Abstract

Ljekovita svojstva poput antioksidativnih, protuupalnih i antiseptičkih proizlaze iz bogatog nutritivnog sastava kurkume (Curcuma longa L.) i mača zelenog čaja (Camellia sinensis). Sadržaj makro- i mikroelemenata u uzorcima kurkume i mače određen je metodom atomske emisijske spektrometrije uz induktivno spregnutu plazmu (ICP-AES) i spektrometrijom masa uz induktivno spregnutu plazmu (ICP-MS). Svi uzorci su razoreni u uređaju za mikrovalno potpomognuto razaranje smjesom dušične kiseline i vodikovog peroksida. Nakon optimiranja metode za pripravu uzorka, metodama ICP-AES i ICP-MS određen sadržaj elemenata: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Rb, Se, Sr, Te, Tl, V i Zn. Sadržaj makro- i mikroelemenata razlikuje se u različitim uzorcima iste biljne vrste te između kurkume i mača zelenog čaja.

Abstract (english)

Properties such as antioxidant, anti-inflammatory and antiseptic derive from the rich nutritional composition of curmuma (Curcuma longa L.) and matcha green tea (Camellia sinensis). The content of macro- and microelements of curcuma and matcha green tea was determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The samples were digested using nitric acid and hydrogen peroxide in a microwave assisted digestion system. After optimizing the sample preparation method, the element content was determined by ICP-AES and ICP-MS methods: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Rb, Se, Sr, Te, Tl, V and Zn. The content of macro- and microelements differs within the same plant species and within turmeric and matcha green tea.
