-    Isolation and chemical structural elucidation of 3–4 compounds from water extract of Coffea arabica leaves.
-    200g products (CAFETASO) supporting treatment of the renal calculus from leaves of Coffea arabica and set up basic standards of CAFETASO products.
- Determining contents of several heavy metals (Lead/Pb; Mercury/Hg, ..) and the median lethal dose LD₅₀ of product CAFETASO.
- Set up fingerprint LC/MS method for quick determining of major compounds in the samples of leaves of Coffea arabica.
-    1-2 papers  in Scientific Conference or Scientific Trade Journal.

-    Eleven compounds were isolated from Coffea arabica leaves and chemical structures of 9 compounds among them were  elucidated. Three compounds including caffeine, 3β-hydroxylup-12-ene-28-oic acid and ursolic acid show good bioactivities (diuretic effect, anti-HIV, anti-cancer ).
-    600g products supporting treatment of renal caculus were manufactured with the basic standards (formation, contents of heavy metals and the median lethal dose (LD₅₀) of product CAFETASO).
-    Contents of several heavy metals (Lead/Pb; Mercury/Hg,...) were determined according to Standards QCVN 8-1:2011/BYT of Vietnamese Health Ministry.
-    The median lethal dose LD₅₀ of product CAFETASO was determined with LD₅₀ ~ 92g drug/kg).
-    Fingerprint LC/MS method was set up successfully for quick determining of major compounds in the samples of leaves of Coffea arabica.
-    01 paper was reported in Proceeding of Scientific Conference of ICH, VAST (2011) and 01 paper was published in Journal of Chemistry of VAST (2012). T.50 (4B). pp. 54-58.

-    First time, the Coffea arabica leaves sample in Vietnam was studied on chemical composition and several remarkable bioactive compounds were isolated such as caffeine, 3β-hydroxylup-12-ene-28-oic acid and ursolic acid.
-    600g products supporting treatment of renal caculus were manufactured with the basic standards (formation, contents of heavy metals and the median lethal dose LD₅₀ of product CAFETASO).
-    Fingerprint LC/MS method was set up successfully for quick determining of major compounds in the samples of leaves of Coffea arabica..

- Material products:
    + 600g products supporting treatment of renal caculus were manufactured with the basic standards (formation/capsule (500mg), contents of heavy metals (lead, mercury, asen,…) and the median lethal dose LD50 (~92g/kg) of product CAFETASO).
    + Summary report

Further studies are required to investigate the potent treating renal calculus patients in large amount with products CAFETASO, the semi-acute toxicity of the products CAFETASO from Coffea arabica leaves. So that, we propose a new project: “Study on technological process of manufucturing funtional foods supporting treatment of renal calculus patients from leaves of Coffea arabica L.)” and please help us executing this suggesting project.
