text: Yo, check it out, listen up, I got something to say,
  A new LC-MS/MS method, comin' your way.
  Analyzing ginsenosides in Panax ginseng RMs,
  Optimized extraction, gettin' them gems.
  
  Using methanol-water, under basic conditions,
  Recovering neutral and malonyl-ginsenosides with precision.
  Optimized mass fragmentation, transitions on lock,
  MRM detection, electrospray, nothin' to mock.
  
  Negative and positive ion mode, we switchin' it up,
  Doin' it big, ain't nothin' stoppin' this stuff.
  Quantitatin' ginsenosides, Rb1 to Rg1,
  Rhizomes, extracts, oral dosage, we ain't done.
  
  Four-methylestradiol, internal standard in the mix,
  Calibration standards, SRM 3389, we fix.
  Mass fraction values, they ain't no joke,
  From 1.27 mg/g to 21.42 mg/g, we go for broke.
  
  SRM 3384, 3385, RM 8664, holdin' it down,
  Ginsenosides range, from high to low, no frown.
  3.25 mg/g to 35.81 mg/g, and 0.56 mg/g to 2.51 mg/g,
  We got the numbers, we got the swag.
  
  So there you have it, the method's complete,
  Analyzin' ginsenosides, nothin' but heat.
  Liquid chromatography and mass spectrometry,
  Revolutionizin' the game, that's our destiny.
