  1. 1.

    By employing the Tillmans-Harris technique, the ascorbic acid content of a number of indigenous plant materials has been determined.

  2. 2.

    Capsicum frutescens, chilli, approachesCapsicum annuum in its ascorbic acid content:

  3. 3.

    Among the citrus fruits tried, theSautgur orange, a special variety ofCitrus aurantium and the pumelo (both the albedo and juice) are rich sources of ascorbic acid.

  4. 4.

    The leaves ofSesbania grandiflora and the leaves and pods ofMoringa pterygosperma possesses about 2 mg. of ascorbic acid per g. of the fresh material. The absence of interfering substances in these materials, especially in the latter, suggests the possibility of their use for the preparation of ascorbic acid and as a standard for titrating indicator solutions.

  5. 5.

    The Indian gooseberry gives the highest reducing value among the materials tried. The presence, therein, of reducing substances other than ascorbic acid is, however, indicated.

  6. 6.

    Juices of the Indian gooseberry and the cashew apple exhibit great stability suggesting the existence in them of a mechanism protecting ascorbic acid from oxidation.

  7. 7.

    Ascorbic acid content of other plant materials are tabulated.
