“…The fruits of C. taliera were collected from the lone individual existed in the campus of the University of Dhaka and a voucher specimen was deposited at the department of Botany, University of Dhaka (Khondker et al 2010). The pericarp were separated from the seeds of dried fruits and made into powder.…”

A new steroidal glycoside, β-sitosterol-3-O-α-L-rhamnopyranosyl-(1→4)-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→4)-β-D-glucopyranoside was isolated from the methanol extract of the pericarp of Corypha taliera Roxb. The reversed-phased HPLC analysis of the methanol extract of the pericarp of C. taliera Roxb. (Talipalm), a rare species of Arecaceae family, afforded a new steroidal glycoside, β-sitosterol-3-O-α-L-rhamnopyranosyl-(1→4)-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→4)-β-D-glucopyranoside (1). The structure of the compound was elucidated unequivocally by UV, IR, HR-ESI-MS, (1)H and (13)C NMR spectroscopic studies.

“…Significant evidence regarding economic value, botanical information including panicle initiation, flowering and fruiting as well as biochemical composition of flowers and fruits of the plant have been recorded primarily (Shoeb et al, 2015;Khondker et al 2010). Recently, phytochemical screening revealed that the unripe fruits contain significant bioactive molecules including βsitosterol, β-amyrin, betulinic acid, lupeol (Chowdhury et al, 2013), palmitic, myristic, linoleic, arachidic, stearic, lignoceric acids (Shoeb et al, 2013 and (Shoeb et al, 2015).…”

Chemical Constituents and Protection of Biodiversity of Corypha taliera Roxb., a Critically Endangered Plant of Bangladesh

This article focuses on the chemical constituents and protection of biodiversity through plantation of saplings of Corypha taliera Roxb., a critically endangered plant of Bangladesh. Until 2010, the tree in the campus of University of Dhaka, used to be considered as the lone surviving species in the world in nature. Succesive chromatographic separation and purification of the methanol extract of air dried flowers of C. taliera provided β-sitosterol (1), β-amyrin (2), and betulinic acid (3) for the first time from its flowers. The structures of these purified compounds were established by extensive spectroscopic analysis and comparison of spectral data with published values as well as co-TLC with authentic samples. On the other hand, 500 mature seeds were sown in seed beds in the Medicinal Plant Garden of Faculty of Pharmacy, University of Dhaka, and Azimpur Government Officers' Quarter premises. After 40 days, the root was first seen to grow in its habitat and 85 days later the shoot developed up to 2.5 cm in height. The rate of germination was found to be 89-93%. The produced saplings were later on planted in different places of Bangladesh for conservation of the plant and protection of biodiversity by ex situ arrangement.

“…There are four species of the genus Corypha, namely Corypha taliera, C. umbraculifera, C. elata and C. macropoda available in the Indian subcontinent. C. taliera locally known as Talipalm, is a globally endangered species (Khondker et al 2010). The existence of C. taliera in Bangladesh was identified by late Prof. Salar Khan in 1950 in the Dhaka University Campus, Dhaka (Khondker et al 2010).…”

Ab initio calculations were carried out to studysolvation free energy, dipole moment, molecular electrostatic potential (MESP), Mulliken charge distribution, polarizability, hyperpolarizability and different molecular properties like global reactivity descriptors (chemical hardness, softness, chemical potential, electronegativity, electrophilicity index) of betulin. B3LYP/6-31G(d,p) level of theory was used to optimize the structure both in gas phase and in solution. The solvation free energy, dipole moment and molecular properties were calculated by applying the Solvation Model on Density (SMD) in six solvent systems namely water, dimethyl sulfoxide (DMSO), acetonitrile, n-octanol, chloroform and carbontetrachloride. The solvation free energy of betulin increases with decreasing polarity of the solvent. No systematic trend of hyperpolarizability with solvent polarity is found. Molecular electrostatic potential (MESP) and Mulliken population analysis (MPA) reveal that the most possible sites for nucleophilic attack are C30, H76 and H77 and electrophilic attack are O1 and O2 among the atoms in betulin. However, the dipole moment, polarizability, chemical potential, electronegativity and electrophilicity index of betulin increase on going from non-polar to polar solvents. Chemical hardness was also increased with decreasing polarity of the solvent and opposite relation was found in the case of softness. These results provide better understanding of the stability and reactivity of betulin in different solvent systems.
