Can I ask you some questions? 1. What is the extraction process and crude ectract process? includes the solvents and methods. 2. what is the purification process? 3. What types of adsorbent you are using? What is the suitable adsorbent for purificanion of phenolic compounds in mangosteen? 4. What is the mobile phase you are using? and the sequence of solvent being used? 5. What is the physical indicator to justify that elution proces is completed? 6. Im your opinion, what is the suitable type of elution solvent commonly used ? 7. normally, eluants are in mass or volume form?\ Hope to hear from you soon. Thank you for you attention. you can directly reply to my e-mail icexxm@hotmail.com. I’m very interested in your HPLC analysis of xanthone in mangosteen. Can I ask you some questions?

Now after your review I might have to next time I go. I’ve seen this fruit in market when I was in Thailand but never got around to try it. Now after your review I might have to next time I go.
