| titleOfInvention | Discriminating method for heroin origins |
| abstract | The invention provides a discriminating method for heroin origins based on neutral or acidic impurities and partial least-squares discriminant analysis (PLS-DA), which is suitable for discriminating affiliation of heroin in two origins: southeast Asia and southwest Asia. The method comprises the following steps: firstly, putting forward a discriminating function of PLS-DA of the heroin origins; detecting peak area numerical values of independent variables of 25 neutral or acidic impurities in a heroin sample, and substituting the peak area numerical values into the PLS-DA discriminating function; calculating the numerical value t of the obtained discriminating function; when t is greater than 0 and less than 6, judging that the heroin origin is southeast Asia; and when t is greater than -6 and less than 0, judging that the heroin origin is southwest Asia. |
