The leaf terpenoid compositions of nine Lauraceae species, viz., Neolitsea pallens, Lindera pulcherrima, Dodecadenia grandiflora, Persea duthiei, Persea odoratissima, Persea gamblei, Phoebe lanceolata, Cinnamomum tamala, and Cinnamomum camphora, collected from the Himalayan region (India) were examined by GC, GC/MS, and NMR analyses in order to determine the similarities and differences among t...

Afforestation plays an important role in soil protection and ecological restoration. The objective of this study is to understand the effect of afforestation on soil carbon and soil microbial communities in the Loess Plateau of China. We measured two chemically-separated carbon fractions (i.e., humic acid, HA, and fulvic acid, FA) and soil microbial communities within shrublands (18-year-old Ca...

Seed oils of Passiflora edulis, Jatropa curucas, Tinospora cordifolia, Sesbania grandiflora and Sapindus laurifolia were investigated for their antihelmintic property against Pheritima pasthuma. Three concentrations (10, 50 and 100 mg/ml) of each oil were studied in the bioassay, which involved the determination of time of paralysis and time of death of the worm. Sesbania grandiflora showed the...

The present study was aimed to evaluate the phytochemical constituents and antibacterial activity of the flower extracts of Albizia lebbeck, Cordia sebestena, Thunbergia grandiflora and Antigonon leptopus. Preliminary phytochemical screening was done by the standard methods described by Harborne. Antibacterial study was carried out by disc diffusion method. The results of the phytochemical anti...

Beaumontia grandiflora Wall. (Apocynaceae) is an ornamental plant cultivated in Egypt. Investigation of the chemical constituents of the aerial parts of B. grandiflora Wall. in pet. ether extract led to isolation and identification of twelve fatty acids in which linoleic acid (29.60%) and Palmitic acid (19.12%) are the main acids. The unsaponifiable fraction was found to contain a series 14 27 ...

The comparative chromosomal features of four species belonging to family Apocynaceae from Northeastern Thailand were studied the root tips. somatic chromosome numbers all specimens found be 2n = 36 for Allamanda blanchetii, 18 A. cathartica, 20 in schottii and 52 Cryptostegia grandiflora. cathartica have same number previous except C. grandiflora differs previously reported. Moreover, has never...
