Effect of degree of silanization of luffa on the properties of luffa-epoxy composites
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2020Abstract Luffa fibers were silane functionalized using varied concentrations of 3-aminopropyl trimethoxysilane (APTMS) in methanol solution to investigate the relationship between the concentration of silanizing agent and the effective degree of silanization of luffa fibers. The aim of the present work was to identify the optimal silane concentration

Reverse transcription real-time quantitative PCR is widely used to quantify gene expression. Reference genes are usually used as internal controls to measure the target gene expression level. To date, there is no consensus on the use of systematically validated reference genes in different tissues of Luffa. This study evaluated the expression stability

Flavonoids and the systematics of Luffa
Biochemical Systematics and Ecology, 1981Abstract Flavonoids were characterized from leaves and flowers of six species of Luffa . Each species had a distinct flavonoid pattern. Based on leaf flavonoids, Luffa is separable into two groups of species: L. graveolens and L. operculata contain only flavonols. L. acutangula, L. aergyptiaca, L. echinata and L.

Nutritional and oil characteristics of the seeds of angled Luffa Luffa acutangula
Food Chemistry, 1982Abstract Luffa seeds (L. acutangula), a member of the Cucurbitaceae family, were investigated for their potential nutritional and oil characteristics. The yield of seeds from the fruit was 33ยท5%, while the kernel was found to possess 50% of the seed weight.

A luffa is a natural vegetable sponge. With its skin on, it resembles a cucumber or a zucchini, and it is a member of the same family. Though widely grown, luffas are rarely studied. Since we discovered luffas in North Carolina back yards several years ago, we have found this gourd to be a wonderful science teaching tool.

Mechanical properties of luffa sponge
Journal of the Mechanical Behavior of Biomedical Materials, 2012The paper presents the first scientific study of the stiffness, strength and energy absorption characteristics of the luffa sponge with a view to using it as an alternative sustainable engineering material for various practical applications. A series of compression tests on luffa sponge columns have been carried out.

Journal of Biomechanics, 2014
Cellular materials that are often observed in biological systems exhibit excellent mechanical properties at remarkably low densities. Luffa sponge is one of such materials with a complex interconnecting porous structure. In this paper, we studied the relationship between its structural and mechanical properties at different levels of its hierarchical ...

The American Species of Luffa (Cucurbitaceae)
Systematic Botany, 1988Three species of Luffa are recognized as indigenous to tropical America: L. astorii, found sparingly in Venezuela, Ecuador, and Peru; the widespread L. operculata which ranges from Panama into Brazil and Peru; and L. quinquefida which extends from western Mexico to Nicaragua.
