目的 對金果欖Tinospora sagittata外觀性狀與其主要化學(xué)成分間的相關(guān)性進(jìn)行研究，探究“辨狀論質(zhì)”理論在金果欖藥材鑒別中的科學(xué)性。方法 觀察并測量金果欖的形狀、顏色等9種性狀指標(biāo)；采用HPLC法檢測40批次金果欖中木蘭花堿、蛻皮激素、非洲防己堿、藥根堿、巴馬汀和古倫賓含量；比較金果欖的9種外觀性狀指標(biāo)、6種化學(xué)成分之間的聯(lián)系，并對金果欖“狀-質(zhì)”數(shù)據(jù)進(jìn)行相關(guān)性分析和回歸分析。結(jié)果 金果欖藥材的皺縮程度、藥材長寬比、表面顏色、斷面顏色、L*、a*值各與6種主要化學(xué)成分含量具有顯著相關(guān)性，而b*值與除蛻皮激素外的5種化學(xué)成分均呈極顯著相關(guān)。結(jié)論 金果欖藥材表面皺縮程度、表面顏色、斷面顏色、短徑、長寬比、質(zhì)量以及L*、a*、b*值均可用于快速判斷金果欖藥材的品質(zhì)，其中b*值最為關(guān)鍵且全面，結(jié)果可為快速全面評價金果欖藥材的質(zhì)量提供參考。

Objective To study the correlation between the appearance of Jinguolan (Tinosporae Radix) and its main chemical constituents, and to investigate the scientific validity of the theory of “quality evaluation through morphological identification” in the identification of Tinosporae Radix. Methods Observing and measuring nine kinds of trait indexes, including shape and colour of Tinosporae Radix; useding high performance liquid chromatography (HPLC) to detect the contents of magnolflorine, hydroxyecdysone, columbamine, jatrorrhizine, palmatine and columbin in 40 batches of Tinosporae Radix; comparing the association between the nine kinds of appearance trait indexes and the six kinds of chemical compounds in Tinosporae Radix and making a correlation analysis and regression analysis of the Tinosporae Radix “shape-quality” data.Results The degree of crumpling, herb aspect ratio, surface colour, section colour, L* and a* values of Tinosporae Radix were each significantly correlated with the content of six major chemical constituents, whereas the b* values were highly significantly correlated with all five chemical constituents except hydroxyecdysone. Conclusion The surface crumpling degree, surface colour, section colour, short diameter, aspect ratio, weight and L*, a*, b* values can be used to quickly determine the quality of Tinosporae Radix, among which the b* value is the most critical and comprehensive, and the results of this study can provide a reference for the rapid and comprehensive evaluation of the quality of Tinosporae Radix.
