Abstract
Seeds of Abrus precatorius Linn. (Fabaceae), a poisonous plant drug, is being used
in different Ayurvedic therapeutics, after proper processing (Shodhana) with some specific
media. In Ayurvedic literature, media like Godugdha (cow’s milk), kanji (sour gruel) nimbu
swarasa (Lemon juice) etc. has been reported for processing of Gunja seeds. In the
present study, the Gunja seeds were processed by using Godugdha (cow’s milk) and water as
media and the raw seeds were taken as control. This study reveals certain changes in
different physico-chemical parameters and Rf values in HPTLC of Godugdha shodhita Gunja
seed in comparison to the water Shodhita and Raw Gunja seed. It is observed that the colour
of the media was changed to reddish ting after each shodhana. Changes in every physico
chemical parameters confirm the effect of shodhana on Gunja seed. In HPTLC analysis,
varieties of Rf value were detected in raw and shodhita samples indicating change in the
nature of the shodhita drugs.

Introduction:
Gunja (Abrus precatorius Linn.), a
well-known plant of Ayurveda under
Upavisha group (sub/semi poisonous
group) (1), is being used extensively in
different
formulations
with
great
therapeutic significance and is being
advocated to use, in various diseases like
Indralupta (alopecia), Shotha (edema),
Krimi
(helminthes),
Kustha
(skin
diseases), Kandu (itching), Prameha
(urinary disorders) etc. after proper

samaskar known as shodhana (processing
or purificatory procedure) (2,3,4). The
seeds of Gunja are often used criminally
for killing cattle where the seeds are
powdered and made into a paste, with
which the darts or arrows are dressed (5)
The concept of Shodhana (processing or
purification) in Ayurveda is not only a
process of purification or detoxification
but also a process to enhance the potency
and efficacy of the drug (6).
The Gunja seed contains number of
chemical constituents like alkaloid,
steroid, flavones, triterpenoides, proteins,
amino acids etc., among which an
albumotoxin, abrin (a highly toxic protein)
is considered the main responsible
constituent for the poisonous effect of
Abrus precatorius Linn. With an estimated
human fatal dose of 0.1-1 μg/k (7,8), and it

Sudipta Roy et.al, Shodhana (processing) of Gunja (Abrus precatorius Linn.) Seeds
is reported that boiling renders the seed
harmless (5).
Effect of shodhana on Gunja seeds
with cow,s milk and kanji reveals that the
process of shodhana resulted in depletion
of more toxic alkaloid hypaphorine and
protein abrin(9) and it is also reported that
Gunja seeds after shodhana with
Godugdha shows more significant
antimicrobial activity than the raw Gunja
seeds (10). But reporting of effect on
different other parameters is lacking.
Hence, the present study carried out to
evaluate the impact of shodhana of Gunja
seeds, through Godugdha on physicochemical and HPTLC profile study.
Material and methods:
Collection and selection of drug:
The
plant
Gunja
(Abrus
precatorius L., Fabaceae), was identified
by expert plant taxonomist with help of
different flora and its mature seed (red
variety) were personally collected from
Gunja plants from surrounding place of
Jamnagar, Gujarat in their natural habitat,
during the month of November - January.
The fully matured dry seeds were first
dropped in a beaker containing water. The
seeds those floated on the surface of water
or found broken, fade in colour were
rejected. The seeds, those settled at the
bottom of the beaker were selected for
purification after being dried in air and
were made in to coarse powder with help
of a mechanical grinder and were kept in a
glass jar, considered as Raw Gunja Seeds
(RGS), to be used for all shodhana
purpose.
Equipment for Shodhana (Purification):
Stainless steel vessel (20 cm x 30
cm ) ; capacity of 7 L, used as Dolayantra,
Stainless steel rod (28 cm), Stainless steel
vessel (48 cm x 30 cm x7 cm ) ; capacity
of 3L., Cotton threads 30 cm in length,
Measuring mug (capacity of 1L), Muslin
cloth (45 cm x 45 cm), Digital weighing
machine, Digital induction cooker,
stainless steel spatula (length: 30 cm), and
measuring cylinder (10 ml, 25ml).
Procedure:
In this study, Shodhana of Gunja
seeds (Coarse powder) were carried out by
one of the classically approved methods
(1). Each Shodhana procedure was
repeated for three times to establish the
validation
of
the
pharmaceutical
processing. Shodhana of Gunja was
performed by the process of Swedana
(boiling) in Godugdha (12). 100 g of Raw
Gunja seeds (RGS) were kept in a muslin
cloth and made into a pottali. The pottali
was hanged in a steel vessel and freshly
collected Godugdha was filled in the
vessel, up to the complete immersion of
the pottali as per standard Swedana
procedure (11). Boiled on an induction
cooker, for six hours at 1000C, throughout
the experiments. Total 7 litres of
Godugdha was utilized for one batch
throughout the process. After boiling for
six hours, the seeds were taken out from
pottali and washed with lukewarm water
followed by removal of seed coat and kept
on a glass plate, for the shade drying. After
proper drying, the seeds were collected
and stored in air tight glass container and
being labeled as ‘Godugdha shodhita
Gunja seed’ (GSGS).
Same procedure was followed for the
Shodhana of Gunja seed with Water
(obtained from RO plant) and the final
product was labeled as Water shodhita
Gunja seed (WSGS).
Preparation of sample:
The Raw (RGS) and shodhita
Gunja (Both GSGS & WSGS) seeds were
powdered with mechanical grinder and
passed though mesh no. 60.
Physico chemical parameters:

