Moulding Process of Total Flavonoids Capsule from Lithocarpus litseifolius

Objective:To investigate moulding process of total flavonoids capsule from Lithocarpus litseifolius.Method:The moulding process of total flavonoids capsule from L.Litseifolius was selected with angle of repose,moisture absorption rate,critical relative humidity(CRH),and bulk densityas indexes.Result:The optimum process was as follows:silica gel as excipient and its dosage was 10%,0# vacant capsule was used,CRH was 66%.These conditions could meet the requirements of capsules filled.Conclusion:The moulding process is rational and practicable.
