Bacopa monnieri (L.) Wettst. (Scrophulariaceae) commonly known as
“brahmi”, has been used in the traditional systems of medicines as "Medhya
Rasayana" as it increases mental clarity and brain stimulating action. It is
also being used as anti-inflammatory, analgesic, antipyretic, sedative,
antioxidant and anti-cancerous agent. The present study was carried out to
provide characteristic anatomical markers for root, stem and leaf, along
with this study preliminary photochemical analysis was also carried out for
the presence of major secondary metabolites which can act as the indicator
of bioactivity of the different plant parts of Bacopa monnieri (L.) Wettst. The
distinguishing features for root and stem are simple starch grains, xylem
vessel with spiral thickenings, pitted tracheids and for leaf are sub-
epidermal foliar idioblast, sessile, multicellular trichome and prismatic
calcium oxalate crystals. Presence of two types of stomata i.e. anomocytic
and diacyitc in the same field of vision under 45X magnification, are seen in
the surface preparation as well as in the powder microscopy of Bacopa
monnieri leaf. This is the major observation of the study. All these
distinguishing features can be used as anatomical markers for correct
indentification of root, stem and leaf of the plant. Preliminary
phytochemical analysis revealed the presence of alkaloids, saponins,
flavonoids, tannins, carbohydrates, proteins and anthroquinones in
different plant parts of Bacopa monnieri while quantitative estimation
showed that alkaloids (mg /g dry weight) in root, stem and leaf were found
to be 1.67 ± 0.577, 47.00 ± 0.81 and 53.07 ± 2.08 respectively; saponins (mg
/g dry weight) in root, stem and leaf were 7.50 ± 0.71, 23.33 ± 1.53 and
57.00 ± 2.65 respectively and flavonoids (mg /g dry weight) in stem and
leaf were 25.33 ± 1.53 and 27.67 ± 2.08 respectively. Thus the findings of
the present study will provide referential pharmaco - botanical information
for correct identification and authentication of the crude drug and its plant
parts.
Keywords: Bacopa monnieri (L.) Wettst., foliar idioblast, anomocytic,
diacytic types of stomata, prismatic calcium oxalate crystal and
phytoconstituents.
