hi. why do you consider acetone:water (80:20) as the best solvent for mangosteen periicarp extraction? why is it better than ethanol? we are planning to test the pericarp’s extract against a certain bacteria, how can we purify further the extract? we dont have plans to use chromatography in this experiment. thank you

can you really extract xanthone from the bark of the Mangosteen fruit?

i wanna ask..

how to extract the pericarp of mangosteen?
what kind of solvent must i’m use?a
s i know that the pericarp contain enzyme,what kind of enzyme it is?
what method must i use to extract the pricarp to get the enzyme?
hope do reply me a.s.a.p

My final year project is almost similar with your title here…extraction of xanthone and analyze using GC-MS….not HPLC…i wan to ask u some questions:
!) can it be using GC-MS to analyze xanthone?
2) May i know what is the extraction process and crude ectract process? includes the solvents and methods.
3) what is the m/z ratio of xanthone in MS?
4) The extraction method of xanthone for another fruit is it similar to mangosteen?

I’m very interested in your HPLC analysis of xanthone in mangosteen. 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’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.
