Preliminary phytochemical tests played a significant role in finding and locating chemical constituents which are source of pharmacologically active principles. By consider the medicinal importance of tuber of Acorus calamus, flower of Senna alata and fruit of Solanum torvum, the present study was designed to screen the phytochemical constituents present in such plant parts preliminarily. The phytochemical analyses were conducted by employing standard methods to detect the presence/absence of alkaloids, carbohydrates, flavonoids, glycosides, phenols, phytosterols, proteins, saponins and tannins. The results of present study revealed that alkaloids were found to be present in all the three plants analyzed and all the three solvents extracted, whereas, glycosides and phenols were absent. The acetone extract of Acorus calamus and Solanum torvum showed the presence more number of phytochemicals (4 each) and petroleum ether extract of Senna alata and Solanum torvum revealed the presence of only one compound. The potential active principles of the detected compounds should be quantified and pharmacologically evaluated. Keywords: Preliminary phytochemical analyses, Acorus calamus tuber, Senna alata flower, Solanum torvum fruit.

Justicia gendarussa Burm .f. (family Acanthaceae) which is also known as willow-leaves and commonly known as Nili-Nirgundi, it is very commonly found nearby to China and its availability is very common in larger parts of India and Andaman islands. Traditionally it is used to treat various sorts of disorders such as wound healing, anti-inflammatory, anti-oxidant, antiproliferative, anti-arthritic etc. Justicia gendarussa is one of the crucial herbs which has been used in the Ayurveda. Majorly leaves parts of the plant shows the pharmacological activity but the root of the plant Justicia gendarussa is also have the important medicinal values. A large variety of pharmacologically active constituents i.e., alkaloids, flavonoids, saponin, carbohydrates, steroids, triterpenoids, carotenoids, aminoacids, tannins, phenolics, coumarines and anthaquinones are also present in this plant and they makes the plant pharmacologically important. The activity of the plant is also dependent on the solvent which is used for the extraction the various vital chemical constituents. The different- different parts of the plants having the different medicinal values also differ in the chemical values. This review is not only focused on the essential phytochemical constituents which is available in the plant but it also explains their necessary medicinal value to shows the essential biological action and phytopharmacological actions of various parts of the plant.

Plant Growth Regulation

Some chemical compounds in petroleum ether extract ofMikania micranthaH.B.K. can strongly influence seedling growth ofPhaseolus radiaus. In this study, we provide evidence that the chemical compounds in active fraction chromatographed on normal phase silica gel columns from petroleum ether extract ofM. micranthahave strong activity to promoteP. radiaustaking root. But meanwhile, these chemical compounds could be inhibitors forP. radiausroot growth. Two main chemical constituents, α-Bisabolol and Eudesma-5,11(13)-dien-8,12-olide, in the active fraction were confirmed by GC-MS analysis.

Further examination of the bark of Harpullia pendula has led to the isolation, from the light petroleum extract, of stigmasterol; from the ether extract, of a new compound, 15α,16α,22α,28-tetrahydroxy-olean-12- en-3-one, together with the known triterpenes A1-barrigenol, camelliagenin A and 22α-hydroxyerythrodiol. From the acetone extract of the bark and the leaves quebrachitol has been obtained.

The Gas Chromatography– Flame lonization Detector (GC-FID) method was employed in this study to evaluate the phytochemical constituents of both the aqueous and petroleum ether extracts of phyllanthus amarus leaves. Preliminary phytochemical screening showed the presence of Alkaloids, Flavonoids Glycosides, Phenols, Saponins, and Tannins. Further analysis revealed a total concentration of Phenol as 82.95mg/100g (4.46%) in the aqueous extract, Tannins 722.77mg/100g(38.82%),Alkaloids was 466.82mg/100(25.07%) while in the petroleum ether extract, Flavonoids was 472.59mg/100g (29.50%), Saponins 12.60mg/100g (0.79%) and Glycosides 18.63mg/100g (1.16%). These results are suggestive that P.amarus is endowed with phytochemicals that contains therapeutic potencies which support its use as traditional remedies for the treatment of variety of ailments.

Abstract Medicinal plants have several therapeutic properties; they have been used for a long time to treat different diseases. Lantana camara L. has been widely used by man for healing these diseases. In this study, four leaves extracts of L. camara were subjected to preliminary phytochemical screening to determine the presence and/or the absence of phytochemical constituents; In addition, they were tested for hemolytic activity on human erythrocytes. This activity is performed using the UV-Vis spectrophotometer method at 520 nm and at five different concentrations (125 µg/ml, 250 µg/ml, 500 µg/ml, 750 µg/ml, and 1000 µg/ml). The phytochemical screening showed the presence of various phytochemical groups such as phenolic compounds, saponins, sterols, tannins, flavonoids, reducing compounds and the absence of alkaloids in the four extracts. These same extracts showed average hemolytic activity sequentially: chloroformic extract, petroleum ether extract, aqueous extract and then methanolic extract. This activity is dependent on the concentration of the extract.

An experiment has been conducted to find out the toxic effect of acetone extract of Sapium indicum seed, petroleum ether extract of Thevetia neriifolia seed kernel and Jatropha gossypifolia seed on the fecundity and fertility of Tribolium castaneum and Tribolium confusum. The results indicated that all the treatments significantly (P < 0.001) reduced the fecundity and fertility of both the insect species. However Jatropha gossypifolia seed extract did not reduce significantly the fertility of Tribolium castaneum in comparison with the control but a decline of fertility was observed with the increase of dose of treatment.
