Screening of Indian Plants for Biological Activity: Part VII - Spermicidal Activity of Indian Plants

Extracts of about 1600 Indian plants were tested in vitro on rat and/or human spermatozoa. Thirty extracts showed spermicidal activity in rat and of these 16 caused instantaneous immobilization of human spermatozoa.

Screening of Indian Plants for Biological Activity : Part VIII

Extracts of 644 plant materials were screened for tannins and 204 extracts gave a positive test. Quantitative evaluation of tannins in positive extracts showed that 16 contained appreciable quantities. Insecticidal activity was tested against Musco domestica and Tribolium casteneum in 162 extracts and was confirmed in 17 and 4 extracts respectively.

Screening of Indian Plants for Biological Activity : Part IX

Two hundred and ninety three botanically identified plant materials have been tested as 50% ethanol extracts, for a wide variety of biological activities including antifertility, anticancer, chemotherapeutic and pharmaceutical activities. Biological activity has been confirmed in fractions of 40 of these extracts.

Screening of Indian Plants for Biological Activity: Part X

Two hundred eightythree botanically identified plant species have been tested as 50% ethanol extracts, for a wide variety of biological activities including antifertility, anticancer, chemotherapeutic and pharmaceutical activities. Biological activity has been observed in 143 of these extracts. The biological Activity has been confirmed in the fraction of 35 extracts and anticancer activity in the extracts of 23 plant species.

Screeningof Indian Plants for BiologicalActivity-Part XI

Alcoholic extracts of two hundred and ninety two botanically identified plant species have been tested for a wide variety of biological activities including chemotherapeutic and pharmacological activities. Biological activities have been confirmed in fractions of 46 of these extracts. Follow-up studies have been carried out in some plants with confirmed activity. The active principles and results of these studies have also been reported.

Screeningof Indian Plants for Biological Activity :Part XII

Alcoholic extracts of 295 botanically identified plant materials from 267 plant species have been tested for a wide variety of biological activities including chemotherapeutic and pharmacological screenings. Biological activities have been confirmed in fractions of 64 of these extracts. Follow-up studies have been carried out in some plants with confirmed activity. The active principles and results of these studies are reported.

Screening of Indian Plants for Biological Activity : Part XIII

Biological activities have been confirmed in 51 fractions of the extracts. Follow-up studies have been carried out in some plants with confirmed activity. The active principles and results of these studies are reported.

Screening of Indian plants for biological activity : Part XIV

Alcoholic extracts of 300 botanically identified plant materials from 275 plant species have been tested for various biological activities including chemotherapeutic and pharmacological screenings. Biological activities have been observed in 111 extracts. Follow-up studies have been carried out in some plants with confirmed activity. The active principles and results of these studies are reported.

Screening of Indian plants for biological activity: Part XV

Alcoholics extracts of 266 botanically identified plant materials from 222 plant species have been tested for various biological activities including chemotherapeutic and pharmacological screenings. Biological activities have been observed in 89 extracts. Follow-up studies have been carried out in some plants with confirmed activity. The active principles and results of these studies are reported.

Screening of Indian plants for biological activity: Part XVI

Alcoholic extracts of 288 of plant materials from 199 plant species have been tested for various biological activities including chemotherapeutic and pharmacological screening. Biological activities, ranging from moderate to good degree, have been observed in 61 plants extracts. Follow up studies have been carried out in these extracts and some of them have shown moderate degree of activities at this Institute. However, none of the extracts was found to be good enough for further development. Results of the present studies, alongwith chemical investigations on different species of similar genera which were screened earlier, are also discussed.
