Olcha o‘simligining bargi, mevasi, sopi va danagi elementar tarkibi unduktiv bog‘langan plazmali mass-spektrometriya usuli bilan tadqiq qilindi. Os‘imlikning tadqiq qilingan namunalarida 43 ta makro- va mikroelementlar miqdori aniqlandi. Bargi tarkibida 24908,25 mg/l, sopida 18145,57 mg/l, danagida 16277,86 mg/l va mevasida 13365,99 mg/l miqdorda elementlar aniqlandi. Olchaning bargi, danagi va mevasi tarkibida kaltsiy, sopida esa kaliy eng yuqori miqdorga ega. Makroelementlar umumiy miqdori quyidagi tartibda kamyib boradi: bargida 23125,221 mg/l, sopida 17192,303 mg/l, danagida - 15037,554 mg/l, mevasida 12810,727 mg/l ni tashkil etdi. Makroelementlar miqdori umumiy mineral tarkibga nisbatan danagida 92,84%, mevasida 94,75%, bargida 92,38% va sopida 95,84% ni tashkil etdi. Mikroelementlar orasida Fe, Si, Al, Sr, Mn, B, Ti, Zn va Cu kabi elementlar ko‘proq miqdorga ega. Tadqiq qilingan namunalarda temirni miqdori ancha yuqori bo‘lib, 347,638 mg/l dan 1018,509 mg/l ni tashkil etdi. Toksik elementlar orasida Pb, Hg, Cd va As aniqlangan bo‘lib, ular orasida qo‘rg‘oshin nisbatan yuqori konsentratsiyaga egadir. Barglari va danagida qo‘rg‘oshinning miqdori sopi va mevasiga nisbatan yuqoridir.
