Science has always moved forward because of people who dared to question, explore, and create. Among those extraordinary minds stands Dr. Asima Chatterjee, one of India’s most brilliant chemists and an inspiration for generations of scientists. She was a woman far ahead of her time—working in laboratories when women were rarely seen in higher education, leading complex research projects, and producing discoveries that saved lives. Her work in organic chemistry, medicinal plants, anti-malarial drugs, and anti-epileptic research earned her respect across the world.
Early Life: A Child with a Scientific Curiosity
Asima Chatterjee was born on 23 September 1917 in Kolkata (then Calcutta), into a progressive middle-class family. Her father, a lover of botany, often collected plants and talked about their medicinal value. This environment created a natural curiosity in young Asima. While many children played outside, she was deeply fascinated by how plants could heal the human body.
She grew up during a time when the idea of educating girls at higher levels was uncommon. Yet her family believed in empowering daughters with education. This support gave Asima the confidence to dream big and follow her passion for science.
Academic Journey: Breaking Barriers in Higher Education
Asima Chatterjee joined Scottish Church College, one of the best institutions in Kolkata. She was drawn to chemistry—a subject dominated by men. Instead of being discouraged, she saw it as a challenge worth accepting.
Her exceptional talent soon became visible. She completed her undergraduate and postgraduate studies with distinction. In 1944, she achieved a historic milestone:
She became the first woman in India to earn a Doctor of Science (DSc) degree in chemistry.
Her research focused on natural products—chemical compounds found in plants. This field later became the foundation of her groundbreaking medical discoveries.
Early Research Interests: The World of Medicinal Plants
India has a long tradition of using herbs for healing. Asima Chatterjee’s early work explored how these plants worked at a chemical level. She believed that India’s forests and biodiversity held secrets that modern science could decode.
Her research included:
-
Alkaloids – chemical compounds found in plants known for their medicinal effects
-
Glycosides – plant compounds with potential therapeutic benefits
-
Terpenoids – substances widely used in drug development
She studied plants like Catharanthus roseus, Solanum trilobatum, and Alstonia scholaris, identifying their active chemical compounds. This expertise became extremely valuable when the world was battling diseases such as malaria and epilepsy.
Scientific Breakthrough: Developing Anti-Malarial Drugs
One of Asima Chatterjee’s greatest contributions to global health is her work on anti-malarial drugs. In the mid-20th century, malaria was one of the world’s most dangerous diseases, killing millions each year. India, too, suffered large-scale outbreaks.
Asima Chatterjee wanted to find a solution using India’s natural resources. She began studying plants known in folk medicine to help with fever and infection.
Her most famous achievement was the development of the anti-malarial drug "Ayush-64".
This drug was formulated from medicinal plants such as Alstonia scholaris, which were known in traditional Indian medicine. What made her contribution special was:
-
It used plant-derived chemical compounds, making it safe and accessible
-
It was effective against Plasmodium, the malaria-causing parasite
-
It supported India’s health system when modern drugs were scarce
Her anti-malarial research placed her on the global map and influenced future studies in natural product chemistry.
Contribution to Anti-Epileptic Drugs
Epilepsy, a neurological condition characterized by repeated seizures, was another area where Dr. Chatterjee made significant contributions. She developed anti-epileptic formulations extracted from plant sources. These medicines brought relief to many patients at a time when treatment options were limited.
Her work helped pave the way for alternative and safer anti-seizure medications. It also encouraged scientists to explore natural sources as potential solutions for neurological disorders.
Organic Chemistry and Natural Product Research
Dr. Asima Chatterjee was not just a medicinal chemist; she was a pioneer in organic chemistry, especially in studying compounds from plants. Her expertise helped decode:
-
The chemical structure of alkaloids
-
The behavior of plant-derived molecules
-
How natural compounds interact with the human body
Over her long career, she published more than 400 research papers in national and international journals. Her contributions spanned fields such as:
-
Synthetic chemistry
-
Natural product isolation
-
Spectroscopic analysis
-
Structural chemistry
She worked tirelessly to bring Indian chemistry to international standards.
Leadership and Academic Contributions
Asima Chatterjee spent most of her academic life at the University of Calcutta. She became the first woman to be appointed to the position of Khaira Professor of Chemistry at the university. She also played an important role in developing the university’s chemistry department and inspiring thousands of students.
Her leadership roles included:
-
Serving as Dean of the Science Faculty
-
Guiding several PhD scholars
-
Lecturing across India and abroad
-
Representing India at international scientific conferences
She believed strongly in education as a tool for empowerment and encouraged more women to pursue careers in science.
National Recognition and Awards
Her groundbreaking research earned her numerous prestigious awards. Some of the most important ones include:
Padma Bhushan (1975)
One of India’s highest civilian awards, given for distinguished service in science and engineering.
First Female General President of the Indian Science Congress (1975)
This was a historic achievement that opened doors for many women in Indian science.
Shanti Swarup Bhatnagar Medal
A highly respected award in the field of science and technology.
Honorary DSc degrees from multiple universities
These awards recognized her lifelong contribution to natural product chemistry and medicinal research.
She also became a nominated member of the Rajya Sabha (1982–1990), where she worked to promote science education and research in India.
Challenges She Faced as a Woman Scientist
The journey of Asima Chatterjee was far from easy. She lived in a time when women were often discouraged from pursuing higher education or scientific research. Many laboratories did not permit women to work late hours. Funding for her projects was difficult to arrange. She faced biases and stereotypes, yet she never gave up.
She balanced her scientific career with family responsibilities, proving that with determination and hard work, women can excel in any field.
Her resilience remains a powerful message for girls and women aspiring to choose careers in science and research.
Impact on Global Scientific Community
Asima Chatterjee’s work did not just remain within India’s borders. Her discoveries were studied and used by researchers across the world. Her methods of extracting and isolating natural compounds were adopted globally. Her anti-malarial and anti-epileptic formulations influenced international drug development research.
She placed Indian organic chemistry and natural product research on the world map. Her legacy continues to inspire scientific studies in:
-
