Abstract:
Phytochemical investigation of Cissus quadrangularis stems led to the isolation of one new phenolic glycoside (1) and two new lignan glycosides (7 & 8) along with twelve known compounds (2-6 & 9-15). Their chemical structures were determined on the basis of extensive spectroscopic analysis using 1D, 2D NMR, and mass spectrometric analysis. Among the known compounds, 4-6, 9 and 12 were isolated for the first time from the genus Cissus whereas compounds 10, 11 and 13 for the first time from this plant.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
