<b>Physicochemical and antimicrobial properties of <i>Trichosanthes anguina</i> and <i>Swietenia mahagoni seeds</i></b>

Abstract

ABSTRACT ABSTRACT. The core objective of this research was to determine the characteristics of oils, nutritional composition and antimicrobial activities of T. anguina and S. mahagoni seeds. Physicochemical characteristics of oils implied higher degree of unsaturation in T. anguina whereas, S. mahagoni oil contained appreciable level of unsaturation. Tri-acyl-glycerols and neutral lipids were found to be most abounded components recorded to 86.2 and 91.3% for T. anguina and 87.0 and 89.4% for S. mahagoni, respectively. GLC analysis showed the presence of fatty acids from series C16:0 to C18:3 for T. anguina and C16:0 to C20:0 for S. mahagoni in which principal fatty acids accounted as punicic (45.1%) in T. anguina and linoleic (30.1%) in S. mahagoni seed oils. Of the major energy producing nutrients, the seed samples contained large amounts of lipid (36.1% in T. anguina and 57.9% in S. mahagoni) and protein (20.9% in T. anguina and 13.0% in S. mahagoni) and potentially useful amounts of other nutrients. The knowledge from the nutritional analysis could be important to its appropriate industrial use and for improvement in the nutritional value. Assessment of the anti-microbial studies reported herein revealed the crude extracts of T. anguina and S. mahagoni seeds were not significantly inhibition against most of the tested bacteria and fungi. This study may lead to further ethno-pharmacognostic investigations to identify new compounds with therapeutic promise. KEY WORDS KEY WORDS KEY WORDS

Swietenia mahagoni seed oil: A new source for biodiesel production

“…The tree having seeds chestnut brown in colour, 4-5 cm long (Schmidt and Joker, 2000) and are potentially rich in fat (57.9%) as reported in previous study (Ali et al, 2011). Swietenia mahagoni seed oil consists of linoleic, oleic, stearic, linolenic and palmitic fatty acids (Ali et al, 2011).…”

“…The oil was not exploited much to develop value-added products. There exist some studies on the analysis and usage of Swietenia mahagoni oil, crude extracts, phenolic compounds for antioxidant, antimicrobial applications (Ali et al, 2011;Mostafa et al, 2011;Subhadip et al, 2011). As this is a tree borne seed-based oil, there will be a good scope for utilizing this oil as a potential feedstock for biodiesel production.…”

Fatty Acid Composition and Antibacterial Activity of Neem (Azadirachta indica) Seed Oil

“…Neem (A indica) seed fixed oil on its own might not able to behave as a strong antibacterial agent. Besides Neem (A indica), there are various plant been identified in behaving as therapeutic agent towards fighting the bacteria such as the Swietenia mahagoni oil, Aniseed oil, Calamus oil, Camphor oil, Cedarwood oil, Clove oil, Lavender oil, Lomongrass oil, Lime oil, Nutmeg oil, Basil oil, Peppermint oil and Rosemary oil [19][20][21][22][23][24][25]. Therefore, suggestions on the combination of the oil of one plant with oil of another plant and also a combination of plant oil with commercial drugs could be practiced as it proves that the synergistic combinations yield in better outcomes in fighting against these bacteria that ruin human's life [16].…”

Comparative performance and digestive physiology ofDiaphania indica(Lepidoptera: Crambidae) onTrichosanthes anguina(Cucurbitaceae) cultivars

“…The fruit is a rich source of vitamins A, B and C. In traditional medicine, the plant is used as an appetizer, laxative, aphrodisiac, blood purifier (Sivarajan and Balachandran, 1994) and for treatment of wounds including boils, sores, skin eruptions such as eczema and dermatitis (Pullaiah, 2006). The whole plant has an immense medicinal value such as antidiabetic (Arawwawala et al ., 2009), gastro-protective (Arawwawala et al ., 2010 a ), anti-inflammatory (Arawwawala et al ., 2010 b ) and antimicrobial activity (Ali et al ., 2011; Patil and Kannapan, 2014). The whole plant is also a good source of antioxidants (Arawwawala et al ., 2011).…”
