An approach developed to standardise commercially available complex Ayurvedic drugs with particular
reference to the application of both classical and
instrumental analytical techniques is presented.
Navaratna and Buddharaja Kalkas were studied
and the monographs giving standards in terms of identity,
quality and purity were compiled for their 34 raw
materials. Standard samples of the two kalkas were
prepared, the preparative methodologies were discussed
and the standards fJr the two compound preparations
were specified. Umbelliferone was identified as a
marker compound to establish the presence of asafoetida
in Navaratna Kalkaya. Use of GLC profiles to establish the presence or absence of the other ingredients
in Navaratna Kalkaya was discussed.
Finally the results obtained for the two
standard samples were compared with those of commercial products.
