🍆 Medicinal Solanum

Important medicinal Solanum species, solasodine value, and cultivation considerations.

Medicinal Solanum is cultivated for steroidal glyco-alkaloids in berries, especially solasodine used as an intermediate in steroid drug synthesis.


Crop Importance and Species

Solanum viarum / S. khasianum are the principal medicinal types for industrial alkaloid extraction.

The target molecule is solasodine, a precursor for synthesis of several steroidal compounds.


Climate and Soil

The crop is hardy and adaptable under diverse tropical/subtropical conditions.

Field preference:

  • Well-drained red lateritic to loamy soils.
  • Avoid prolonged waterlogging.

Varieties and Propagation

Named selections include less-spiny and improved lines such as Arka Sanjeevini and Arka Mahima.

Propagation is mainly through seed nursery and transplanting.


Field Management

  • Well-prepared field with FYM.
  • Row and plant spacing adjusted to local recommendation.
  • Split NPK application.
  • Early-stage weeding and interculture.
  • Need-based irrigation.

Pests, Diseases, and Berry Harvest

Potential issues include caterpillars, fruit borers, wilt/rot complexes, and leaf diseases under stress conditions.

Harvest note:

  • Alkaloid concentration peaks around physiological maturity of berries (green-yellow transition stage).
  • Berries are sun-dried to required moisture for trade.
