Background : Senna tora L. is an herbaceous annual foetid herb. There were many components s uch as emodine, chrysophanol, aloe-emodine, physcion, rhein, chrysophanic acid, obtusin, aurantio-obtusin, anthraquinone compounds. The seeds and leaves are used to treat skin disease and its see ds can be utilized as a laxative, as well as to good for the eyes. This experiment was focused on the storage characteristics for searching better condition. That's why it is very useful for making oriental medicine. It is needed for Good Agricultural Practices (GAP) certification. It is one of ce rtification condition. Many medicinal plants have almost no their storage condition for GAP.
Methods and Results : There are two kinds of treatment for storage test. One is temperature. The other is time period. The temperature treatments are room temperature and 4℃. Time of storage periods are four parts. The first time period for storage is zero month. The Second is until three month. and the third is until six month. The fourth is until nine month. We used polyethylene for packing materials. We investigated moisture, ash, bacteria, Escherichia coli, Staphylococcus aureus, mold and chromaticity by them. The value of moisture and ash are under standard of permission as 7.8 and 5.1 respectively. There were almost no significance about test microorganism in the storage temperature condition. There were statistical significance on the bacteria and mold without Escherichia coli, Staphylococcus aureus according to storage period. In terms of stroage temperature and period interaction, there was statistical significance on the Escherichia coli. In addition, the mycotoxin (aflatoxin) was analyzed for nine month storage Senna tora L. The total aflatoxin value were 3.307 ppb and 3.334 ppb in storage temperature and period respectively
Conclusion : About the characteristics of Senna tora L. in accordance with the storage treatments, there were differences along with time period of storage about the bacteria and mold. There was no aflatoxin until nine month storage.
