Gas chromatography – mass spectroscopic analysis of stem of achras sapota.

This study was carried out to analyze the active constituents present in the stem of Achras sapota (Sapotaceae). Seventeen compounds in ethanolic extract were identified by Gas Chromatography – Mass Spectrometry (GC-MS) analysis.n-Hexadecanoic acid (27.03 %), Benzoic acid, 3-hydroxy-(20.89%), 9, 12, 15-Octadecatrienoic acid, (Z, Z, Z)-(9.71%) and 2-Furancarboxaldehyde, 5-(hydroxymethyl)-(8.55%) were the major constituents of ethanolic extract. This is the first report of identification of active constituents from the stem of Achras sapota by GC-MS.

Effect of ethrel treatment on the postharvest changes in the turnover of ascorbic acid and reducing sugar in Achras sapota fruits.

There was a definite relationship between growth and ascorbic acid content in Achras sapota. Increase in ethrel concentration from 250 ppm to 500 ppm hastened early ripening and increased the amount of reducing sugars but depleted the ascorbic acid content. Other aspects of ascorbic acid turnover viz. ascorbigen, bound form of ascorbic acid, ascorbic acid utilization, net ascorbic acid bound and ascorbic acid oxidase were also studied.
