Pavonia odorata Willd. belonging to the family Malvaceae is well known for curing a variety of diseases. This study deals with the Pharmacognostical and phytochemical evaluation of whole plant of Pavonia odorata Willd. The plant is widely used as a cooling, diaphoretic, diuretic, and demulcent. It is also prescribed as an astringent and tonic for fever, inflammation and hemorrhage. Pharmacognostical studies include macroscopic, microscopic and physicochemical evaluation of the whole plant. The transverse section of root, stem and leaves were performed. Physicochemical constants showed the values of total ash (4.45%), acid insoluble ash (0.754%), water soluble ash (6%), sulphated ash (6. 5%), nitrated ash (1.65%), hot extraction(10.22%), water soluble extractive (9.2%), ethanol soluble extractive (4.8%), ether soluble extractive (1.2%), loss on drying (25%), swelling index(1) and mucilage content(0.25%) w/w. The preliminary phytochemical screening of the alcoholic extract showed presents of alkaloids, phenolic compounds, steroids, mucilage and flavonoids. The study helps in the development of standard parameters of the plant which help the identification and authentication of the plant. Keywords: Pavonia odorata Willd., Pharmacognostical, phytochemical evaluation, Medicinal plant drugs, ethnomedicine.

The lemon grass, Cymbopogon citratus (DC) Stapf, is an important species of Poaceae family commonly used in the folk medicine in many countries. The aim of this study was to investigate the cytotoxic and genotoxic effects of aqueous extracts from C. citratus leaves on Lactuca sativa (lettuce) root tip meristem cells by cytogenetic studies that have never been done before for lemon grass extracts. For this, lettuce seeds were treated for 72h with different concentrations of lemon grass aqueous extracts (5; 10; 20 and 30 mg/mL). The percentage of germination, root development and cellular behavior were analyzed, and the results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce. The extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.

This study deals with the Pharmacognostical physicochemical and phytochemical evaluation of the whole plant of Piper longum L. Pharmacognostical studies include macroscopic, microscopic and physicochemical evaluation. Physicochemical constants showed the values of total ash (10.8%), acid insoluble ash (1.3%), water soluble ash (3.2%), sulphated ash (12%), nitrated ash (1.85%), hot extraction (11.2%), water soluble extractive (4.8%), ethanol soluble extractive (12.4%), ether soluble extractive (5.6%), loss on drying (29%), swelling index (0.33) and mucilage content (0.8%) w/w. The preliminary phytochemical screening of the alcoholic extract showed presents of alkaloids, phenolic compounds, tannins, mucilage, starch, steroid and flavonoids. This study helps to development of different standard parameters of the plant which help the plant identification and authentication.

Background: Depression is a common psychiatric disorder. Drug therapy is the cornerstone in the management of depression. Anti-depressants are associated with many unwanted side-effects. Thus, various herbal products have been tried. The advantages of herbal treatments include safety, cheap and acceptability due to their traditional values. The objective of the present study was to evaluate the anti-depressant activity of Cymbopogon citratus (lemon grass) in albino mice and to compare with Imipramine. Methods: 30 Swiss albino male mice weighing around 25-30 g were divided into 5 groups (n=6). Group I (Control) mice were given normal feed and water, Group II (Standard) received 20 mg/kg T. Imipramine orally, Group III (Test-1) received 5 mg/kg aqueous extract of C. citratus (lemon grass) orally and Group IV (Test-2) received 10 mg/kg C. citratus (lemon grass) orally, and Group V (Test-3) received both T. Imipramine (10 mg/kg) and C. citratus (10 mg/kg) orally. Duration of immobility was observed for last 4 mins of total 6 mins period in groups 1-5 by tail suspension test on 1st, 8th and 15th day.Results: Duration of immobility recorded in seconds was analyzed by one-way analysis of variance, followed by Tukey’s post-hoc test Conclusion: Lemon grass has a significant antidepressant effect. Combined effect of lemon grass at 10 mg/kg and imipramine 10 mg/kg is not synergistic.

Cymbopogon citratus, widely known as lemongrass is used as folk medicine for several disease conditions. Preliminary phytochemical screening of the essential oil extract of C. citratus revealed the presence of various bioactive compounds like alkaloids, avonoids, saponins, tannins and phenolic compounds in the aqueous extracts. Essential oil was extracted from C. citratus leaves and its chemical constituents were identied by Gas Chromatography-Mass Spectrometry (GC-MS).
