[Methods] The study was carried out with orthogonal design . Oil-extraction ratio, oil-bearing rate and inclusion rate of ?-CD inclusion compound of NC were used as indexes. [Results] The optimal process for oil extraction was adding 10-fold water in medicinal materials and then soaking for one hour and distilling for 5 hours. The optimal processing conditions for ?-CD inclusion compound of NC were the proportion of ?-CD and volatile oil being 61, the inclusion compound being stirred for 2 hours at 40℃ .
