In recent years, various studies and analyses related to cosmetics safety were conducted according to routine tests in Hygienic Standard of Cosmetics (2007), and the eligible rates of tested cosmetics were high. But the other prohibited and limited use components, such as antibiotics were analyzed rarely, and meanwhile some kinds of cosmetic related dermatitis cases appeared dramatically. Several dermatitis, especially contact dermatitis and hormone dependent dermatitis symptoms were not contained in Diagnostic Criteria and Principles of Management of Skin Diseases Induced by Cosmetics-General Guideline, GB 17149.1—1997. So it indicated the standard, GB 17149.1—1997 should be revised and some prohibited and limited use components such as hormone and antibiotic testing should be appended to the safety analysis of cosmetics.

This study aims to establish an HPLC method for simultaneous determination of gastrodin and eight nucleosides and nucleobases components in Gastrodia elata. The separation was carried out on an Agilent Zorbax Bonus-RP (4.6 mm x 250 mm, 5 μm) column with a methanol-(0.04% acetic acid) water solution gradient elution program at a flow rate of 1.0 mL x min(-1). The column temperature was 36 degrees C, and the detection wavelength was 254 nm. The volume of injection was 20 μL. The nine components including gastrodin, cytosine, uracil, cytosine, adenine, thymine, uridine, guanosine and adenosine were well separated. The calibration curve was well linear in the range of 2.04-262.00 mg x L(-1), 0.20-24.67 mg x L(-1), 0.18-23.75 mg x L(-1), 0.20-25.83 mg x L(-1), 0.20-26.67 mg x L(-1), 0.16-20.00 mg x L(-1), 0.22-27.71 mg x L(-1), 0.20-24.29 mg x L(-1), 0.24-30.58 mg x L(-1), respectively, and the correlation coefficient was between 0.998 9-0.999 9. The average recovery of gastrodin and eight nucleosides and nucleobases were 96.4%-99.6%, RSD less than 2.7% (n = 6). The contents of gastrodin in all the seven Tibet cultured Gastrodia elata samples were over 2 mg x g(-1). Further, all samples contain higher contents of adenosine, guanosine, uridine and cytidine compared to low contents of cytosine, uracil, adenine and thymine. The established method is accurate, reproducible and suitable for the determination of gastrodin and eight nucleosides and nucleobases comppnents in Gastrodia elata.
