V raziskavi so bili preučevani učinki različnih koncentracij spermina (Spm) in putrescina (Put) kot elicitorjev na tvorbo kapsaicina v različnih časovnih intervalih v suspenzijski celični kulturi paprike (Capsicum annuum ‘Kahramanmaraş Hat-187’. Kalus je bil pridobljen iz izsečkov hipokotila kalic paprike, ki je vzkalila v in vitro razmerah, celične suspenzije so bile pripravljene iz kalusov. Spm (0,1; 0,2 in 0,4 mg l-1) in Put (0,1; 0,2 in 0,4 mg l-1) sta bila dodajana kor elicitorja v celične suspenzije, hkrati so bile vzpostavljene kontrolne celične kulture brez elicitorjev. Količina kapsaicina v celicah je bila večja v kontrolnih skupinah in vzorcih tretiranih celic z elicitorjem Spm kot pa v filtratu. Največje povečanje kapsaicina v celicah je bilo določeno po 12 dneh elicitacije z dodatkom 0,2 mg l-1 Spm. Največja količina kapsaicina v filtratu je bila določena osmi dan pri dodajanju 0,1 mg l-1 Spm. Najbolj učinkovita koncentracija Put, 0,2 mg l-1, za tvorbo kapsaicina je bila 12 dni po dodajanju, v celicah kot v filtratu. Največja celokupna vsebnost kapsaicina, 312,747 ± 8.70 µg g-1kulture, je bila določena pri dodajanju 0,2 mg l-1 Spm na dvanajsti dan. Zaključimo lahko, da je dodajanje Spm in Put kot elicitorjev vplivalo na  akumulacijo kapsaicina.
