Study on the Pharmacognosy of S. Spatuliforius

Sauropus spatulifolius Beille (S. spatulifolius) is the dried plant of the genus Sauropus, and belongs to the family Euphorbiaceae. To study the pharmacognosy of Sauropus spatulifolius Beille (S. spatulifolius). A preliminary analysis in terms of primal identification, macroscopic identification and chemistry was carried out on S. spatulifolius. The transverse section of S. spatulifolius roots and stem showed that the cambium was obvious and the xylem was well developed; the transverse section of roots shows that the phloem appeared narrow and the vascular bundle was collateral. The transverse section of the stem showed occasional prickling of the periderm. The transverse section of the leaves showed that the lower epidermal cells are covered by non-glandular hairs; the palisade cells and spongy tissues were clearly distinguished; the stomatic type of the lower epidermis was paracytic, with stomatal index of 31.76%. Fiber, scalariform vessels and spiral vessels, pollen grains and so on were commonly seen in the powder. Through chemical identification, polysaccharides, glycosides, alkaloids and other components were identified in the plant. TLC result shows that T-test result was 0.018, indicating significant difference. The pharmacognostic features of S. spatulifolius are obvious, providing reference for further utilization and development of this plant.
