Background: Cyclea peltata is one of the herbs mentioned in ancient scriptures of Ayurveda and is used in different types of Ayurvedic gritham preparations. Moreover, in traditional/tribal medicine C. peltata is used as digestive, anti-inflammatory, diuretic and to treat jaundice, digestive disorders, etc. OBJECTIVE: Activity guided fractionation of C. peltata and in correlation with the levels of bioactive compound tetrandrine.
Materials And Methods: Preliminary phytochemical screening, estimation of total alkaloid content, preparation of different extracts of C. peltata (crude extract CP, hexane extract HCP, chloroform extract CCP, methanol extract MCP, alkaloid fraction ACP). In vitro anti-inflammatory studies using RAW 264.7 cells and in vitro antioxidant assays of the different extracts of C. peltata. HPTLC estimation of tetrandrine (TET) was carried out using solvent system toluene: ethyl acetate: diethylamine (7.2: 2: 0.8) and isolation of TET from ACP.
Results: Preliminary phytochemical studies of C. peltata showed the presence of alkaloid content in all extracts. Whereas, saponins, steroids and terpenoids were detected in CP and CCP. ACP and TET showed significant in vitro anti-inflammatory and antioxidant activity when compared to other extracts. ACP and TET (100 μg/ml) treatment significantly inhibited the mRNA expression of iNOS, COX-2, TNF-α in LPS treated RAW 264.7 cells. HPTLC estimation of bioactive compound tetrandrine was highest in ACP-228.4 μg/mg followed by CP-29.62 μg/mg, CCP-23.46 μg/mg, MCP-18.82 μg/mg and HCP-1.25 μg/mg. TET has been isolated from ACP.
Conclusion: The results of the present in vitro assays revealed that the alkaloid fraction (ACP) is the most active fraction when compared to other extracts and has a positive correlation with the levels of bioactive compound tetrandrine.

Inflammatory bone resorption represents a pathological condition marked by an increase in bone loss, commonly associated with chronic inflammatory conditions such as rheumatoid arthritis and periodontitis. Current therapies primarily focus on anti-inflammatory drugs and bisphosphonates; however, these treatments are limited due to side effects, inadequate efficacy, and unpredictable long-term complications. Kurarinone (KR), a bioactive compound isolated from the traditional Chinese herb Sophora flavescens, exhibits a range of biological activities, including anti-inflammatory, anticancer, and cardiovascular protective effects.

One new Sesquiterpene wikstromicrol (1), one new lignan (7R, 8S, 8'S)-9-acetoxyl (-)-isolariciresinol (8), and twelve known compounds were isolated from the branches and leaves of Wikstroemia micrantha. The structures of new compounds were elucidated by extensive interpretation of spectroscopic data and quantum chemical calculations of ECD spectra. The bioactivity assay showed that compounds 6 and 7 had weak cytotoxicity against MCF-7, HCT-116, and HL-60 cell lines with IC50 values ranging from 33.
