    不知道楼主说的这个麻是不是我说的辣
    液相上有个国标,是测辣椒的
    请问楼主是测什么样品中的麻,具体啥成分,有cas吗

    不是辣素,是花椒素,好像有两个羟基。

    Hydroxy-alpha sanshool is a molecule found in plants from the genus Zanthoxylum. It is believed to be responsible for the numbing and tingling sensation caused by eating food cooked with Sichuan peppercorns.

    The term sanshool in the compound's name is derived from the Japanese term for the Sichuan pepper, sanshō (山椒?) (literally, Mountain Pepper), to which was appended the suffix -ol, indicating an alcohol.
    Mechanism

    Though the chemical structure is similar to that of capsaicin, the mechanism of action by which hydroxy-alpha sanshool induces sensations have been a matter of debate. Although the compound is an agonist at the pain-integrating cation channels TRPV1 and TRPA1 as is capsaicin, newer evidence suggests that the Tandem pore domain potassium channels KCNK3, KCNK9, and KCNK18 are primarily responsible for the molecule's effects.[1]

    Hydroxy-alpha sanshool excites D-hair afferent nerve fibers, a distinct subset of the sensitive light touch receptors in the skin, and targets novel populations of Aβ and C-fiber nerve fibers.[2]

    看结构,液相更好。但感觉气质也可以做,不知道怎样的条件好。

    Hydroxy-alpha sanshool is a bioactive component of plants from the Xanthoxylum genus, including the Sichuan pepper. It is believed to be responsible for the numbing, tingling sensation (paresthesia) caused by eating food cooked with Sichuan peppercorns.
    The molecular mechanisms by which hydroxy-alpha sanshool induces these sensations have been a matter of debate. Although the compound is an agonist at the pain-integrating cation channels TRPV1 and TRPA1, newer evidence suggests that the two-pore domain potassium channels KCNK3, KCNK9, and KCNK18 are primarily responsible for hydroxy-alpha sanshool's effects.[1]
    The term sanshool in the compound's name is derived from the Japanese term for the Sichuan pepper, sanshō (山椒?) (literally, Mountain Pepper), to which was appended the suffix -ol, indicating a chemical alcohol.
