Objective of present study was to isolate, analyze and identify the phytochemicals composition from steam of Caralluma quadrangula. Methods: Extractions of the chemical components was carried out by different chromatographic techniques. The phytochemical characterizations were evaluated by nuclear magnetic resonance and mass spectrometry. Results: The quantitative phytochemical analysis of this species exhibited the presence of three compounds, Glochidonol (5gm), Dihydroxy-14-pregn-5-en-20-one (9.8gm), Hydroxystigmast-5-en-7-one (7.8gm) and Stigmasterol (5.7 mg). Hydroxystigmast-5-en-7-one, report from Caralluma quadrangula stem as first time. Conclusion: The present study is strengthen for the discovery three pure chemical compounds from C. quadrangula. Peer Review History: Received 2 April 2019; Revised 22 April; Accepted 7 May, Available online 15 May 2020 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
