Nutritional assessment and bioactive potential of Sargassum polycystum C. Agardh (Brown Seaweed)

492-498The phytochemical screening, nutritional composition and bioactive potential of Sargassum polycystum (Brown Seaweed) were investigated. The bioactive compounds of Sargassum polycystum showed significant activity against four human pathogens, namely, Bacillus subtilis, Escherichia coli, Staphylococcus aureus, and Klebsiella pneumoniae. The biochemical composition of Sargassum polycystum exhibited high nutritional potential of protein (14.2%), carbohydrate (25.0%), lipid (7.6%), fiber (21.3%), and ash (29.0%) than that in terrestrial plants and animal products. The Sargassum polycystum could be providing more opportunities for discovering new drugs which may be used as a source of healthy food for human regular diet

Effect of Padina tetrastromatica and Cymodocea serrulata using different methods extract on growth and pigments of black gram (Vigna mungo L.)

300-306To investigate the growth, percentage of germination, shoot and root length, fresh and dry weight along with photosynthetic pigments (chlorophyll a, b, and total chlorophyll) of Vigna mungo was analyzed by using seaweed (Padina tetrastromatica) SLF and seagrass (Cymodocea serrulata) SGLF extracts of seven days old seedlings. The seaweed and seagrass extracts were prepared by five different methods such as low temperature, boiling, autoclave, alcohol, and alcohol aqueous extracts with different concentration ( 0.5, 1.0, 2.0, 3.0, 4.0, and 5.0%). The results revealed that significant effect showed low temperature, autoclave, and alcohol aqueous methods of seaweed and seagrass extract preparation, the study suggested that field trial to assess the seaweed and seagrass fertilizer can be used as biofertilizer for better cultivation of Vigna mungo

Phytochemical and medicinal properties on Strychnos-nux-vomica (L)

Strychnos nux-vomica L. (Loganiaceae) is a deciduous tree that grows in tropical areas and is distributed throughout India and Southeast Asia. The dried seed of this plant S. nux vomica has been applied clinically in Chinese medicine for hundreds of years. S. nuxvomica is a non edible tree with a strong content of two poisonous alkaloids, strychnine and brucine. S. nux-vomica which belongs to the family loganiaceaalso called Kanjiram is a medium-sized tree. Other names of S. nux-vomica are Kanjiram, Kuchla, Kupilu.  Phytochemical analysis revealed the presence of alkaloid, carbohydrate, tannin, steroid, triterpenoid and glycoside in the extract. Seeds of Nux vomica used as nervine tonic, alexiteric, aphrodisiac, anthelmintic, digestive, purgative and stimulant. Detoxified S. Nux vomica seeds used in various Ayurvedic drugs like Agnitundi vati, Navjeevan Rasa and vishatinduka vati as an important ingredient. This study presents a review on the Phytochemical and Medicinal properties of S.nux vomica L

Phytochemical and Traditional uses on Acanthus ilicifolius (L)

Acanthus ilicifolius is a spiny herb found in mangrove of southern Thailand. It is also widely distributed in India and other tropical regions of Asia. The plant is reported to contain phytochemicals including alkaloid and wide range of glucosides  (lignan and phenylethanoid). In traditional medicine, the plant is used in the treatment of diseases ranging from snake bite to skin diseases. A. ilicifolius (sea holly) occurs in tropical Asia and Africa, through Malaya to Polynesia. It is a vine shrub or tall herb, up to 1.5 m high, scarcely woody, bushy, with very dense growth. Common names of which are holy leaved acanthus, sea holly and holy mangrove. A. ilicifoliusis abundantly available in freshwater ecosystem of Pichavaram mangroves located in southeast coast of India. The review analyses traditional medicinal usage, and phytochemical  investigations done on the A. ilicifoliusis medicinal plant

NUTRITIONAL AND ANTI-NUTRITIONAL ATTRIBUTES OF SOME UNDER–UTILIZED TUBERS

The wild edible tubers of Asparagus racemosus, Curculigo orchioides, Dioscorea bulbifera var. vera, Dioscorea oppositifolia var. dukhumensis D. oppositifolia var. oppositifolia, D. pentaphylla var. pentaphylla, D. tomentosa and Dolichos trilobus were analyzed for proximate and mineral composition, starch, vitamins like niacin, ascorbic acids and certain anti-nutritional factors. The tubers of D. oppositifolia var. dukhumensis contained higher quantity of crude protein. The tubers of A. racemosus and Dolichos trilobus contained higher amount of crude lipids. All the investigated wild tubers had a higher level of manganese content compared to ESADDI of infants, children and adults (NRC/NAS, 1989). The tubers of D. oppositifolia var. dukhumensis, D. oppositifolia var.  oppositifolia, D. pentaphylla var. pentaphylla and D. tomentosa were found to contain more starch. The amount of niacin were higher in the tubers of D. tomentosa, D. oppositifolia var.  oppositifolia and A. racemosus Anti-nutritional factors such as total free phenols, tannins and hydrogen cyanide were also analyzed. It was concluded that wild tubers analyzed are a viable food source

CHEMICAL EVALUATION OF RAW SEEDS OF CERTAIN TRIBAL PULSES IN TAMIL NADU, INDIA

Raw seeds of tribal pulses Dolichos trilobus, Entada rheedi, Mucuna atropurpurea, Rhynchosia cana, R. suaveolens, Tamarindus indica, Teramnus labialis, Vigna radiata var. sublobata and V. unguiculata subsp. cylindrica were investigated for their proximate composition, minerals, vitamins (niacin and ascorbic acid) and certain anti-nutritional substances (total free phenolics, tannins, L-DOPA and hydrogen cyanide were also analysed). The seeds of Mucuna atropurpurea, Tamarindus indica and Teramnus labialis had a higher content of crude protein than commonly consumed Indian pulses. The seeds were found to be a rich source of minerals like potassium when compared with Recommended Dietary Allowances (RDA) values (NRC/NAS, 1980)

The effect of daytime rain on the Indian Flying Fox (Mammalia: Chiroptera: Pteropodidae Pteropus giganteus)

Excessive water loss during the day due to heat stress in bats of the genus Pteropus appears to be inevitable, because these bats are exposed to direct sunlight.  Rain also affects the rest pattern of the Indian Flying Fox Pteropus giganteus during the day.  When rain occurred during the day, most of the bats hung in a slanting position and did not exhibit any movements.  After rain, they licked both ventral and dorsal surfaces of the wing membrane and scratched their body with their thumb claws.  They also licked the water droplets that remained on the leaves and branches of the tree.  Even though their rest had been affected by the rain the bats utilized the water droplets to quench their thirst, cool their body and clean their fur.  The construction of water reservoirs near Pteropus roosts will help to assure their long-term conservation. </div
