DETERMINATION OF ROSAVIN AND SALIDROSIDE IN RHIZOME OF 4 DIFFERENT PLANTS FROM RHODIOLA L.

目的 测定具代表性的国产红景天属植物中rosavin和红景天苷的含量。方法 采用高效液相色谱法。结果和结论 测得 5种不同产地玫瑰红景天中rosavin的含量在 0 .0 8%～ 0 .6 %之间 ,红景天苷的含量 0 .2 6 5 %～0 .74 7%之间 ;3种不同产地大花红景天、3种不同产地狭叶红景天和 1种高山红景天样品中均不含rosavin ,红景天苷的含量在 0 .3%～ 1.2

OBJECTIVE To determine the contents of rosavin and salidroside in representative plants of Rhodiola L. from China. METHODS HPLC method was adopted. RESULTS and CONCLUSION The rosavin and salidroside contents in 5 R.rosea samples from different areas are in the range from 0.08% to 0.6% , and 0.265% to 0.747%,respectively;None of the R.crenulata from 3 different areas,the R.Kirilowii from 3 different areas and the R. Sachalinensis from 1 area contain rosavin while salidroside contents in these species are in the range from 0.3% to 1.2% .
