Salviae Miltiorrhizae Radix et Rhizoma consists of the dried roots and rhizome of
Salvia miltiorrhiza Bge. (Fam. Labiatae). It contains NLT 0.2 % of tanshinones and
NLT 5.0 % of salvianolic acid B, both calculated on the dried basis.

Tailing factor: NMT 2.0 for the tanshinone ⅡA peak, Standard solution
Relative standard deviation: NMT 2.0%, determined from tanshinone ⅡA peak in
repeated injections, Standard solution

这里面的NLT和NMT是什么意思？谢谢各位~ 返回小木虫查看更多
