Method for obtaining oleocanthal type secoiridoids and for producing respective pharmaceutical preparations

Secoiridoids of type I and/or II

• wherein
• I:
• R1=H, R2=H or COOCH3, R3=X1
• II:
• R1=H or OH, R3=X1 individually or in any combination thereof,
• the secoiridoids being pegylated with polyethylene glycol (PEG) having an average molecular weight from 200 to 400, at a PEG-to-secoiridoid ratio ranging from 1:1 to 100:1, for the production of pharmaceutical preparations for oral or transdermal administration or injectable solutions or suppositories or tablets produced after drying and compression.
