    摘要:
    Esculeoside A(2),一种螺索烷甾体糖苷,是从茄属商品茄子(Solanum lycopersicum)(一种微型番茄的商业菌株)中分离出来的主要成分。在微型,中型和桃太郎番茄以及各种加工过的番茄产品中检查了七叶皂甙A(2)的含量变异性。在绿色的未成熟番茄果实中,番茄红素(1)在C-23和C-27处被氧化,从而在成熟果实中产生七叶皂苷A(2)。此外,在成熟的果实中,七叶皂苷A(2)被部分转化为3β-羟基-5α-pregn-16-en-20-一个3 - O -β-糖四糖苷(6),一种孕烷糖苷。Esculeogenin A(3),鼠藤黄酚2容易被转化为3β,16β-二羟基-5α-pregn-20-one(17)。代谢研究显示,食用番茄后,人类志愿者受试者尿液中雄甾烷衍生物的排泄。Esculeogenin A(3)通过其对酰基辅酶A:胆固醇酰基转移酶(ACAT)的作用抑制巨噬细胞中胆固

    A [(5alpha,22S,23S,25S)-3beta,23,27-trihydroxyspirosolane], a sapogenol of tomato-saponin, esculeoside A, was easily converted into a pregnane derivative, 5alpha-pregn-16-en-3beta-ol-20-one, merely by refluxing with pyridine and water. Its chemical mechanism including air oxidation is here described.
    以前,我们报道了一个有趣的反应,即七叶皂甙元A [(5alpha,22S,23S,25S)-3beta,23,27-trihydroxyspirosolane],一种番茄皂甙的皂甙,七叶皂甙A,很容易转化为孕烷衍生物5alpha -pregn-16-en-3beta-ol-20-one,只需与吡啶和水回流即可。在此描述其包括空气氧化的化学机理。

    Conversion of the spirosolane-type glycoside, esculeoside A, a major component contained in the ripe tomato Lycopersicon esculentum fruits, into a solanocapsine-type sapogenol, esculeogenin B-2, (5α,22S,23R,25S)-22,26-epimino-16β,23-epoxy-3β,23,27-trihydroxycholestane, and esculeogenin B-1, (5α,22R,23S,25S)-22,26-epimino-16β,23-epoxy-3β,23,27-trihydroxycholestane, which are rare naturally occurring compounds was attained by acid hydrolysis with 2 N HCl in dioxane and water (1 : 1).

    Major novel steroidal alkaloid glycosides, named esculeoside A (1) and esculeoside B (2), have been isolated from the pink color-type and the red color-type, respectively, of the ripe tomato fruits of Lycopersicon esculentum MILL. for the first time. The structures of 1 and 2 have been characterized as 3-O-beta-lycotetraosyl (5S,22S,23S,25S)-23-acetoxy-3beta,27-dihydroxyspirosolane 27-O-beta-D-glucopyranoside and 3-O-beta-lycotetraosyl (5S,22S,23R,25S)-22,26-epimino-16beta,23-epoxy-3beta,23,27-trihydroxycholestane 27-O-beta-D-glucopyranoside, respectively.

    Italian canned tomatoes contain the tomato glycosides esculeosides B-1 (1, 0.0052%) and B-2 (2, 0.0068%) without esculeoside A. Herein, the structure of esculeoside B-1 (1) is characterized to be 3-O-β-lycotetraosyl (5S,22R,23S,25S)-22,26-epimino-16β,23-epoxy-3β,23,27-trihydroxycholestane 27-O-β-D-glucopyranoside. We hypothesized that these substances might be derived from esculeoside A when the cans are prepared with treatment in boiling water. To confirm that hypothesis, we refluxed esculeoside A with water for 6.5 h, providing esculeosides B-1 (1) and B-2 (2) in yields of 25.8% and 31.0%, respectively.

    Esculeoside A (2), a spirosolane steroidal glycoside, is a major constituent isolated from Solanum lycopersicum, a commercial strain of mini tomatoes. The content variability of esculeoside A (2) was examined in mini, midi, and Momotaro tomatoes and various processed tomato products. In the green immature tomato fruit, tomatine (1) is oxidized at C-23 and C-27 to produce esculeoside A (2) in the ripe
