft capsules, liquid capsules, hard capsules and granules. The self-emulsifying system composition after entering a body can self-microemulsify under action of gastrointestinal liquid to form emulsified liquid, and absorption of the self-emulsifying system composition in a gastrointestinal tract can be promoted, so that bioavailability and efficacy of the composite peony seed oil self-emulsifying system composition are improved. The self-emulsifying system composition is low in cost, high in stability, convenient to store and transport and little in side effect, and compliance of a patient with oral formulation medicine based on the composite peony seed oil self-emulsifying system compo
