Phytochemistry of some Useful forest Plants

Indian Forester (2004)

Rameshwar Dayal

Phytochemistry is the study of extraction, isolation and identification of plant chemicals viz; alkaloids, iridoides, phenolics, steroids, coumarins, terpenoides and others. These secondary metabolites play key role in the development of many new sources of plant - derived products. The isolation and characterization of new bioactive constituents from plants have become possible with the advent of latest sophisticated techniques such as chromatographic methods, multidimensional NMR and mass spectrometry. About one hundred twenty compounds were characterized using GC-MS for essential oils and latest spectroscopic methods like 2D NMR and other techniques for the pure compounds of which four compounds namely; artoflavanone, stipulin, luteolin-4'- rutinoside and quercetin-3-0-digalactoside were found to be new. A number of compounds were found to possess medicinal activity. This paper describes the isolation and characterization of chemical constituents from the different parts of nine plant species having biological activity.

Three Oleanolic Acid Glycosides from the Seeds of Achyranthes aspera

Natural Product Communications (2007)

Rashmi Gupta Rameshwar Dayal Akito Nagatsu

From the seeds of Achyranthes aspera three triterpenoid glycosides were isolated and their structures elucidated on the basis of NMR spectroscopic, mass spectrometric and degradative studies as α-L-rhamnopyranosyl-(1→4)-(β-D-glucopyranosyluronic acid)-(1→3)-oleanolic acid, α-L-rhamnopyranosyl-(1→4)-(β-D-glucopyranosyluronic acid)-(1→3)-oleanolic acid-28- O-β-D-glucopyranoside and α-L-rhamnopyranosyl-(1→4)-(β-D-glucopyranosyluronic acid)-(1→3)-oleanolic acid-28- O-β-D-glucopyranosyl-(1→4)-β-D-glucopyranoside.

Seasonal variation of the essential oil of Vitex negundo leaves

Indian Forester (2003)

Virendra Singh Rana Rameshwar Dayal

Studies to determine the appropriate month of harvesting of Vitex negundo leaves for the isolation of optimum amount of essential oil have been reported. The maximum oil yield (0.28%) was obtained in the month of October.

GC-MS Analysis of Essential Oil ofShorea RobustaBast

Journal of Asian Natural Products Research (2003)

Sandeep Kaur V. K. Varshney Rameshwar Dayal

GC-MS analysis of the essential oil of Shorea robusta bast (cambium + secondary phloem) has revealed the presence of twenty-eight compounds, of which nine compounds, constituting 48.79% of the oil, were identified as T-cadinol (16.75%), alpha-cadinol (16.45%), globulol (4.52%), alpha-copaene (3.79%), gamma-cadinene (2.34%), viridiflorene (1.62%), beta-elemene (1.54%), alpha-terpineol (1.33%) and gamma-muurolene (0.45%). This is the first report on the volatile constituents of the bast which may be significant in influencing host location for Hoplocerambyx spinicornis, the most injurious heartwood borer of Shorea robusta.

Rameshwar Dayal

Bryonolic acid; bergenin, hopeaphenol;ursolic acid; agnuside, virdiflorol; labdanyl-3α-ol-18-(3"-methoxy-2"-naphthyl-oate)-3α-L-arabinofuranosyl- (2'-1")-α-L-arabinofuranoside; stipulin and luteolin 4'-rutinoside were isolated and characterized from Tetrameles nudiflora, Vateria indica, Eucalyptus hybrid, Vitex negundo, Peucedanum grande and Dalbergia stipulacea respectively. These pure compounds were found to possess different pharmacological activities.
