Abstract/ Executive Summary:

The study was conducted to determine the saponin content of different local plant sources for using as herbal feed additives for ruminant animals. Six plant sources potential to be used as herbal feed additive were tested for their saponin content and proximate composition. These were fruit pericarp of Sapindus mukorossi, seed kernel of Camelia sinensis, whole fruit of Acacia concinna and Barringtinia acutangula, leaves and drumstick of Moringa oleifera. Collected samples were dried in hot air oven in 60⁰C, ground and stored in desicator for saponin determination. Highest saponin content was determined in the drumstick of Moringa oleifera (24.5%) followed by whole fruit of Acacia concinna (20.3%), leaves of Moringa oleifera (14.6%), fruit pericarp of Sapindus mukorossi (10.0%), whole fruits of Barrintonia acutangula (2.4%) and seed kernel of Camelia sinensis (1.1%).

Objectives:

To determine the saponin content of different local plant sources for using as herbal feed additives for ruminant animals

Methodology:

Six plant sources potential to be used as herbal feed additive were tested for their saponin content and proximate composition. These were fruit pericarp of Sapindus mukorossi, seed kernel of Camelia sinensis, whole fruit of Acacia concinna and Barringtinia accutangula, leaves and drumstick of Moringa oleifera. Sapindus mukorossi and Acacia concinna fruits are widely used in hair care product manufacturing industry and are available in local market from where these samples were collected. Camelia seeds were collected from Lackatoora Tea Estate of National Tea Company Ltd., Sylhet. These seeds were rejected from germination test by the tea estate and were collected in moderately good condition. Moringa leaves and drumsticks were collected from different trees of BLRI campus. All these samples were subjected to proximate analysis. A portion of each sample was dried in hot air oven in 60⁰C, ground and stored in desiccator for saponin determination. Saponin content of those herbal sources was determined Five gram dried, ground and defatted sample dry matter was extracted with methanol for 10 hours in soxhlet apparatus. Saponin was then extracted by butanol in a separating funnel (250 ml). Then the sulotion was concentrated in rotary vacuum evaporator. It was then dissolved in methyl alcohol and added drop wise to di-ethyl ether. Precipitate of saponin was found and filtrated through Whatman filter paper No. 1. Finally it was dried in freeze dryer and saponin was measured gravimetrically.
