“…Regarding the type of processing, lyophilized samples allowed the best results for all assays, except for DPPH • scavenging activity, where it was not possible to differentiate from lyophilized and boiled samples. The detected amounts of bioactive compounds are generally in agreement with previous results in alcoholic extracts of elephant foot yam (Angayarkanni et al, 2010;Nataraj et al, 2009). Since the antioxidant activity is often correlated with the contents in total phenolics of a determined matrix (Razali et al, 2012), the correlation coefficients among bioactive compounds and antioxidant activity were also calculated.…”

“…Besides the individual variations, some general conclusions might also be drawn from the EMM: for instance, the highest amounts of total phenolics (132 mg GAE/L extract) and total tannins (129 mg GAE/L extract), as well as the most powerful FRAP (505 mg FSE/L) were achieved with the hydroalcoholic solvent; aqueous extracts revealed the lowest contents in total phenolics (43 mg GAE/L extract), total flavonoids (18 mg ECE/L extract) and also the weakest DPPH • scavenging activity (26%) and FRAP (116 mg FSE/L extract); total tannins content presented the least value (29 mg GAE/L extract) in ethanol extracts. In previous studies, ethanol extracts were reported as having the highest antioxidant efficiency along with the high content of phenolic compounds (Angayarkanni et al, 2010;Jayaprakasha et al, 2008). Herein, the best results were obtained with water:ethanol (1:1), potentially indicating the presence of phenolic acids (which are readily soluble in water) or a high percentage of glycosylated phenolics (it is a well-known fact that glycosylation increases the water solubility of phenolic compounds).…”

Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson) is an underground, unbranched deciduous plant that produces a large tubercle (rhizome) with recognized health effects. In this study, the influence of solvent nature (water, water/etanol (1:1) and absolute ethanol) and processing type (fresh, lyophilized and boiled) on the antioxidant activity and bioactive compounds extractability of elephant foot yam was evaluated. Extracts were compared for their contents in total phenolics, flavonoids and tannins. Moreover, their antioxidant capacity was assessed by the ferric reducing antioxidant power (FRAP) and the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH •) scavenging capacity assays. Phenolics (154 mg GAE/L) and tannins (109 mg GAE/L) were maximized in lyophilized samples extracted with the hydroalcoholic solvent, which attained also the highest FRAP value (711 mg FSE/L). In turn, flavonoids reached the highest yields in lyophilized samples (95 mg ECE/L) extracted with pure ethanol, as well as the highest DPPH • scavenging activity. These findings might have practical applications to define the best processing methodology regarding the enhancement of elephant foot yam, either for prompt consumption, as well as to develop food supplements or pharmaceutical related products.

“…Phytopharmacological properties have been shown in A. paeoniifolius, G. speciosa, and J. curcas [7][8][9]. For example, the antioxidant activity of A. paeoniifolius correlated to phenolic content [10], antiseizure activities of G. speciosa [8], and antimetabolic constituents of J. curcas [9]. These studies suggested that these mangrove associates are regarded as medicinal values.…”

“…The existence of polyisoprenoids has been referred to various plant tissues either in vegetal: leaves and roots [3][4][5][6], and reproductive: flowers, fruits, and seeds [10][11]. These studies divulged the universal distribution of polyisoprenoids in the plant kingdom.…”

Coastal plants are recognized to yield secondary metabolites including polyisoprenoid alcohols. Coastal plants have been shown to have biological and phytochemical activities. The present study reports the search for polyisoprenoids composition from flowers and fruits of selected coastal plants, Amorphophallus paeoniifolius, Guettarda speciosa, and Jatropha curcas. A two-dimensional thin layer chromatography (2D-TLC) was used to analyse the composition and occurrence of polyisoprenoid alcohols (polyprenols and dolichols) in coastal plants. The distribution of polyprenols and dolichols in the flowers and fruits were detected and classified into one type only, type-II. Type-II, having the presence of both polyprenols and dolichols, was found in all samples investigated: in the flowers and fruits of A. paeoniifolius, G. spiciosa, and J. curcas. It is interesting to note that no dominating dolichols over polyprenols (type-I) or predominance polyprenol over dolichols (type-III) detected in this study. The present study, therefore, suggested the diversity of polyisoprenoids in the generative tissues of tropical coastal plants.

“…Several studies have been conducted globally to prove the efficacy of phytochemicals. India is a rich emporium of medicinal plants, mainly used in preventive and curative medicine 7 . This heritage based on ayurvedic and homeopathic systems of medicine, is predominantly plant based and materia medica has already been compiled in ancient Indian texts such as Rigveda, Sushruta Samhita and Charaka Samhita.…”

Modern antibiotics against acne vulgaris has led to resistance among Propionibacterium acnes. This may be overcome with the use of ancient Indian medicines documented against skin diseases. Methanolic extracts of 21 medicinal plants were screened for antipropionibacterium activity to provide a scientific basis for indigenous cures derived from traditional knowledge. Seven medicinal plants were found to inhibit the gr owth of P. acnes. Of these Embelia ribes, Salmalia malabarica and Terminalia chebula showed strong inhibitory effects. The novel antipropionibacterium activity of embelin isolated from Embelia ribes and chebulagic acid isolated from Terminalia chebula which strongly inhibited the growth of P. acnes with minimum inhibitory concentration of 12.5 μg/ml has been reported.
