類胡蘿卜素是自然界中分布*廣的色素，顏色從黃色到紅色不等，由植物和光合微生物合成。類胡蘿卜素是從四萜 （C40） 中提取的 40 種碳高度不飽和烴，分為兩類：**類是胡蘿卜素，僅含有碳和氫原子（例如α-胡蘿卜素、β-胡蘿卜素、γ-胡蘿卜素、八氫番茄紅素和番茄紅素），**組是葉黃素，其分子結(jié)構(gòu)中含有碳、氫和氧。已鑒定出1000多種類胡蘿卜素。

只有植物、藻類和某些種類的真菌和細(xì)菌才能合成必須在動(dòng)物飲食中提供的類胡蘿卜素，因?yàn)樗鼈兪羌棺祫?dòng)物健康和發(fā)育的重要物質(zhì)。類胡蘿卜素被認(rèn)為可以降低疾病風(fēng)險(xiǎn)，尤其是心血管疾病、某些癌癥和眼部疾病。在這方面研究*多的類胡蘿卜素是蝦青素、角黃素、葉黃素、玉米黃質(zhì)、β-胡蘿卜素和番茄紅素。類胡蘿卜素的有益作用是由于它們通過(guò)與自由基（包括單線態(tài)氧和過(guò)氧自由基）反應(yīng)而發(fā)揮抗氧化劑的作用。

類胡蘿卜素因其無(wú)處不在、功能不同、性質(zhì)特殊等特點(diǎn)，是化學(xué)、生物化學(xué)、生物學(xué)、醫(yī)學(xué)、物理學(xué)等跨學(xué)科研究的主題。對(duì)食品和生物樣品中的類胡蘿卜素進(jìn)行有效定量是必要的。

可根據(jù)要求提供大量類胡蘿卜素，包括各種（Z）-異構(gòu)體、類胡蘿卜素、立體異構(gòu)體和酯類。

>>用于分析目的的高標(biāo)準(zhǔn)類胡蘿卜素

類胡蘿卜素是通過(guò)從天然來(lái)源提取或通過(guò)化學(xué)合成制備的。樣品在密封的安瓿瓶中，在氮?dú)庀绿峁?，以確保穩(wěn)定性。通常，純度（HPLC，%面積）≥95%。

只要有可能，它們就以結(jié)晶形式供應(yīng)，但（E/Z）-八氫番茄紅素和（E/Z）-六氫番茄紅素除外，它們?cè)诃h(huán)境溫度下是油狀的。所有化合物均經(jīng)過(guò)充分表征，分析數(shù)據(jù)（HPLC、紫外/可見(jiàn)光譜）作為數(shù)據(jù)表，以及**數(shù)據(jù)表（SDS或MSDS）隨樣品一起提供。
