                       SANGUI BIOTECH INTERNATIONAL, INC.
                             A Colorado corporation
                    CERTIFICATION OF CHIEF EXECUTIVE OFFICER
                            Section 302 Certification

I, Prof.Dr.Dr. Wolfgang K. Barnikol certify that:

1.   I have  reviewed  this  annual  report on Form  10-KSB  Of  Sangui  Biotech
     International, Inc., a Colorado corporation (the "registrant");

2.   Based on my  knowledge,  this  annual  report  does not  contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this annual report;

3.   Based on my knowledge,  the  financial  statements,  and other  information
     included in this annual report, fairly present in all material respects the
     financial condition, results of operations and cash flows of the registrant
     as of, and for, the periods presented in this annual report;

4.   I am responsible for establishing and maintaining  disclosure  controls and
     procedures  (as defined in Exchange Act Rules  13a-15(e) and 15d-15(e)) and
     internal control over financial reporting (as defined in Exchange Act Rules
     13a-15(f) and 15d-15(f)) for the registrant and we have:

     a)  Designed  such  disclosure  controls  and  procedures,  or caused  such
     disclosure controls and procedures to be designed under my supervision,  to
     ensure that material information relating to the registrant,  including its
     consolidated  subsidiaries,  is made  known to me by  others  within  those
     entities,  particularly  during the period in which this  annual  report is
     being prepared;

     b) Evaluated the effectiveness of the registrant's  disclosure controls and
     procedures  and presented in this annual report our  conclusions  about the
     effectiveness of the disclosure  controls and procedures,  as of the end of
     the period covered by this report based on such evaluation; and

     c) Disclosed in this annual report any change in the registrant's  internal
     control over financial reporting that occurred during the registrant's most
     recent fiscal quarter (the  registrant's  fourth fiscal quarter in the case
     of annual report) that has materially affected,  or is reasonably likely to
     materially affect, the Company's internal control over financial reporting;
     and

5.   I have disclosed,  based on my most recent  evaluation of internal  control
     over  financial  reporting,  to the  registrant's  auditors  and the  audit
     committee of the registrant's board of directors (or persons performing the
     equivalent function):

     a) All significant  deficiencies  and material  weaknesses in the design or
     operation of internal control over financial reporting which are reasonably
     likely to adversely  affect the  registrant's  ability to record,  process,
     summarize and report financial information; and

     b) Any fraud,  whether or not material,  that involves  management or other
     employees who have a  significant role in the registrant's internal control
     over financial reporting.
