The evaluation of Oryza sativa L (Black rice) extracts for detection of spermatozoa on the clothing and vaginal swab samples

A sexual assault forensic examination performs both presumptive and confirmatory test on semen evidence from either cloth or vaginal swab of the victim. The presumptive test usually an acid phosphatase (AP) test causes curious results, false-negative results from degradation or false-positive results from vaginal fluid [1]. The positive detection of spermatozoa is therefore a crucial step in determining the investigation strategy for laboratory analysis in sexual assault cases [2,3]. Positive areas are excised for DNA analysis and further personal identification.
