k) A number of factors
such as the weather (wet conditions are unsuitable), the season (some
compounds accumulate till flowering), time
of the day (avoid mid-day collection), and age of
the plant (plants in declining vigour of a population are avoidable),
etc., are important considerations.
l) Correct botanical
identification, preservation a few dried specimens of plants and drug
samples as vouchers, field notes on the locality, date of collection,
proper labelling of the specimens and drug samples, documentation of all
aspects by colour photographs, are very important scientific procedures, to
be followed.
