1). The raphe is 500–800 μm thick. The cells of the raphe are small compact thick walled liquefied and compact. The tracheid bar is spindle shaped with conical ends. It is made up
of narrow tracheids which are compactly arranged (Fig. 1). It is 600 μm Ibrutinib clinical trial in height and 250 μm thickness. The palisade zone consists of two layers of narrow compact thick walled cells. The cells are liquefied and darkly stained. The spongy parenchyma cells are small blue color and loosely arranged. The palisade zone is 150 μm thick. It extends as seed coat on the lateral part of the seed. The seed coat (Fig. 2) is 250 μm thick. It consists of a thin superficial cuticle narrow, compact, cylindrical or columnar layer of palisade tissues. The cells are columnar or macrosclereids with thick liquefied walls and a narrow lumen. The palisade or columnar layer is 100–120 μm thick. Inner to the palisade layer is a layer of osteosclereids in which the cells are bone shaped with narrow middle part and dilated ends resembling the bones. The osteosclereids MK-1775 layer is 100 μm thick. Inner to the osteosclereids a zone of 3 or 4 layers of thin walled compact parenchyma cells were seen. The inner most part is a thick darkly stained layer of thick walled endodermis. The outer epidermal layer of the cotyledon
consists of small darkly stained cells. The cells become gradually wider and compact. The inner epidermal cells are small with prominent cuticle (Fig. 3 and Fig. 4). Cells are densely filled with starch. The seed powder consists of the following components which can detect under the microscope. Large globular or elliptical starch grains are major constituent of the powder. When viewed under microscope the grains appear bright with central hilum. The starch grains are simple type and no compound grains are evident (Fig. 5). The starch much grains are 20 μm in diameter. Spherical cells are abundant in the powder (Fig. 7). The cells contain darkly stained granular inclusions. The cells are thin walled and are 50 × 100 μm
in size. Two types of sclereids are seen in the powder osteosclereids and macrosclereids or columnar sclereids (Fig. 6, Fig. 8 and Fig. 9). These are bone shaped cells with narrow central region and dilated ends. They occur attached to the outer seed coat in a horizontal line (Fig. 9). Their walls are fairly thick and liquefied. They are 100 μm in height (Fig. 8 and Fig. 9). These cells are narrow long pencil like cells with thick liquefied walls and narrow lumen. The cells are uniform in thickness. They are seen as separate individual cells as well as in thick compact layer. The macrosclereids are 150 μm long and 10 μm thick. The phytochemical screening of MMC and EMC revealed the presence of alkaloids, phenols, flavonoids, amino acids, quinones, steroids and carbohydrate. The results of antimicrobial activity of MMC and EMC are furnished in Table 1.
