A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield was reduced with wider row spacing of 360 cm or 75cm. However, the quality of oil as measured by the menthol content (71'0 – 72'3% was not affected by planting time as well as spacings.

The stability of Eazmov capsule in accelerated condition ie by exposing it to the temperature at 45°C and 40°C with 75% relative humidity was studied. The samples were periodically anallysed upto six months for their organoleptic characteristics, assay of active plant ingredients and the DPTLC finger printing and their peak area analysis, which were found to be stable/ consistent during the period of study. The change in quantifiable components was within 90% of the initial amount, indicating e stability of product for more than three years at room temperature.

The aqueous and ethanolic (90%) extract of the leaves of M.Oliera Lam (Fam: Moringaceae) were studied for their anti inflammatory action in ale albino rats. Two extracts exhibited maximum action within two hours of challenge. The aqueous extract sowed significant (P<0.01) odema suppression similar to that of Ibuprofen at the first hour of carrageenan injection. The results confirms the folkers claim of the plant.

The chloroform and alcohol extracts of e plats were screened against six bacteria viz staphylococcus aureus, Escherichia Coli, proteus mirablis, salmonella typhimurium, Pseudomonas aeruginosa and Klebsiella a aerogenes. Benzene-ethyl acetate (4:1) eluate of chloroform extract sowed activity against E.Coli, S.typhimurium and P.aeruginosa. The nbutanol extract of alcohol extract was active against P. mirablis and S. typhimurium. A phenolic compound isolated fro the above fraction exhibited activity against P. mirablis only.

The Macroscopic character of the leaves ash values, extractive values, behaviors on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different chemical reagents of the powdered leaves of ficus racemosa Linn (fam. Moraceae) were studied to fix some pharmacognostical parameters. Preliminary phytochemical studies on different extractives of the leaves were also performed. These studies will help in future for identifying this plant for further research.

Oral feeding of 50% EtOH extract of Curcuma longa to male rats at the dose of 1gm/kg body weight caused significant reduction of serum cholesterol, triglycerides and phospholipids (P≤0.01 to 0.001). Whereas the SGOT levels aware not reduced significantly. Fertility test showed 80% negative result. The negative fertility results reflects the arrest of spermatogenesis and depletion of androgen level. Further Curcuma longa reflects antispermatogenic nature.

The investigations were carried out on collations of the herb made from natural habitats with altitudes ranging from 1500 m to 2700m. the material was subjected to chemical screening which revealed a great deal of variation ranging from 0.75 percent to 1.14 per cent wit respect to bitter content which is a pharmaceutically important component of this plant. Besides this observations were also recorded on the effect of root length and root thickness on the yield of bitter principles, observations recorded on soil parameters did not reveal any significant effect on the bitter content production except soil pH.
