EFFECT OF LEAD (PB) ON PHYSICOCHEMICAL CHARACTERISTICS OF ARTEMISIA ANNUA L

Abstract

Artemisia annua L., often known as sweet wormwood, sweet Annie, sweet sagewort, and annual wormwood, is a widespread species of wormwood that originated in temperate Asia but has since spread naturally around the world. It is a member of the Asteraceae family. Chinese medicinal plant Artemisia annua L.is renowned for its antiplasmodial, antirheumatic, and anticancer effects. Currently, Artemisia annua  L.is the source of artemisinin and semi-synthetic artemisinin derivatives, such as dihydroartemisinin, artesunate, artemether, and arteether, which are used to make combination therapies (ACTs, or artemisinin-based combination therapies) for the treatment of malaria. This study focuses on how lead (Pb) affects Artemisia annua L. physiochemical and bioactive characteristics. Effects of lead the variables that were examined—carotenoids, stomatal conductance, chlorophyll content, and photosynthesis—were all impacted by lead concentrations in various ways. For plants, animals, and humans alike, lead is an extremely dangerous environmental pollutant. The presence of Pb as an impurity in fertilizers over a long period of time is another factor in its occurrence in fields. Pb is actually present in many different environments, such as the soil, water, air, fertilizers, and so on.  The results also showed that at various lead concentrations, germination percentage, shoot length, root length, leaf yield, and fresh weight decreased. In the plant treated with various doses of lead, the accumulation of CA activity, proline content, and CAT activity, among other things, was reduced.
