physical form and pattern of built environment in a city is the outcome of prevalent planning and design standards and building regulations. Many common issues of built environment are the consequence of existing building regulations in that settlement as building regulations are borrowed from other cities and adopted from one place to another across the country.
Driven by a plethora of external and internal influences, the construction industry has independently embraced lean principles and green initiatives. Prima facie significant synergies have been reported between these two paradigms. It is foreseen that when tapped and adopted in unison, these paradigms may yield additional benefits for the construction projects.
The flavonoids contained in Euphorbia neriifolia leaves were extracted, identified and characterized. Direct and sequential soxhlet extraction and its concentrated fractions were subjected to thin layer chromatography and high performance thin layer chromatography. The results showed that maximum yield of the flavonoid (6.53 g) was obtained from ethanolic extract.
Medicinal plants are a rich source of bioactive phytochemicals or bionutrients. Studies carried out during the past 2– 3 decades have shown that these phytochemicals have an important role in preventing chronic diseases like cancer, diabetes and coronary heart disease.
The traditional medicine involves the use of different plant extracts or the bioactive constituents. This type of study provides the health application at affordable cost. Secondary metabolites are responsible for medicinal activity of plants. Hence in the present study phytochemical screening of some important medicinal plants was carried out.
Flavonoids belong to a group of polyphenolic compounds, which are classified as flavonols, flavonones, flavones, flavanols, flavan-3-ols and isoflavones according to the positions of the substitutes present on the parent molecule. Flavonoids of different classes have several pharmacological activities.
Foliar epidermal features of 18 species of Euphorbia L. s.l. (Euphorbiaceae) are studied. While the anisocytic and anamocytic stomata are common in herbaceous members (Euphorbia subg. Chamaesyce), the paracytic type is predominant in succulent species (Euphorbia proper).
Background: An ethnobotanical survey was carried out to collect information on the use of medicinal plants in Southern Western Ghats of India (Madurai district, Tamil Nadu). Information presented in this paper was gathered from the paliyar tribes using an integrated approach of botanical collections, group discussions and interviews with questionnaires in the years 1998 – 1999.
