Institute of Pharmacognosis - University of Vienna
Pharmaziezentrum, Althanstraße 14, 1090 Vienna

The Institute of Pharmacognosis focuses on all topics which are important in connection with pharmaceutically active substances derived from plants  - this includes living plants which are being kept in glasshouses and open gardens belonging to the institute as well as in experimental in-vitro propagation.

The Institute of Pharmakognosis operates two fogging systems -

  • for tropical medicinal plants which are being kept in the roof gardens of the University Centre Althanstraße

  • for the so called  "hardening phase" of in-vitro propagated cultures which
    is needed following the extraction from the sterile culture vessels

Roof Garden

On the roof of the Centre for Pharmacy  (stairwell D, level 6), the glasshouse of the institute is located. Some 600 m2 are used for display as well as for cultivation of plants for research and lectures. The display-collection contains drug-, poison and crop plants from tropical and mediterranean areas.

The fogging aggregate feeds seven independent departments of the roof garden which can be provided with microfog according to the current parameter settings.

Details of piping - each department has its own high pressure feed and a relaxation pipe which branch off from two main feeder pipes.
The main feeder pipes run thru all departments where the branchoffs are operated by means of magnetic valves.
Pipes, valves and connectors are made from stainless steel.

In-vitro propagation

The second fogging aggregate is used for precise humidification of transplanted cultures. In a first step plant fragments are being propagated in culture medium, forming after some time small plantlets which are extremely fragile when they are taken out of the medium. In plastic tents the transplanted plantlets are cultivated with high relative humidity to the new environment.

The work group Plant-Biotechnology works with in-vitro-propagation of medicinal plants as well as with in- vitro-production of medicinal substances.
The first point targets plants which are endangered due to over-gathering - with special regards to species from Nepal and India. For intensively collected species like Swertia chirata, Lilium nepalense
or Picrorhiza kurroa micro-propagation protocols are being developed. Following the creation of clone-bases and selection processes large amounts of genetically identical high value seedlings can be produced for the following large scale growing in fields. These selected plants provide a high and consistent content of substances whereby an early standardization of the final product Phytopharmakon is possible. Moreover the selection process can be used to reduce or eliminate toxic substances. In this way the pyrrolizidinalkaloid-free coltsfoot Tussilago farfara "Wien" could be registered EU-wide during 1999.
Works for producing medicinal and natural substances follow not only the classical cell-suspension systems, but mainly with differentiated tissue-types.  Here we work with so called "meristemal clusters" or "nodules", as well as with cultures from roots and shoots; we also work with transgenetic roots, so called "hairy roots".
For all mentioned areas we also work on "scale-up" procedures as well as on automatizing procedures.

Sterile cultures

Hardening tent for plantlets -
each tent is monitored with a precision hygrostat

Distribution manifold of a climate chamber

As the chambers are quite crowded (for energy consumption reasons) all connections are implemented with high pressure hoses so that all positional adjustments can be easily achieved

Central control panel

Two High pressure pumps (one always in standby)

Climate parameters of each tent can be adjusted individually
