A study on investigation of the chemical constituents & milled wood lignin analysis of lantana camara & prosopis chinnsis.

ABSTRACT

Investigation was carried out on Lantana Camara & Prosopis Chinensis, the plants of verbenacea ( vervain) & leguminosae (Mimosaceae) family for studying their chemical constituents by isolation of milled wood lignin of Lantana Camara & Prosopis Chinensis through different isolation techniques such as hydrolysis & solvent extractions.This has indicated that the lignin prepared from wood species Lantana Camara contains carbon 56. 2%, hydrogen 5.80% ,oxygen 36.00% and methoxy groups 19.70%. Prosopis Chinensis contains carbon 60.70%, hydrogen 6.30%, oxygen 33.00% and methoxy groups 19.78%. The C9 formula weight for Prosopis Chinensis & Lantana Camara is 204.82 & 212.99 respectively. The other reactive groups of lignin of Lantana Camara & Prosopis Chinensis investigated were also comparable with the other non wood species.