as foreign matter, moisture content, ash

Results and Discussion
During Shodhana of Gunja with
Godugdha and water, change in the color
of both the media, from its normal colour
to reddish ting, was noticed and it might be
due to the removal of color containing
materials from the endosperm of the seeds.
The reddish cream colour powder of raw
seeds turned into brownish color in case of
Godugdha shodhita Gunja seed and Ash
colour in case of water shodhita Gunja
seed after shodhana (Table-1). After
shodhan with Godugdha and water,
85.96% and 91.66% of purified Gunja
seed were obtained respectively.[Table-2]
It might be due to the extraction of more
soluble mass from the seeds by Godugdha
than water.
It was observed that the moisture
content of Godugdha shodhita Gunja seed
was comparatively lower than the raw and
water shodhita Gunja seed [Table-3].
Determination of moisture content of drug
is one of the important methods in plant
standardization. Excess of moisture in a
sample may encourage growth of
microbes. Lower value of moisture content
indicates less chances of microbial growth
(11). Ash value was decreased in case of
all samples after purification. Ash mainly
contains inorganic radicles and it should
be totally free from carbon particles.
Lower the carbon particle in ash reduces
the ash value which indicates more purity
of a drug. The water soluble extractive
value in Godugdha shodhita Gunja seed
was found higher than raw water shodhita
Gunja seed. It is being observed that all
samples are acidic [Table-3]. Lower the PH
value indicates more acidic in nature,
which is more capable to inhibit microbes.
In HPTLC, at short UV 254nm,
different spots were found in all three
samples indicating presence of different

components. [Table-4] Presence of one
common Rf value (0.01) in all three
samples, indicates the presence of one
common component to all three samples.
At long UV 366 nm, raw Gunja
seed, Godugdha shodhita Gunja seed and
water shodhita Gunja seed showed 6, 5
and 5 spots respectively. [Table-5] From
the below mentioned spectral comparison
(Fig-9, Fig-10, Fig-11) some same Rf
value were found in case of all three
samples i.e. 0.32, 0.48 & 0.96. From
which it can be narrated that the presence
of same component is possible in case of
all three samples.

Conclusion:
From this study, it is concluded
that shodhana alters the physicochemical
parameters of Gunja seeds and also the Rf
value of the sample in HPTLC. Numbers
of spots were decreased under both 254nm
and 366nm after shodhana, indicating
denaturation of some component after
shodhana.
