It contains several active constituents, and the most important bioactive compounds are triterpenoid saponins, including asiaticoside, centelloside, madecassoside, and asiatic acid. It possesses anti-leprotic, anti-viral, anti-bacterial, anti-tumor activities. Due to its medicinal importance, this plant is being overexploited and to conserve this plant, it is necessary to micropropagate this plant in a laboratory with high biomass...

The present study was investigated the phytochemical properties, analgesic and cytotoxic activities of the ethanolic extract of Lagerstroemia speciosa (L.) Pers. fruits (Family-Lythraceae). Phytochemical screening of the ethanol extract of fruits of L. speciosa showed the presence of Steroids, Tannins, and Saponins types of compounds. The pharmacological interest of these compounds encouraged to check L. speciosa Pers. for possible analgesic & cytotoxic activities. The crude extract at the dose of 500 mg/kg body weight exhibited moderate action against acetic acid-induced pain in mice significantly (p<0.01), where percentage of protection was found 55.21% while the standard drug diclofenac’s percent of protection was found to be 84.37% at a dose of 25 mg/kg body weight. The extract showed potent cytotoxic activity to brine shrimp, and LC90 was found at the dose of 100 µg/ml as well as LC50 was 60 µg/ml. The obtained results must help use this plant in traditional medicine and its further...

The current study was performed to study the antibacterial effects of solvent (ethanol, methanol, chloroform, hexane, acetone, petroleum ether) and aqueous extracts of lima bean, horse gram, and jack bean. The phytochemical studies performed on the extracts revealed the presence of alkaloids, steroids, triterpenoids, flavonoids, tannins, phenols, glycosides, and saponins. The antibacterial activity of these extracts was examined using agar well diffusion method. The extracts were studied for activity against pathogenic bacteria, namely P. syringae, E. coli, B. subtilis, E. faecalis, S. aureus, S. typhi, B. cereus, P. aeruginosa. The activity of the extracts against bacterial proliferation was estimated by measuring the zone of inhibition. The highest antibacterial activity among all the extracts tested and all the seeds involved in this study, the ethanol extract of horse gram has exhibited the maximum antibacterial effect against E. coli (12.0 ± 0.29), E. fecalis (11.0 ± 0.29) and B. substilis (10.0 ± 0.34). The results indicate that all three seeds in the discussion here show high potential for commercialization as antibacterial...

Liver is a vital organ play a major role in the metabolism and excretion of xenobiotics from the body. Liver injury or liver dysfunction is a major health problem that challenges not only health care professionals but also the pharmaceutical industry and drug regulatory agencies. Modern medicine has provided us many drugs that alleviate liver diseases but compared to it herbal medicine; herbal is preferred because they are cost-effective and considered to be a safe approach for treatment with minimal side effects. Herbal medicines have been used in the treatment of liver diseases for a long time. Several herbal preparations are available in the market. Many herbs have been proven to be efficient as hepatoprotective agents while many more are claimed to be hepatoprotective but be deficient in any such scientific substantiation to support such claims. Clinical research in this century has confirmed the efficacy of several plants in the treatment of liver disease. Hence, this review article contributes to the knowledge of reported indigenous plants, which are prevalent...

This paper deals with the concept of design and implementation of a low-cost model of an arms control moving chair using ATmega8.This moving chair can move forward, backward, left, and right. This is done with the movement (tilt) of the accelerometer, and the chair stops when there is no movement of the accelerometer. The values of the three-dimensional axis of the accelerometer can be varied and adjusted. The programming has been done through AVR compilers and burned into the ATmega8.The ATmega8 receives the information from the accelerometer and transmits it back via RX and TX pins.ATmega8 has also been interfaced to motor driver IC-L293D, wherefrom the connections go to two motors to drive the wheels of the chair. This model has been successfully implemented at a low cost, and it will benefit physically challenged persons, especially with the poor...
