Partitioning of 14Co2 Photosynthetic Assimilate Into Primary Metabolites, Roots and Into Total Saponins in Medicinal Herb Chlorophytum Borivillanum

Abstract :

Relationship between14CO2 photosynthetic assimilate partitioning between shoot and root and subsequent utilization of assimilate for saponins accumulation has been reported for the first time in Chlorophytum borivilanum. Time dependent distribution (12, 24 and 36h) showed maximum content of 14C in sugars and amino acids after 24h of feeding in leaves. Maximum translocation of leaf assimilates as sugars and amino acids to roots occur at 36h while organic acids were highest at 12h after feeding. In roots the total saponins content received maximum 14C assimilate up to 36h after feeding indicating that assimilate is biosynthetically utilized. The results of this study suggest that selection of Chlorophytum plants with higher photosynthetic capacity will result in higher saponins content.
