The present investigation was aimed to study the antimicrobial potential of Tinospora cordifolia (Thunb.) Miers commonly known as "Giloy" which is used by the herbal practitioners for curing several ailments. The antimicrobial potential was explored by using solvent extracts of T. cordifolia stem aga inst clinical pa thogenic isola tes, i.e., S tap hyloco ccu s a ure us, Ba cillus ce reu s, Pseudomonas aeruginosa, Streptococcus pneumoniae and Yersinia pestis. Extraction was carried out by cold percolation method, using various solvents, viz., chloroform, acetone, methanol and water. Among all, the chloroform and acetone extracts of T. cordifolia showed maximum activity against S. aureus (18.22 mm at 4 mg/ml). The minimum inhibitory concentration (MIC) of solvent extract of T. cordifolia was 6 mg in case of S. aureus. It was found that extremely small quantity of crude extract of T. cordifolia was sufficient to inhibit the growth of pathogenic microbes and it was quite comparable to the positive control used in many cases. These encouraging results can be taken further to purify and characterize the plant extracts and to check their antimicrobial activity against the pathogenic bacteria so as to utilize the pharmacological potential of the plant extract at higher scale after extensive R & D efforts.

Salah satu masalah dalam budidaya bibit Falcataria mollucana di persemaian adalah serangan hama Pseudococcus calceolariae. Serangan hama tersebut menghambat pertumbuhan bibit dan pada akhirnya menyebabkan kematian bibit. Beberapa tanaman yang ditemukan di lapangan, seperti Swietenia macrophylla, Azadirachta indica, Morinda citrifolia, dan Carica papaya, memiliki senyawa bioaktif yang dapat digunakan sebagai pestisida botani. Tujuan dari penelitian ini adalah untuk mengetahui jenis ekstrak daun yang efektif dalam mengendalikan hama P. calceolariae pada bibit F. mollucana berdasarkan penurunan insiden dan keparahan serangan P. calceolariae. Hasil penelitian menunjukkan bahwa ekstrak daun S. macrophylla, A. indica, M. citrifolia, dan C. papaya efektif dalam mengendalikan hama P. calceolariae pada bibit F. mollucana. Ekstrak daun A. indica memberikan penurunan insiden dan keparahan serangan P. calceolariae yang lebih tinggi dibandingkan dengan ekstrak daun lainnya, yaitu sebesar 80,13% dan 57,69%.
