The findings of the present study confirm the presence of significant antibacterial activity against human pathogens in the flowers of Peltophorum pterocarpum.
Sacred groves are forest patches conserved by the local people through religious and cultural practices. These groves are important reservoirs of biodiversity, preserving indigenous plant species and serving as asylum of Rare, Endangered and Threatened (RET) species. The present study was carried out in Muppuram coastal sacred grove of Kanyakumari district to reveal the plant diversity, structure and regeneration pattern of trees using quadrate method. About 102 plant species were recorded from the total area (0.2 ha) of the grove studied. The vegetation of the grove clearly indicates tropical dry evergreen forest. Malvaceae was the dominant family. Young plant species were dominating than older ones (> 160 cm). To avoid the rapid environmental degradation of the sacred grove, conserving the groves is urgent and it is necessary to conduct more researches on this grove as well as other groves of the district.
Objective: To make scientific validation of the flowers of the endemic palm Arenga wightii Griff. in relation to phyto chemistry and antimicrobial activity by agar disc diffusion method. Key Findings: Among the three extracts tested against twelve pathogenic bacteria, acetone flower extract was effective against Bacillus cereus, Staphylococcus aureus and Streptococcus pyogenes, while chloroform extract was effective against B. cereus, S. aureus, Serratia marcescens and St. pyogenes, while aqueous extract was effective against the gram negative strain Enterobacter sp. and Acinetobacter baumannii. The fungal strains showed no response to the flower extracts. Preliminary phytochemical screening showed the presence of phyto constituents viz. steroid, tannin, xantho proteins, phenols, flavonoid, coumarin, saponin and carbohydrates. Conclusion: It may be concluded that the crude extracts obtained from the flowers of A. wightii may be used as drug to treat disease caused by the bacteria. Therefore, further investigations are needed to isolate and characterize their active compounds for pharmacology testing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
