The vascular tissue contains 4 to 5 primary xylem strands. Few secondary tissue also developed. '''Stem:''' Beneath the epidermis is a wide zone of parenchymatous cortex which is composed of thin-walled cells with large intercellular spaces. The cells of the pith are thin walled, rounded, more or less isodiametric with distinct air chambers. '''Leaf:''' Shows more or less isobilateral structure. Epidermis shows the presence of striated cuticle and the striations are more prominent in the lower epidermal cells. The epidermal cells have more or less wavy walls and show the presence of glandular trichomes on both surfaces. The smaller glandular trichomes are born upon a slightly conical stalk and the larger ones possess glandular head of 8 cells. In surfaceview, these trichomes are seen as divided into 4 to 8 cells. Upper surface has moretrichomes and less stomata than the lower. A few prismatic crystals of calcium oxalateare found in the mesophyll region and are surrounded by bundle sheath. Midrib is not distinct. A distinct bundle sheath surrounds the vascular bundle of the “midrib”and is represented by a few spiral or annular vessels on the ventral side and phloem on the dorsal side. Anomocytic stomata are found on both surfaces of the leaf.}} {{Macroscopy| source=Natural Remedies Pvt Ltd | companyURL=http://www.naturalremedy.com/ | companyimage=Natural Remedies Logo.png | description='''Powder:''' Shows starch grains, leaf pieces with anisocytic stoma and 8 celled round glandular trichomes.

Optional: Individually dissolve 1 mg each of asiatic acid, madecassic acid, madecassoside, bacopaside, and bacosine in 1 mL of methanol. | | lanes= Lanes, from left to right (Track, Volume, Sample): # 5 μL Bacopaside, bacoside A3, bacosine (with increasing Rf) # 5 μL Madecassoside, asiaticoside, madecassic acid, asiatic acid (with increasing Rf) # 5 μL Bacopa herb 1 # 5 μL Bacopa herb 2 # 5 μL Bacopa herb 3 # 5 μL Bacopa herb 4 # 5 μL Bacopa herb 5 # 5 μL Gotu kola pwd extract USP # 5 μL Gotu kola herb 1 # 5 μL Gotu kola herb 2 | notes=Images presented in this entry are examples and are not intended to be used as a bases for setting specifications for quality control purposes. System suitability test: Bacoside A3: brownish violet zone at Rf ~ 0.48. Asiaticoside: brownish violet zone at Rf ~ 0.30. Identification: Compare result with reference images. The fingerprint of the test solution is similar to that of the corresponding botanical reference sample. Additional weak zones may be present. Under white light the test solution shows a brown zone at the position of reference bacoside A3 and a faint pink zone at the position of reference bacoside at Rf ~ 0.90. In the lower third of the chromatogram there may be several greenish-brown zones. Test for adulteration: No intense zones may be seen between the zone due to bacoside A3 and bacosine (red arrow, Gotu kola herb). | }} =Supplementary Information= =Sources= <references />
