Chemical analysis of Tamirapparpam  was carried out. The parameters evolved for laboratory made medicine can be used for fixing standards.

This paper describes the ethnobotanical importance of 6 Rutaceous plants common in Andhra Pradesh. For each plant its popular name/local name and manner of use are described. Data are based on personal survey, observation and discussion with chenchu, Yanadi, Erukala and sugali tribes of this area.

Amoebiasis is a problem in northern India. In Ayurveda several herbal drugs are mentioned, to be used for controlling the amatisara (amoebiasis) but none of the drug are found having potent effect to iradicate the disease. In ancient literature kutaj (Holarrhena antidysentrica) is mentioned in commonest was for controlling the disease this plant is prevalently found in Himalayan and vindhaya area. It is very effective for relieving amoebiasis. By seeing its theuraptic importance we have tried to standardize the compound in whole with special reference to kutaj. The detail composition and method of preparation of drug with its therapeutic effect will be narrated during the time of workshop.

Crude enzyme extract obtained from the petioles of the plant piper betel- Bengal variety as been evaluated for various physico-chemical studs such as estimation of protein content, thin layer chromatography, optical activity and tests for the presence of thiol groups, disulphide and peptide linkages and the results are discussed.

The aqueous extract of flowers of I. coccinea  was evaluated for its cytotoxic and mutagenic effects on the meristematic cells of onion root tip. The percentage of abnormalities was found to increase with the increase in the concentration of the extract from 20 to 60 mg/ml. With 80 mg/ml completed arrest or total inhibition of cell division was observed. The major abnormalities were unprinted chromosomes at metaphase. Stickiness and clumping of chromosomes were induced by higher concentrations of the extract. Sticky anaphase bridges and formation of micronuclei were induced at the highest concentration (80mg/ml) tried. The significance of these abnormalities is discussed in detail. The results point to the potential use of the aqueous extract of flowers of I. coccinea  in the chemotherapy of cancer.

The paper deals some ethnomedicinal plants of Bihar which used as antidote in traditional phytotherapy.

The rhizome of Nelumbo nucifera  Gaertn (fam. Nymphaeaceae) was studied to fix the parameters for pharmacognostical standards. The present investigation deals with the macro and microscopically characters of rhizome along with studies on some physical constants, behavior of powdered rhizomes on treatment with different chemical reagents and florescence characteristics on exposure to U.V light, which would help in identification of the drug.

In the present study we report some physico-chemical standards for Karpooradi taila  which is a medicated oil used for the treatment of "Varrthavikaram". The physicochemical standards and the Thin Layer chromatographic pattern can be used as a finger print standard for Karpooradi taila .

The present ethnobotanical exploratory study embodies the folk medicinal uses of certain important medicinal plants by tribals of bastar district in Madhya Pradesh state of India. Twenty seven medicinal plants form diverse families have been covered being therapeutically used against different diseases such acidity, debility, diabetes, male and female weakness, fistula, migraine and skin diseases etc. How the tribal folks consider the mode of drug administration and application in different ailments has been ailments has been elaborately emphasized.

Berberis asiatica  Roxb. Ex. Dc., non Griff. Belongs to the family berberidaceae commonly occurring in the dry outer Himalaya, Assam etc. Roots along with stem bark s a reputed drug in Ayurvedic medicine contain several alkaloids. 50% Ethaolnic extract of roots reported to posses anti-cancer activity. The present study examines the antitumour effect of ethanolic root extract (BRE) against Dalton's lymphoma ascites tumour cells and solid tumour in swiss albino mice, A significant enhancement of mean survival time of BRE treated tumour bearing mice was found. Oral administration of BRE reduced the solid tumour induced by DLE and restored the altered haematological parameters to normal.

Volatile oil of Psidium guajava  leaves obtained by steam distillation was given orally to study its effects on the exudation and proliferative phases of the inflammatory reaction, using technique of carragenin induced paw edema and cotton pellets in male albino rats. The anti inflammatory activity as compared with ketorolac tromethamine. In carragenin induced edemas,. 0.8ml/kg of the volatile oil ad anti-inflammatory activity as that of ketorolac tromethamine. The oil was also found to be potent in cotton pellet granuom studies. Preliminary investigation revealed that the volatile oil fraction consist sesqueterpene which may be responsible for its anti inflammatory activity.

Balarishta  and Dhanvantara  gutika  are ayurvedic medicines prescribed in different diseases including rheumatism. These medicines were screened for anti-inflammatory activity against cotton pellet induced granuloma in albino rats. There was significant reduction in cotton pellet weight by both the tested drugs. Dhanvantara gutika  significantly reduced the ascorbic acid in adrenal. Acid phosphatase, GPT and GOT activities were significantly reduced by Balarishta, Dhanvantara gutika and phenyl butazone in liver. In the serum acid phosphatase activity was significantly reduced by both the tested drugs and phenul butazone while GPT activity was lowered by Balarishta  alone and GOT activity was reduced by Balarishta and Dhanvantara gutika . Phenyl butazgone reduced the activity of GPT.

The n-butanol extract of the leaves Polyscias fruticosa  (L) Harms (Araliaceae) was tested for its anti-inflammatory activity plethismometrically in egg white induced paw oedema in rats, antipyretic activity and analgesic activity by writhing method phenyl butazone, paracetamol and aspirin were used as positive controls for anti-inflammatory, antipyretic and analgesic activity screening studies receptivity. It as observed that the n-butanol fraction mainly contains terpenoid type of saponins and designated as NBES fraction- (n -butanol extract containing saponins). Molluscicidal screening studies proved the effectiveness of NBES to control certain kind of snails which are considered as the primary host of fluke worms.
