摘要: 下箴刺桐碱是一种吲哚类生物碱,被认为是多种中草药的有效成分之一。彩色豆马勃Pisolithus tinctorius是一种硬皮马勃目的大型真菌,能在菌丝体内积累下箴刺桐碱。下箴刺桐碱具有比较强的天然荧光,但其荧光光谱与色氨酸几乎完全重叠,在用荧光方法筛选下箴刺桐碱高产菌株的过程中,共存的色氨酸会严重干扰下箴刺桐碱的定量。本研究构建一种色氨酸的快速荧光检测方法,运用此方法筛选出的一株彩色豆马勃菌株下箴刺桐碱含量(鲜质量含量)达到3.39 nmol·mg-1

关键词: 彩色豆马勃, 筛选, 下箴刺桐碱, 色氨酸, 荧光检测

Abstract: Hypaphorine is an indole alkaloid identified as one of active constituents in some Chinese medicinal herbs. Pisolithus tinctorius is a Sclerodermatales macro-fungi which accumulate hypaphorine in its hyphae. Hypaphorine’s native fluorescent radiation is strong enough,but tryptophan has almost the same fluorescence wavelength as that of Hypaphorine,which will cause serious interference when the hypaphorine was measured. A quick tryptophan-detective Fluorescent spectrometry method has been completed, and one Pisolithus tinctorius strain containing 3.39 nmol·mg-1 hypaphorine has been screened by using this method.

Key words: Pisolithus tinctorius, screening, hypaphorine, tryptophan, fluorescent detection
