Plants are important source of medicine and drugs, they contain many bioactive constituents that produce definite physiological and biochemical actions in the human body. Medicinal plants are great importance to the health of individuals and play a signifi cant role in traditional and modern drug system. Ceropegia bulbosa Roxb.var. lushii (Grah.) Hook.f. is one of the medicinally important and endangered plant (Asclepiadaceae), reported from some places of Rajasthan. The aim of present study was to determine the preliminary phytochemicals and bioactive components using standard analytical procedures and Perkin-Elmer Gas Chromatography-Mass Spectrometry of the whole plant in three extracts i.e. methanol, chloroform and hexane. The mass spectra of the compounds found in the extract was matched and compared with the National Institute of Standards and Technology (NIST) library. Methanol and chloroform extract shows better results as compared to hexane extract. This investigation conclu des that extract of this plant contains various biologically active constituents and justifies its use for noval drug development.

“…Verificou-se que para as diferentes partes da planta houve um aumento crescente na concentração de fenólicos totais, sendo que a menor concentração encontrada foi para folha e maior para flor. Ramu et al (2012) avaliaram o teor de fenólicos totais nas folhas de Plectranthus mollis, encontrando valores consideráveis para tal, o que confirma os resultados encontrados em nosso trabalho e indica que a espécie apresenta compostos fenólicos. Esses dados foram estatisticamente analisados pelo teste de Tukey, onde se pode observar que o teor de fenólicos totais na flor e ramo não apresentam diferenças estatisticamente significativas, já a folha não apresenta diferença significativa em relação à flor, ramo e inflorescência, porém a última é estatisticamente diferente dos demais.…”

“…Resultados que corroboram com aqueles encontrados por Grayer et al (2010), que analisaram a composição química da Plectranthus barbatus L. encontrando compostos como quercetina e canferol. Ramu et al (2012) avaliaram as folhas de Plectranthus mollis e identificaram a presença de compostos como ácido cafeico, quercetina e luteolina. Kubínová et al (2013) avaliaram as folhas de Plectranthus forsterie encontraram compostos como ácido cafeico, confirmando a composição encontrada no presente estudo.…”

“…Inhibitory interaction test of extract S. alba against pathogenic bacteria associated with ice-ice disease was performed by using the agar disk diffusion method according to Refs. [13,14] with slight modification. Antibacterial assay plates were prepared by pouring 20 ml of Zobell marine agar and allowed to solidify.…”

The Performance of Mangrove Leaf Extract (Sonneratiaalba) in Combating Bacterial Associated with Ice–Ice Disease of Seaweed (Kappaphycusalvarezii)

The outbreaks of ice-ice disease since 1999 at various seaweed culture in Indonesia were still very high with significant losses. Moreover, very scanty of the research on the cause and control methods has been developed. Meanwhile, Mangrove leaf extract (Sonneratiaalba) contained bacteriostatic that might potentially effective to combat a such disease. This research was aimed to demonstrate the performance of mangrove leaf extract to control bacteria causing ice-ice disease. Mangrove leaf (S. alba) was extracted by methanol. Nine bacterial collection from the ice-ice were then in vitro-exposed to mangrove extract at concentration of 2500, 5000 and 10,000 mg/l respectively. Research results demonstrated that mangrove leaf extract at all concentrations tested were able to prevent the growth of 9 bacterial strains associated with ice-ice disease. The diameter of clear zone was between 7.47 and 16.17 mm after 24 hours incubation. Thus, it can be concluded that alkaloid, saponin, tannin, triterpenoid/steroid, and flavonoid in the mangrove leaf at concentration as low as 2500 mg/l was able to prevent the growth of 9 bacterial associated with ice-ice disease.
