During fungal diversity surveys of the order Eurotiales in Korea, two fungal strains, EML-DG33-1 and EML-NCP50, were isolated from samples of rat dung and fig tree leaf collected at a garden located in Gwangju in 2014. To complete the National Species List of Korea, it is a prerequisite to verify whether many questionable species, which were previously recorded but not confirmed, indeed present...

A new species of spiral ginger (Costus: Costaceae) from Gabon, Africa is described. Costus loangensis H. Maas & Maas is found in the coastal region on white sand soils under a tropical rain forest canopy. It is morphologically distinct from all other African species of Costus but shows some similarities in floral form with the savanna-inhabiting Costus spectabilis (Fenzl) K. Schum. and similari...

Bioassay-guided fractionation of the extract from the fermentation broth of Streptomyces spectabilis BCC 4785 led to the isolation of three principle antimalarial agents, metacycloprodigiosin, bafilomycin A(1), and spectinabilin. Metacycloprodigiosin exhibited potent in vitro activity against Plasmodium falciparum K1, with a 50% inhibitory concentration of 0.0050 +/- 0.0010 microg/ml, while its...

Spectinabilin is a rare nitrophenyl-substituted polyketide metabolite. Here we report the cloning and heterologous expression of the spectinabilin gene cluster from Streptomyces spectabilis. Unexpectedly, this gene cluster is evolutionarily closer to the aureothin gene cluster than to the spectinabilin gene cluster from Streptomyces orinoci. Moreover, the two nearly identical spectinabilin gene...

SNF4435C and D are new immunosuppressants isolated from the culture broth of a strain of Streptomyces spectabilis. Their molecular formulas were determined as C28H31NO6 based on the HRFAB-MS analyses. The structures of SNF4435C and D were elucidated to be novel nitrophenyl pyrones having an intriguing tricyclic ring system and diastereoisomers of each other by spectroscopic analyses including v...

Bougainvillea purple flowers (bougenvillea spectabilis) is a plant that contains secondary metabolites one of them flavonoids. This study aims to identify the type flavonoids in bougenville blend n-butanol. The identification bougainvillea n-butanol fraction was performed by separation method using preparative TLC eluent nbutanol: acetic acid: water (4: 1: 5) 3 stains with Rf 0.2, 0.3, and 0, 6...

Young rats fed on a diet which contains Crotalaria spectabilis seeds or the pyrrolizidine alkaloid monocrotaline die from congestive heart failure within 36 to 60 days. At necropsy they are found to have ascites, pleural effusions, and cardiac enlargement due to right ventricular hypertrophy (Turner and Lalich, 1965; Kay and Heath, 1966). Microscopic examination reveals an increase in the media...

Dyslipidemia is major problem among population those have sedentary life style as well as in diabetics. Bougainvillea spectabilis is most commonly found in India as an ornamental plant and has got anti-diabetic action due to presence of one insulin mimicking agent D-pinitol (3-O-methyl-chiroinositol). The present investigation was undertaken to evaluate the effect of alcoholic extract of leaves...
