Sedum sarmentosum is a traditional Chinese medicine with the clinical effects of clearing away heat and detoxification. It has the pharmacological effects of protecting liver, anti-tumor, anti-fibrosis, anti-oxidation, inhibiting lipid accumulation and immunosuppression. Because of its remarkable effect of reducing enzymes and protecting the liver, it is mainly used for the treatment of various types of hepatitis in clinical application. The flavonoids, megastigmanes, alkaloids, sterols, triterpenes and other chemical constituents in S. sarmentosum are the important material basis for its pharmacological action. In this paper, the research progress on the chemical constituents and pharmacological effects of S. sarmentosum were reviewed, and the research status and research direction of S. sarmentosum were analyzed, in order to provide a reference for its further rational development and application.

Objective: To study the chemical constituents from the hypocotyls of mangrove Bruguiera gymnorrhiza., Methods: The chemical constituents were isolated and purified by recrystallization, silica gel column chromatography and semi-preparative HPLC. Their structures were identified by spectroscopic analysis and comparison with literatures., Results: Seven compounds were isolated and their structures were identified as 3-β-(Z)-coumaroyllupeol (1), dioslupecin (2), cholesterol (3), menisdaurillide (4), aquilegiolide (5) vomifoliol (6) and roseoside II (7)., Conclusion: Compounds 1,2 and 4 - 7 are isolated from this plant for the first time.

Objective: To isolate the chemical constituents of the peelings of Citrus grandis and determine their structure., Method: Column chromatography and PTLC were applied to isolating and purifying the chemical constituents, and 1H NMR and 13C NMR were used to elucidate their structure., Result: 4 compounds were isolated as meranzin hydrate(1), roseoside(2), 8-(3-beta-D-syl-2-hydrox-3-methylbutyl)-7-methoxycoumarin(3) and glucose(4)., Conclusion: Compound 2 was isolated as a carotenoid from this genus for the first time.
