Plants are a tremendous source for the discovery of new products of medicinal value for drug development.
Today several distinct chemicals derived from plants are important drugs currently used in one or more countries in the world. During the past decade, traditional systems of medicine have become a topic of global importance. Current estimates suggest that, in many developing countries, a large proportion of the population relies heavily on traditional practitioners and medicinal plants to meet primary health care needs.
Although modern medicine may be available in these countries, herbal medicines (phytomedicines) have often maintained popularity for historical and cultural reasons. Concurrently, many people in developed countries have begun to turn to alternative or complementary therapies, including medicinal herbs.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
1. Synonyms
Sarpagandha, Chandrika; Chootachand; Indian snake root.
Biological Source
Rauwolfia consists of dried roots of Rauwolfia serpentina Benth.,
belonging to family Apocynaceae
.
2. Geographical Source
It is also found in India Burma, Thailand, Philippines, Vietnam, Indonesia,
Malaysia, Paki-stan and Java.
In India it occurs in the sub-Himalayan, Assam, especially in Dehradun,
Siwalik range, Rohelkhand, Gorakhpur ascending to 1,300 m, east and west
ghats of Tamil Nadu, in Bihar (Patna and Bhagalpur), Konkan, Karnataka and
Bengal.
3. Cultivation and Collection
Rauwolfia grows in tropical forests at an altitude of 1,200– 1,300 m at temperature
10–40°C. Enough rain or irrigation for its cultivation.
pH 4–6
Propagation is done by planting seeds, root cuttings or stem cuttings.
Roots and rhizomes are dug out in October–November when the plant roots are two
to four years old. The aerial parts and roots are separated.
The roots are washed and dried in air. The roots containing moisture up to 12%
should be protected from light.
Rauwolfia should be packaged and stored in well-closed containers in a cool, dry
place that is secure against insect attack.
4. Morphology
The roots are rarely branched. Rootlets, 0.5–1 mm in diameter.
The outer surface is greyish-yellow, light-brown or brown.
Circular scars of root-lets are present.
The fracture is short.
.
Pieces of rhizome closely resemble the root but may be identified by a small
central pith.
Slight odour is felt in recently dried drug which decreases with age; taste is
bitter.
9. Microscopy description
Transverse section of the root shows a stratified cork, which is divided, into two to
eight alternating zones. It consists of one to seven layers of smaller and radially
narrower, suberised, nonlignified cells alternating with one to three layers of larger
radially broader, lignified cells.
The phelloderm is composed of about ten to twelve layers of tangentially elongated
to isodiametric, cellulosic parenchymatous cells. Cells of secondary cortex are
parenchymatous and contain starch grains, simple and compound (two to four
components), spherical with a distinct hilum in the form of a split.
10. Phloem is narrow and consists of parenchyma with scattered sieve tissue;
parenchyma alternate with broader medullary rays composed of large cells and
usually two to four cells wide.
Xylem is wide, entirely lignified and usually shows two to five annual rings. Medullary
rays, one to five cells wide, contain starch grains and alternate with secondary xylem
consisting of vessels, tracheids, fibres and parenchyma. Xylem vessels have pitted
thickening
11. Chemical Constituents
Rauwolfia contains about 0.7–2.4% total alkaloidal bases from which more than
80 alkaloids have been isolated.
The prominent alkaloids isolated from the drug are reserpine, rescinnamine, ψ-
reserpine, rescidine, raubescine and deserpidine.
The other alkaloidal components are ajmalinine, ajmaline, ajmalicine (8-
yohimbine), serpentine, serpentinine, tetrahydroreserpine, raubasine, reserpinine,
isoajamaline and yohambinine.
14. Isolation of Reserpine
• Roots are powdered & moisten with 10 % NaHCo3 & ext. with benzene untill
give positive reaction with HgI2
• Conc. It & add ether & dil. HCl again conc. It & separate acid layer.
• Again washed with ether. Make it alkaline with NH3 Then ext. with CHCl3
• The CHCl3 ext. washed with 10% Na2CO3 Dry it & purify it by using
methanol.
• Get pure crystal of Reserpine
