一、原料与分类区别

传统茶：茶树的芽叶，绿茶、红茶、乌龙茶、白茶、黄茶、黑茶六大类代用茶：非茶树植物的叶、花、果实、根茎等，菊花茶、玫瑰花茶、枸杞茶、荷叶茶、桑叶茶、决明子茶等二、成分与功效差异传统茶含有2%–5%的咖fei因、10%–30%的茶多酚、1%–2%的茶氨酸，具有提神、抗氧化、助消化等功能。功效相对有限，且存在饮用禁忌，如空腹、睡前不宜饮用，体虚胃寒者慎饮绿茶。代用茶不含或含极低咖fei因，适合对咖fei因敏感人群或晚间饮用。多由草本、花果搭配而成，部分具备清热、助眠安神、促进代谢等辅助调理作用，如菊花清肝明目、玫瑰舒缓情绪、荷叶利湿消肿。三、中科溯源实验室可通过化验咖fei碱、茶多酚、茶氨酸含量判断是否为真茶。利用红外光谱（FTIR）和核磁共振（NMR）辅助判断植物来源真伪。采用电感耦合等离子体质谱法（ICP-MS）测试铅、镉、砷、汞等重金属含量；气相色谱-质谱联用（GC-MS）：用于挥发性成分如芳香油、挥发油的定性定量分析，适用于陈皮、薄荷类代用茶。液相色谱（HPLC）：测定非挥发性活性成分，如黄酮类（芦丁、槲皮素）、多酚、皂苷等，常用于菊花、枸杞、决明子等成分分析。LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;min-height:auto;max-height:none;min-width:auto;max-width:none;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransPARency="true" scrolling="no" allow="attribution-reporting; run-ad-auction" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&lmt=1773108987&plaf=1%3A2&plat=1%3A128%2C2%3A128%2C3%3A2097152%2C4%3A2097152%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C41%3A32%2C42%3A32%2C43%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&pra=5&aiof=9&asro=0&itsi=40&aiapm=0.1542&aiapmd=0.1423&aiapmi=0.16&aiapmid=1&aiact=0.0001&aiactd=0.0001&aicct=0.0001&aicctd=0.0001&ailct=0.0001&ailctd=0.0001&aimart=4&aimartd=4&aieuf=1&aicrs=1&uach=WyJXaW5kb3dzIiwiMTAuMC4wIiwieDg2IiwiIiwiMTMyLjAuNjgwNS4wIixudWxsLDAsbnVsbCwiNjQiLFtbIk5vdCBBKEJyYW5kIiwiOC4wLjAuMCJdLFsiQ2hyb21pdW0iLCIxMzIuMC42ODA1LjAiXSxbIkdvb2dsZSBDaHJvbWUiLCIxMzIuMC42ODA1LjAiXV0sMF0.&abgtt=6&dt=1773108987478&bpp=2&bdt=23&idt=29&shv=r20260306&mjsv=m202603050101&ptt=9&saldr=aa&cookie=ID%3Dacc2c446473bb643%3AT%3D1772673265%3ART%3D1773108986%3AS%3DALNI_MYqsQAIIN6bsplgK4vxuWr23y_1HQ&gpic=UID%3D00001213a3a461be%3AT%3D1772673265%3ART%3D1773108986%3AS%3DALNI_MbUhm5wiqeaPQ4fEwdCXatTGekkVA&eo_id_str=ID%3Dd3617a85dc743122%3AT%3D1772673265%3ART%3D1773108986%3AS%3DAA-AfjaoE9soFBL0RbzDphxDYHgJ&nras=1&correlator=8795472503801&frm=23&ife=1&pv=2&nhd=1&u_tz=480&u_his=13&u_h=720&u_w=1280&u_ah=680&u_aw=1280&u_cd=24&u_sd=1.5&DMC=8&adx=-12245933&ady=-12245933&biw=1263&bih=582&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31096885%2C95378429%2C95381340%2C95383701%2C95384193%2C95385044%2C42533294%2C95381976%2C95384716%2C95382195%2C95379824&oid=2&pvsid=1143239041331238&tmod=1338073581&uas=0&nvt=1&fsapi=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&fc=1664&brdim=0%2C0%2C0%2C0%2C1280%2C0%2C1280%2C680%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&bz=1&ifi=1&uci=1.84ywq4fzl5yv&fsb=1&dtd=42" data-google-container-id="1.84ywq4fzl5yv" tabindex="0" title="Advertisement" aria-label="Advertisement" data-load-complete="true">
