On the other hand, there is an increasing demand of antioxidant, calories and protein rich quality, healthy, nutritious food by the health conscious modern people. Underutilized vegetable crops are important source of valuable nutritional and medicinal component. These are cheaper and affordable than the exotic imports. Exploitation of these wild resources is an important way of income and food, especially for the poor farmers who are also underemployed.

One of the most common diseases of old age in modern societies is glaucoma. It is strongly connected with increased intraocular pressure (IOP) and could permanently damage vision in the affected eye. As there are only a limited number of chemical compounds that can decrease IOP as well as blood flow in eye vessels, the up-to-date investigation of new molecules is important.

  • A. Primary Metabolites B. Secondar Metabolites
    TAXONOMIC EVIDENCES FROM PHYTOCHEMISTRY Plant produces many types of natural products and quite often the biosymthetic pathways producing these compounds differ from one taxon to another. These data sometimes have supported the existing classification or in some instances contradicted the existing classification. The use of chemical compounds in systematic and taxonomic study has created a new branches of biological science – Chemosystematics or Chemotaxonomy or Biochemical systematic. The natural chemical compounds of taxonomic use can be divided as follows – A. Micromolecules – Molecules having molecular weight 1000 or less. Micromolecules are divided into two major groups – 1. Primary metabolites- involved in vital metabolic pathway, usually of universal occurrence , e.g., Citric acid, Aconitic acid , amino acids, sugars etc. 2. Secondary metabolites – These are by-product of metabolism. They usually perform non-vital functions and not universal in occurrence therefore less widely spread among plants. It includes – non-protein amino acids, terpenoids, flavonoid compounds and other phenolic compounds, alkaloids, cyanogenic compounds, glucosinolates, fatty acids, oils, waxes etc. B. Macromolecules- Molecules having molecular weight 1000 or more. Macromolecules are of two types – 1. Semantids – These are information carrying molecules and can be classified into 3 categories – Primary Semantids (DNA), secondary Semantids (RNA), and Tertiary Semantids ((Protein). The utilization of studies on DNA and RNA for understanding of Phylogeny has established a new field of study the molecular systematic. The results obtained from Protein taxonomy are largely divisable into four main headings – Serology, Electrophoresis, amino acid sequencing, and isoelectric focussing. 2. Non-Semantids macromolecules – compounds not involved in information transfer – Starch, Celluloses etc. Apart from these there are some compounds that are directly visible such as crystals – Raphides etc.

  • 6.Aptosimum Literature Chapter 2
    Chapter 2 Phytochemistry of Aptosimum procumbens 2.1 Introduction Aptosimum procumbens Burch (= A. depressum) of the tribe Aptosimae belongs to the Scropulariaceae sensu stricto family of the order Lamiales.1 Scrophulariaceae is one of the largest plant families and is comprised of about 190 genera and 4000 species. Plants from this family are mostly woody herbaceous shrubs and are found predominantly in the temperate regions of the world.2 They are distinguished from related families with relative ease, but many plants are assigned to this family because they lack distinguishing characteristics that would place them in the other specific families. Therefore, Scrophs share some of the characteristics of plants of related families and this may negate the possibility that Scrophulariaceae is a distinct clade. As a result of this, there are doubts as to whether the family is monophyletic or should rather be classified as polyphyletic or paraphyletic.1 Phytochemical investigations can provide a valuable input with regards to the chemotaxanomical studies of this family. A. procumbens (Fig. 1) is mainly referred to as “carpet flower” but shares a variety of vernacular names such as “brandbossie/blare”, “Karoo violet/flower” and “kankerbos” with other related species of Aptosimum. A common name is given to a plant based on certain characteristics of the plant. A. procumbens is a prostrate mat-forming species hence the name “carpet flower”. The plant has strong woody procumbent stems with short lateral, dense leafy and floriferous branches. Another characteristic feature is the violet trumpet-like flowers that bloom in the summer or after rainfall (hence the name “Karoo violet”).

These compounds in their aglycones and glycosylated forms exist in nature to contribute to mechanisms related to plant defenses and diverse plant-animal interactions. Recent studies have also shown that iridoids and other structurally related monoterpenes display a vast array of pharmacological effects that make them potential modulators of the Alzheimer’s disease (AD). This review critically evaluates the therapeutic potential of these natural products by assessing key in vitro and in vivo data published in the scientific literature. Mechanistic approach of scrutiny addressing their effects in the Alzheimer’s brain including the τ-protein phosphorylation signaling, amyloid beta (Aβ) formation, aggregation, toxicity and clearance along with various effects from antioxidant to antiinflammatory mechanisms are discussed. The drug likeness of these compounds and future prospects to consider in their development as potential leads are addressed. Keywords: monoterpenes; iridoids; Alzheimer’s disease; amyloid beta; drug likeness; multiple mechanisms 1. Introduction Alzheimer's disease (AD) is one of the most prevalent age-related diseases mostly affecting the elderly population. Of the estimated 5.5 million Americans with AD in 2017, 5.3 million comprising about 96% of the patients’ population, were 65 years of age or older [1].
