Mangroves have wide applications in folk medicine since ages due to the presence of several bioactive compounds. This study aims to explore the antimicrobial activity of ten mangroves commonly found in Indian Sundarban region namely Avicennia alba, Avicennia marina, Avicennia officinalis, Excoecaria agallocha, Sonneratia caseolaris, Sonneratia apetela,Aegiceres corniculatum, Acanthus ilicifoliu...

Three new naphthoquinones and their analogues, named avicequinone-A (1), -B (2), -C (3), and avicenol-A (4), -B (5), -C (6), respectively, were isolated from the stem bark of Avicennia alba (Avicenniaceae) collected in Singapore, and their structures were elucidated by means of spectral methods. Gillan and co-workers have proposed that the structures of the new phytoalexins isolated from Avicen...

Understanding the dynamics of mangroves at the species level is the key for securing sustainable conservation of mangrove forests around the globe. This study demonstrates the capability of the hyper-dimensional remote sensing data for discriminating diversely-populated tropical mangrove species. It was found that five different tropical mangrove species of Southern Thailand, including Avicenni...

In this present research, acetone extracts of Avicennia alba and Aegialitis rotundifolia were investigated for the estimation of their total phenolic content. The amount of total phenol present was calculated by assaying it with Folin’s Ciocalteau Reagent and spectrophotometric analysis. Gallic acid was taken as the standard compound and the total phenolic content of each of the plant sample wa...

Recruitment of non-planted mangrove species into Rhizophora mucronata, Sonneratia alba and Avicennia marina reforested stands (all of them 5 years old) was investigated to assess possibilities for natural colonization. Corresponding bare (denuded or open without mangroves) and natural (relatively undisturbed) sites were used as controls. Interstitial water salinity and temperature (measured at ...

Avicennia L. (Avicenniaceae), one of the most diverse mangrove genera, is distributed widely in tropical and subtropical intertidal zones worldwide. Five species of Avicennia in the Indo-West Pacific region have been previously described. However, their phylogenetic relationships were determined based on morphological and allozyme data. To enhance our understanding of evolutionary patterns in t...

The plant DNA barcoding is a complex and requires more than one marker(s) as compared to animal barcoding. Mangroves are diverse estuarine ecosystem prevalent in the tropical and subtropical zone, but anthropogenic activity turned them into the vulnerable ecosystem. There is a need to build a molecular reference library of mangrove plant species based on molecular barcode marker along with morp...

The present work deals with the isolation and structure elucidation of new flavones from methanol extract of Avicennia alba aerial parts. Isolation of the compound was carried out by chromatographic techniques, followed by different spectral analytical methods. The spectral data of UV-Vis, FT-IR, 1H NMR, 13C NMR and GC-MS of the isolated compound is in support of presence of flavone nucleus. Th...

Mangrove forests are ecosystems located in tidal areas coastal areas, beaches, and small islands. The area of ​​mangrove is decreasing due to the conversion mangrove into fishponds, plantations, timber exploitation. ecosystem rehabilitation activities need be carried out through planting. Avicennia alba a pioneer species that grows swamp habitats on sheltered locations, as well saltier parts co...
