ABSTRACT
Bamboos popularly known as green gold is sufficiently cheap and plentiful to meet the vast needs of people. It plays major role in
the livelihood of rural people. Seeds of bamboos are viable hardly for few months so understanding the biochemical metabolites
and its effect with ageing was main aim of research work. The aim of the study was to estimate primary metabolites i.e. sugars,
phenols and amino acids and antioxidant ascorbic acid in Bambusa bambos, Dendrocalmus strictus and Dendrocalamus Hamiltonii
and its effect with ageing under prolonged storage conditions. The highest amount of sugars (7.99 mg/gmfwt), phenols (7.53
mg/gmfwt) and amino acids(7.56 mg/gmfwt) found in Bambusa bambos at 48 hours analysis in 18 months interval and ascorbic acid
content maximum in fresh seeds of Bambusa bambos (3.67 mg/gmfwt ) and its relationship of decrease in metabolites with the loss
of viability with ageing after 18 months period.
Keywords: Primary metabolites, Sugar, Phenols, amino acids, Ascorbic acid.
INTRODUCTION
amboos belongs to the most diverse group pf
plants in the grass family. Bamboos are plants of
global interest because of their distinctive life
form, ecological importance and wide range of uses and
values they have for humans
1
. There are more than 1500
different documented traditional uses of bamboo. In Asia,
Bamboos are the essence of life for many communities
and it is no exaggeration to speak of a Bamboo
Civilization in the region. Bamboos can be propagated
from rhizomes, culm or by multiplication of nursery raised
seedlings. However seeds serve as best material for large
scale plantations and germplasm conservation. But seeds
have a very short viability of 1-2 months and therefore
useful as propagules only for a short period of time. Seed
quality is one of the factor for successful germination but
its trait declines with ageing.
So the present study was aimed at determining the
biochemical primary metabolites in the three species of
bamboo seeds i.e. Bambusa bambos, Dendrocalmus
strictus and Dendrocalamus Hamiltonii and their effect
with ageing after 18 months period and its loss of viability
during storage for such long period. Seed deterioration is
reported to accompany changes in hydrolytic enzymes as
well
2
. It was studied the physiological and biochemical
changes in Abelmoschus esculentes seeds of different
ages and concluded that germination decreases with seed
ageing

MATERIALS AND METHODS
For the quantitative estimation of primary metabolites,
different protocols were used. 10 Seeds of each species
i.e Dendrocalamus strictus, Dendrocalamus hamiltonii
and Bambusa bambos which were stored in controlled
conditions in desiccator at 4 degree Celsius were soaked
and deglumed and weighed. Their homogenate was made
in 10 ml of 80% ethanol using pestle and mortar with a
pinch of acid washed sand. It was then centrifuged at
3000 rpm for 10 minutes at room temperature. The
supernatant was used for the analysis of amino acids,
sugars, total phenols and ascorbic acid.
For Estimation of Free Amino Acids
4
Using glycine as standard. To 0.5 ml of homogenate
added 5 ml of ninhydrin reagent and shaken properly.
Then the mixture was boiled for 10 minutes in water and
cooled thereafter absorbance was recorded at 570 nm on
spectrophotometer.Glycine was taken as standard amino
acid.
For Estimation of Total Sugars
5
To 4 ml of chilled anthrone reagent 0.1 ml of ethanol
extract was added. Tubes were shaken gently to mix the
solution. these were covered with glass marbles and
placed in water bath and cooled in ice water.
The absorbance of the blue green colored solution was
taken at 625 nm in spectrophotometer against blank
containing 80% ethanol extract.
For Estimation of Total Phenols
6
To 1 gm of the seed material was extracted in 5ml of 0.3
N HCl in methanol. Centrifuge it, retain supernatant and
repeat the extraction with residue.
Pooled the two supernatant and evaporate them.
Dissolve the residue in 5 ml distilled water. 0.1 ml of
aliquot in each case was taken to make final volume of 7
ml of distilled water.
