Important chemicals that have been found in the plant include betulinic acid, ellagic acid, gallic acid, germanicol, germanicone, lupeol, stigmasterol and taraxerol. Antibacterial, antifungal and antinociceptive activities have been reported for extracts from the plant. Traditional medicine practices include the whole plant as a remedy for itch; the roots are considered to be antimalarial, the bark and/or leaves are used in case of boils, snake bites, rat poisonings, gastric ulcer, high blood pressure, chicken pox and as a depurative, the fruits are used as remedy for cough, asthma and diarrhea, while the seeds are used for cancer like diseases and for eye inflammation.

In this study the anti-arthritic effect of Chloroform extract of the leaves was evaluated and compared to untreated control. Complete Freund's Adjuvant (CFA)-induced arthritis model was done by using two techniques includes Prophylactic and Therapeutic model. Arthritis was induced by injecting CFA subcutaneously into the left hind paw. Paw volumes were recorded on the day of injection, 7, 14 and 21 st day by using plethysmometer and compared. The results showed that Chloroform extract of the leaves of B. acutangula(CEBA)has significant anti- arthritic activity when compared to control group in both studies. This study supports the traditional use of B. acutangula for the treatment rheumatoid arthritis and suggests further studies to produce clinically useful herbal drug.

The dichloromethane extract of branches yielded the triterpene 3β-methoxy-lup-20(29)-ene (4). The chemical structures were characterized by NMR data. Plant extracts, substance 3, squalene (5) and taraxerol (6), (5 and 6 previously isolated), were evaluated by in vitro assay against chloroquine resistant Plasmodium falciparum.

In the past few decades, however, these mangrove forests have been largely degraded and destroyed during the process of development. The negative environmental and socio-economic impacts on mangrove ecosystems have led many government and non- government agencies, together with civil societies, to launch mangrove conservation and rehabilitation programmes, especially during the 1990s. In the course of such activities, programme staff have faced continual difficulties in identifying plant species growing in the field. Despite a wide availability of mangrove guidebooks in Southeast Asia, none of these sufficiently cover species that, though often associated with mangroves, are not confined to this habitat.

In Tamil, it is known as Samutraphalam.The present study is an attempt to explore the anthelmintic activity of ethanolic extract of leaves of plant Barringtonia acutangula. The purpose of the present study was to find out the anthelmentic activity of ethanolic extract of Barringtonia acutangula in earthworms. The various doses of ethanolic extracts were evaluated for their anthelmintic activities on adult Indian earthworms, Pheretima postuma. All doses of ethanolic extracts were able to show anthelmintic activity. The activities are well comparable with the standard drug Piperazine citrate . All the doses of ethanolic extract of Barringtonia acutangula showed better anthelmintic activity. When the dose of the extract is increased, a gradual increase in anthelmintic activity was observed. Keywords : Barringtonia acutangula, Anthelmintic activity, Piperazine Citrate. Introduction: There are no reports on systematic and Barringtonia acutangula belongs to the family scientific study of anthelmintic activity of leaf Lecythidaceae and also called as Indian Oak extracts. In the present study, we report the (English), Ijal (Hindi), Samuttirappalam (Tamil), anthelmintic activity of ethanolic extract of the leaves Kanapa – chettu (Telugu) and Kinijolo (Oriya) in of Barringtonia acutangula.

ORIGINAL ARTICLE ORIGINAL Bulbine natalensis is one of several South Africa’s indigenous succulent medicinal species. B. natalensis’ high medicinal profile has made it a commercially-available herb within the South African market and beyond. However, there is a limited scientific report on its bioactive metabolites. Objectives: This study’s objective was to isolate and identify bioactive compounds from B. natalensis leaves and evaluate the compounds and crude extracts for antioxidant activity. Materials and Methods: Fractionation and purification of B. natalensis dichloromethane extract were done using chromatographic techniques. Whole extract profiling was carried out on dichloromethane and methanol extracts using gas chromatography-mass spectrometry (GC-MS). The isolated compounds and extracts were evaluated for antioxidant activity. Results: The dichloromethane extract yielded two pentacyclic triterpenes (glutinol and taraxerol), one tetracyclic triterpene

ABSTRACT The present study was undertaken to investigate the effects of Barringtonia acutangula (L.) on learning and memory in mice. Morris water maze and passive avoidance paradigm were employed to test learning and memory. Two doses (100 and 200mg/kg, p.o.) of methanolic extract were administered for 21 successive days in separate group of animals. The dose of 200 & 400‐mg/kg p.o. of EEBA significantly improved learning and memory of mice in dose dependent manner. Furthermore, this dose significantly reversed the amnesia induced by Corticosterone (5 mg/kg, s.c) induced amnesia. Hence Barringtonia acutangula (L.) appears to be a promising candidate for improving memory and it would be worthwhile to explore the potential of this plant in the management of dementia and Alzheimer’s disease. However, further studies are necessitated to identify the exact mechanism of action. Keywords: Barringtonia acutangula (L.), Alzheimer’s disease.
