a. Parenchymatous tissue b. Unicellular trichome c. Calcium oxalate
d. Anomocytic stomata e. Xylem vessels f. Glandular trichome
g. Epidermis h. Oil glands (in flower) i. Spiral vessels (in flower)
Fig.4 (a-i): Showing various characteristic features of flower and leaves of Quisqualis indica
represented in Table 2. In the histochemical analysis the
micro chemical tests showed the presence of midrib, vascular
bundle and xylem vessels.
3.3 Powder analysis
The powder microscopy shows the fragments of
unicellular covering and glandular trichomes, phloem fibers,
parenchyma cells, numerous xylem vessels of spiral type and
Epidermal cells with anomocytic stomata is shown in Fig.4.
3.4 Quantitative microscopy
As a part of quantitative microscopy, stomatal number,
stomatal index, vein islet and vein termination number were
determined by using fresh leaves of the plant (Table 3).

Parameter
Values
Stomatal number 0.28-0.32
Stomatal index 15.12-20.32
Vein islet no. 2-5
Vein termination no. 3-6
Phloem fiber
Length:6.76-78.21
Width :1.06-1.45
Calcium oxalate crystals
Length:1.6-3.2
Width :1.2-1.6
Starch grains 1.56-8.0

3.5 Physical constant
Length:10.62-45.54
Width :1.56-2.56
The physical constant evaluation of the drugs is an
important parameter in detecting adulteration or improper
handling of drugs. The total ash is particularly important in
