Microscopic identification
Cross section of leaf
Rhododendron
The main veins also protrude from both sides of the leaf. Epidermis cells above and below the main vein are much larger than the epidermal cells of the mesophyll. They are square and thick in the stratum corneum. The upper surface of the epidermis has 1 to 3 columns of thick horny cells and the lower epidermis. There are 5 to 7 columns of thick-cornered cells and parenchyma inward. The vascular bundle is of a tough type with a crescent-shaped xylem and a narrow phloem. The mesophyll cells of the mesophyll are rectangular, and the cross-section of the stomata can be seen in the lower epidermis. The palisade tissue is not obvious. The calcium oxalate cluster crystals are sometimes seen in spongy and parenchyma cells, and the diameter is 16-26 μm.
2. Ordinary Moringa
The main difference from the above species is that the leaf thickness is about 2 times that of the above species, the main vein protrudes significantly downwards, and only slightly uplifts toward the surface of the leaf. The upper and lower epidermal cells of the main vein are rectangular and the stratum corneum is thick. The species is large and has a diameter of 20 to 57 μm.
Stem cross section
1. Cross-section of R. edulis (diameter 1.5mm)
Round in shape, with 1 to 3 edges. Epidermal cells are nearly square, and the stratum corneum is thin. The outermost layer of the cortex is 2 to 3 columns of thick-angle cells. The cells contain chloroplasts, with 6 to 8 rows of parenchyma cells often containing starch. Grain, single-grained, round, umbilical and lamellar lines are not obvious, diameter 3 ~ 7μm; endothelial cells are more obvious, oblong, and even in a circle. The phloem is narrow; the layers form a loop; the xylem is connected in a circle, and the medullary line consists of 1 to 2 cells. The pith was larger and the edge parenchyma cells were slightly woody. Individual parenchyma tissues contained calcium oxalate clusters with diameters ranging from 25 to 33 μm. 2. The cross-section of R. edulis (diameter 1.7mm) is very similar to that of the above species. The parenchyma cells contain starch grains, and the single-layered, round, umbilical point stratified veins are also not obvious, larger and 6 to 17 μm in diameter. Calcium oxalate clusters are also large, with a diameter of 33 to 50 μm.
TLC
Sample preparation: Take 1 g each of coarse powder, add 15 ml of ethanol, immerse in water bath for 20 minutes, filter, filter the water bath to dry, add ethanol to 1 ml, and spot after dissolving. Isogeneic bear fruit is the reference substance.
