| Summary: | Abstract: <br />
<br />
<br />
A very bitter white needle crystalline alkaloid has been isolated from the chloroform extract of the fresh stems of Tinospora crispa (L) Miers ex Hook. F. & Thems. It melted at 124 - 125C. <br />
<br />
<br />
The ultraviolet, infrared, nuclear magnetic resonan ce, and mass spectra showed the alkaloid contained an even number of nitrogen atom, aromatic nuclei, -OH phenolic or -NH bounded, Ca,C or C-N, -OCH31 C=0 groups and its molecular weight was 374. <br />
<br />
<br />
From the data obtained it can be deduced that the compound is not berberine or palmatine and neither artefacts resulting from berberine nor palmatine with chloroform. <br />
