Curcuma zedoaria (Berg.), belongs to the Zingiberaceae family, is one of the medicinal plants that is found in Southeast Asia. This plant is known as “Nghe tim” in Vietnam; and a decoction of its rhizomes has been used traditionally for the cure flatulence, fatigue, and hepatitis. Previously, some studies on the chemical constituent of the rhizomes of C. zedoaria have reported plenty of curcuminoids and sesquiterpenoids together with their derivatives, which have shown a lot of various bioactivities such as antiproliferative characteristic, anti-ulcer, antioxidant and antibacterial potential. By chromatography column method along with preparative thin layer chromatography on a normal phase silica gel on the EtOAc extract of the rhizomes of Curcuma zedoaria, we have isolated five pure compounds. Their chemical structures have been elucidated by NMR techniques and comparison with publishing data that have determined to be gajustulactone A (1), isozedoarondiol (2), neolitacumone (3), β-sitosterol (4), and β-stigmasterol (5). The results of this study have contributed to the scientific data system on the chemical composition of Vietnamese medicinal plants, especially the rhizomes of Curcuma zedoaria grown in Tinh Bien, An Giang. Therefore, there is more evidence to continue screening studies to detect interesting biological activities from this species.

And Control

Hyperlipidemia is the immediate results of the excessive fat intake in food. This results in the elevated levels of cholesterol and triglycerides in the blood. This leads to heart conditions like CAD, hypertension, congestive heart failure as risk factors which can be lethal. There are many drugs to treat and control the lipids levels in the body. These drugs are either designed to prevent LDL accumulation and VLDL synthesis. Some drugs also lower the elevated levels of saturated lipids in the body. But many drugs are known to cause side effects and adverse effects; therefore, alternatives to the drugs are the subjects for current investigations. Herbs and medicinal plants are used as treatment sources for many years. They have been used in the Indian medical systems like Ayurveda, Siddha etc. As the application of herbs in the treatment is growing, there is an urgent need for the establishment of Pharmacological reasoning and standardization of the activity of the medicinal plants. Chloris paraguaiensis Steud. is Poyaceae member that is called locally as Uppugaddi. Traditionally it is used to treat Rheumatism, Diabetes, fever and diarrhoea. The chemical constituents are known to have anti-oxidant properties and most of the anti-oxidants have anti-hyperlipidemic activity too. Since the plant has abundant flavonoid and phenol content, the current research focusses on the investigation of the anti-hyperlipidemic activity of the plant Chloris extracts. Extracts of Chloris at 200mg/kg showed a comparably similar anti hyperlipidemia activity to that of the standard drug. The extracts showed a dose based increase in the activity at 100 and 200mg/kg body weight.

Background: Peptic ulcer is a deep gastrointestinal erosion disorder that involves the entire mucosal thickness and can even penetrate the muscular mucosa. Nowadays, several plants and compounds derived from it have been screened for their antiulcer activity. In the last few years, there has been an exponential growth in the field of herbal medicine. This field has gained popularity in both developing and developed countries because of their natural origin and less side effects. Objective: This review aims to provide a comprehensive summary of currently available knowledge of medicinal plants and phytoconstituents reported for their anti-ulcer properties. Methods: The worldwide accepted database like SCOPUS, PUBMED, SCIELO, NISCAIR, ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar were used to retrieve available published literature. Results: A comprehensive review of the present paper is an attempt to list the plants with antiulcer activity. The review narrates the dire need to explore potential chemical moieties that exert an antiulcer effect, from unexploited traditional plants. Furthermore, the present study reveals the intense requirement to exploit the exact mechanism through which either the plant extracts or their active constituents exhibit their antiulcer properties. Conclusion: This article is the compilation of the plants and its constituents reported for the treatment of peptic ulcers. The Comprehensive data will surely attract the number of investigators to initiate further research that might lead to the drugs for the treatment of ulcers. As sufficient scientific data is not available on plants, most of the herbals cannot be recommended for the treatment of diseases. This can be achieved by research on pure chemical structures derived from plants or to prepare new lead compounds with proven beneficial preclinical in vitro and in vivo effects. However, a lot remains to be done in further investigations for the better status of medicinal plants.
