This study was conducted to highlight the antifungal activity of the essential oils of four local plants namely Lippia multiflora, Cymbopogon citratus, Hyptis suaveolens and Eucalyptus globulus on some germs found on rice, maize, cowpea and peanut seeds. . The health status of these seeds revealed the presence of fungi such as Aspergillus flavus, Aspergillus niger, Rhizopus, Bipolaris oryzae, Cladosporium sphaerospermum, Fusarium pallidoroseum, etc.The essential oils of Lippia multiflora and Cymbopogon citratus were effective at different concentrations on all fungal species. However, all oils showed antifungal activity. This suggests that the antimicrobial potential of these plants can be used to preserve the germinability of seeds.

Activité antifongique des huiles essentielles de quatre plantes locales sur quelques germes des semences de riz, maïs, niébé et d’arachide

SEA Tehi Bernard, SORO Yadé René, CISSE Mohamed, DOFFOU N’cho Marc, KOUASSI Alyne Aurélie,DOI: 10.24214/IJGHC/HC/8/1/00108.

Cette étude a été réalisée pour mettre en évidence l’activité antifongique des huiles essentielles de quatre plantes locales à savoir Lippia multiflora, Cymbopogon citratus, Hyptis suaveolens et Eucalyptus globulus sur quelques germes trouvés sur des semences de riz, maïs, niébé et d’arachide. L’état sanitaire de ces semences a révélé la présence des champignons tels qu’Aspergillus flavus, Aspergillus niger, Rhizopus, Bipolaris oryzae, Cladosporium sphaerospermum, Fusarium pallidoroseum, etc.Les huiles essentielles de Lippia multiflora et de Cymbopogon citratus ont été efficaces à différentes concentrations sur toutes les espèces fongiques. Cependant, toutes huiles ont montré une activité antifongique. Ce qui suggère que le potentiel antimicrobien de ces plantes peut être utilisé pour préserver le pouvoir germinatif des semences.  

Screening of Phytochemical and Phytonutrient contents of leaves of Erythrina indica

R.Priya and S.Maneemegalai,DOI: 10.24214/IJGHC/HC/8/1/00916

The present investigation was carried out to explore the phytochemical and phytonutrient contents of leaves of Erythrina indica since it possess medicinal value and used for treating many diseases in traditional medicine. The powdered leaf material of E. indica was assessed for the presence of carbohydrates, proteins, free fatty acids, β carotene, folic acid, nicotinic acid, vitamin E and vitamin C. Moisture content and ash content was also evaluated. Qualitative and quantitative analysis of phytochemicals were conducted in the ethanolic leaves extract of E. indica resulted in the presence of rich range of phytochemicals. Alkaloid was observed to be present in high concentration followed by phenols, flavonoids, tannins, steroids and saponins. The different biological activity of these chemicals establishes the overall medicinal activity of E.indica.

Cyperus scariosus R.Br. - An update

Paramjeet Cheema,DOI: 10.24214/IJGHC/HC/8/1/01726

Cyperus scariosus, a perennial herb plant native to India is an invasive weed with wide distribution. It remained to be an important ingredient of several prescriptions used in indigenous system of medicine to treat a variety of diseases including diarrhea, epilepsy, gonorrhea, syphilis and liver damage. Recent studies highlight its phytochemistry, bioactivity and therapeutic uses. Major chemical components of this herb are alkaloids, flavonols, glycosides, polyphenols, saponins, sesquiterpenoids and essential oil responsible for its claimed traditional importance as one of the potential medicinal herb. Cyperiol, the essential oil obtained on steam distillation of the rhizomes contains about 100 compounds, has its value in perfumary and account for the antibacterial, antifungal, insecticidal and ovicidal activity. Complete information regarding the plant species has been collected from various books and journals and internet databases. This communication aims to integrate all the information available on C. scariosus which may help academicians, agronomists, environmentalists, biological scientists and researchers to explore the potential of this commonly growing weed. Further the data generated would be useful for the pharmaceutical industry.

Investigation of Neem based mixed leaf extracts as natural pesticides to protect our Environment

Ashoke Hazra,DOI: 10.24214/IJGHC/HC/8/1/02633

Present paper investigates some natural pesticide which was environment friendly, biodegradable and also nontoxic. For these purpose Neem leaf, Lemon leaf, Indian Bay leaf (Tejpatta leaf) extracts were used. This study was continued on 45 days. Characterization of these leaf extracts were carried out by UV/Visible (Elico, 171, Mini spectro) spectroscopy. After 45 days it has been found that Mix leaf extracts show better result than the other three extracts. And also Lemon leaf extract shows medium level natural garden pesticides.

Pharmacognostic characterisation and development of standardization parameters for the quality control of Leaves of Jasminum mesnyi

Hayat M Mukhtar, Rohit Goyal, Hitesh Kumar,DOI: 10.24214/IJGHC/HC/8/1/03442.

Jasminum mesnyi is cultivated in tropical and sub-tropical region throughout the world; in India it is found mainly in Himalayan region. It is an evergreen shrub moves up to 2.5 m in height and grows like a climber or some time crawl on other plant. Plant contains several medicinally important chemical constituents like bitter glycosides, secoirridoids, flavonoids, phenolic compounds etc. Plant is reported to possess medicinal activities like anti-oxidant, anthelmintic, wound healing etc. The present study was carried out to establish a pharmacognostic standard of the leaves of Jasminum mesnyi by determining the pharmacognostical, physiochemical and toxicological parameters. The study has been conducted according to guidelines of World Health Organisation and Ayurvedic Pharmacopoeia of India. Water, alcohol, chloroform, petroleum ether soluble extractive value was found to be 11.6% w/w, 9.68% w/w, 4.2% w/w, 1.6%w/w respectively by hot method. Total ash, acid insoluble ash, water soluble ash, sulphated ash was found to be 3.5% w/w, 0.9% w/w, 1.1% w/w, 0.59% w/w respectively. Loss on drying, swelling index, fibre content, foaming index, bitterness value, tannin content was found to be 4.40% w/w, 0.6 cm, 6.78, Less than 100, 6700, 0.78% w/w respectively. Content of heavy metal and microbial count was found within the acceptable range. Preliminary phytochemical screening revealed the presence of carbohydrates, glycosides, phenolic compounds, flavonoids etc. The above studies may be useful for pharmacognostical study and standardization of the herbal drugs and for enrichment of Ayurvedic pharmacopoeia
