Phytochemical and Biological Studies on Some Medicinal Plants

Abstract

Biological studies on thirteen ethanolic plant extracts (Rosmarinus officinalis ,Ocimum basilicum , Moringa oleifera, Zingiber officinale, Curcuma longa, Nigella sativa ,Cinnamomum verum ,Salvia officinalis, Lepidium sativum, Foeniculum vulgare, Anethum graveolens, Ficus benghalensis and Cinnamomum camphora) revealed that four of them (Rosmarinus officinalis , Zingiber officinale, Cinnamomum verum and Cinnamomum camphora) were the best active against two bacterial species ; E. coli , S .aureus and one fungus species C. albicans. Also, their synergistic effects against E. coli, S. aureus and C. albicans were studied .So, the phytochemical studies were completed on these four plants. This study aimed to evaluate the chemical composition of the best active plant extracts. The chemical major content of Rosmarinus officinalis was eucalyptol (7.48%) , Zingiber officinale was gingerol (12.73%) , Cinnamomum verum was (E)-cinnamaldehyde (25.55 %) and Cinnamomum camphora was eugenol (27 .35%). The minimum inhibitory concentration (MIC) values varied from 0.625 to 2.5 mg/ml, for the S. aureus (gram positive bacteria) affected by Rosmarinus officinali, Zingiber officinale, Cinnamomum verum and Cinnamomum camphora. Respectively. C. albicans was the most effective microorganism by Cinnamomum verum and the least effective microorganism by Rosmarinus officinalis and Cinnamomum camphora. ethanolic extracts, as MIC ranged from 0.15 to 1.25 mg/ml.

Tropical Medicinal Plant Extracts from Indonesia as Antifungal Agents against Candida Albicans

“…Previous studies [63,64] reported a higher MIC and MFC of C. longa methanolic extract than ours. Meanwhile, MIC and MFC of Z. officinale Rosc from our study are higher than previously reported results [65,66].…”

Histomorphometric effects of energy drink consumption on pancreatic tissue of albino wistar rats.

“…Following the administration of caffeinated beverages, similar findings in hepatic and pancreatic tissues have been reported by Al Eyrani et al and Al Siddiqui et al respectively. 9,23 This occurrence is crucial to the body's inflammatory response to a substance that could be toxic.…”

“…Along with the functional issues, it also damages the organ's exocrine and endocrine components. 9,10 All the untoward effects on different body organs of the younger generation due to the growing consumption of caffeinated beverages in this age group need to be determined. Various studies have been done to demonstrate and explain the toxic effects of different ingredients of EDs on various body organs.…”
