For a long period of time, plants have been a valuable source of natural products for maintaining human and animal health. The use of plant compounds for pharmaceutical purposes has gradually increased worldwide. This is because there are many bioactive constituents in plants which hinder the growth or kill microbes.

ABSTRACT Background: In diabetes mellitus, hyperglycemia causes oxidative stress that enhances the production of free radicals. The presence of higher levels of malondialdehyde (MDA) indicates the rise of free radicals. On the basis of its role as an antioxidant that binds free radicals and reduces the level of malondialdehyde (MDA). Soursop leaf can act as an antidiabetic agent. This study aimed to examine the efficacy of soursop leaf extract (Annona muricata L.) to decrease the level of MDA level in alloxan-induced diabetic rats (Rattus norvegicus). Subjects and Method: This was an experimen

Abstract:
Adulteration of ginkgo leaf extracts with extracts from flavonol-rich extracts from sources such as Japanese sophora is well documented in the literature. The partial or complete substitution of ginkgo extracts with flavonol-rich ingredients, or highly purified flavonoids (e.g., quercetin or rutin) from other sources (Table 1) was documented as early as 2003, and has been evidenced in over 20 peer-reviewed publications since. This Laboratory Guidance Document (LGD) presents a review of the various analytical methods used to differentiate between authentic ginkgo leaf extracts and ingredients c

Abstract:
Construction contractors often claim extra compensation associated with horizontally directionally drilled (HDD) pipeline installations is needed when drilling in rock. These claims result from HDD contractors' allegations that rock properties experienced during construction are significantly different from the properties on which the contractors' bids were based. This report provides information and recommendations that improve exploration and testing methods for assessing the drillability of rock to be encountered on HDD pipeline installations. These improvements will lead to a better unders
