Characteristics of triterpene-loaded microemulsions
| Formulation | Size (nm) | PDI | Zeta (mV) | DEE (%)a | DEE (%)b | DLE (%) |
|---|---|---|---|---|---|---|
| TME-1 | 41.13±4.11 | 0.199±0.034 | −13.74±2.75 | 83.92±1.82 | 84.27±3.21 | 4.18±0.57 |
| TME-2 | 47.59±5.55 | 0.156±0.045 | −16.98±1.48 | 79.32±2.19 | 81.76±1.65 | 9.87±0.29 |
Notes: DEE (%)a and DEE (%)b represent the DEE of adlay seed oil and triterpene, respectively; each value represents the mean ± standard deviation (n=3).
Abbreviations: PDI, polydispersity index; DEE, drug encapsulation efficiency; DLE, drug-loading rate; TME, triterpene-loaded microemulsion.
