The correlation between biochemical properties and protein content were also observed. Five different extraction conditions were applied where the optimum conditions for highest yield and purity were ‘H<sub>2</sub>SO<sub>4</sub>-(NH<sub>4</sub>)<sub>2</sub>SO<sub>4 </sub>buffer /pH 1.5 /80 °C /1h /<em>Amrapali</em>’ and ‘Tem. 99.8 °C/ HCl-NaOH buffer/ pH1.5/ 1h/ <em>Amrapali</em>’ respectively. The best source among four varieties was <em>Langra</em> as it contained highest purity (AUA, 72.27±0.03%) under a specific condition.  The best extractant was HCl-NaOH buffer as the pectin extracting with it contained minimum impurity (3.10±0.06). This study also showed that pectin from <em>Amrapali</em> contained both Low and High Methoxyl pectin with the same extraction condition other than extractant. The proximate, elementary, microbiological, spectroscopical and structural investigations were also conducted in this study.</p><p><em>Bangladesh J. Sci. Ind.
