VARIATIONS IN THE RESIN CONTENT OF VARIOUS PARTS OF PODOPHYLLUM EMODI L

1 The various parts such as roots, rhizome, stem, petiole and leaves of the flowering and non‐flowering plants of Podophyllum emodi were collected separately during April, July and September, 1951, from the Kashmir Point Forests Murree Hills, Punjab, and were analysed for their total resin contents after drying them at a temperature of about 41° C. 2 The various parts of the plant were found to have maximum resin percentage during spring, which period is thus most suitable for collection of the drug. 3 The leaves were found to contain between 7·83 to 9·7 per cent, of resin and should also be employed as a rource of resin. 4 The age does not seem to have any significant effect on the resin content, as can be seen from the comparison of resin percentages in different parts of the flowering and non‐flowering plants.
