Abstract: The increasing global burden of cancer points toward the urgent need for novel, effective and safer therapeutic agents. In this context, sesquiterpenes from the Asteraceae family offer a promising natural reservoir for anticancer drug discovery due to their structural diversity and potent biological activities. The family Asteraceae represents a significant source of structurally diverse sesquiterpenes. This study compiles and reviews sesquiterpenoid compounds reported from various Asteraceae species, highlighting their ethnomedicinal relevance and cytotoxic activities. Data were compiled through an extensive literature survey using scientific databases and carefully selected keywords related to Asteraceae, sesquiterpenes, sesquiterpene lactones and anticancer activity. The collected information was systematically analyzed to identify major compound classes, their plant distribution and associated pharmacological effects. Major constituents such as β-caryophyllene, α-humulene, germacrene D and spathulenol were found to be widely distributed across various species. These compounds are reported to exhibit diverse biological activities, particularly anti-proliferative, anti-inflammatory and neuroprotective effects, which may contribute indirectly to cancer prevention and therapeutic support. Their widespread occurrence across multiple genera also suggests a conserved biosynthetic capacity within the family. This review emphasizes their distribution across plant species, documented cytotoxic and pharmacological effects and their overall relevance as lead compounds in future cancer research and drug development strategies.

Keywords: Anti-proliferation, cancer, ethnomedicine, pharmacology, sesquiterpenes

Introduction

The plant family Asteraceae (Compositae) is one of the largest and most widely distributed families in the plant kingdom, comprising more than 1,600 genera and over 23,000 species (Kacholi, 2026). It is not only ecologically dominant across diverse habitats but also recognized for its ornamental and aesthetic value (Nadaf et al., 2025). Species such as Chrysanthemum indicum, Bidens pilosa, Chromolaena odorata, Eclipta prostrata and Tridax procumbens are widely appreciated for their bright inflorescences and vibrant floral structures. This ornamental richness has significantly contributed to horticulture, landscaping and cultural symbolism across different regions. However, beyond this visible beauty lies deeper biochemical richness, where these visually appealing plants serve as reservoirs of structurally diverse and pharmacologically important secondary metabolites. A key feature of the Asteraceae family is its extraordinary capacity to produce specialized metabolites (Rolnik and Olas, 2021), particularly terpenoids, flavonoids, phenolics and alkaloids, which function as chemical defenses against herbivores, pathogens and environmental stress. Sesquiterpenes and sesquiterpene lactones areimportant compounds found among them, known for their diverse pharmacological properties, including anti-inflammatory, antimicrobial, antioxidant and anticancer activities (Teng et al., 2025). Structurally, sesquiterpenes are C15 terpenoids derived from the mevalonate pathway and their chemical diversity is greatly expanded through oxidation, cyclization and lactonization processes (Cheng et al., 2025), resulting in a broad range of bioactive derivatives.In recent decades, cancer has emerged as one of the leading global health challenges, with steadily increasing incidence and mortality rates worldwide (Siegel et al., 2025). Factors such as population aging, environmental pollution, unhealthy lifestyles and genetic predisposition have contributed to its rapid spread (Wu et al., 2024). Despite significant advances in modern medicine, conventional cancer therapies such as chemotherapy, radiotherapy and targeted drugs often suffer from limitations including severe side effects, low selectivity, drug resistance and high treatment costs (Zafar et al., 2025). These challenges have intensified the search for safer, more effective and naturally derived therapeutic agents. In this context, plant-derived natural products have gained significant attention and sesquiterpenoids, a class of terpenoids stand out as promising anticancer candidates. A wide range of Asteraceae species produce biologically active sesquiterpenes with notable cytotoxic properties (Ivanescu et al., 2015). Common sesquiterpene hydrocarbons such as β-caryophyllene, α-humulene, germacrene D, spathulenol and caryophyllene oxide are widely distributed in species like Sphagneticola calendulacea, Chromolaena odorata, Bidens pilosa, Tridax procumbens and Eclipta prostrata, where they contribute to anti-proliferative and anti-inflammatory effects (Sotto et al., 2020). These compounds are often associated with modulation of signaling pathways involved in tumor progression and cell survival. More importantly, sesquiterpene lactones represent the most potent anticancer subgroup within Asteraceae, characterized by the presence of an electrophilic α-methylene-γ-lactone moiety that enables covalent interaction with cellular nucleophiles (Babaei et al., 2018). For example, compounds such as parthenin, coronopilin, hymenin and ambrosin from Parthenium hysterophorus, a wide spread invasive weed in the Indian subcontinent, demonstrated strong cytotoxic, anti-proliferative and apoptosis-inducing activities against various cancer cell lines (Nagarkar et al., 2025). Interestingly, many of these medicinal plants are also deeply rooted in ethnomedicinal practices, where they are traditionally used for treating wounds, inflammation, skin diseases, fever and infections (Lata and Sharma, 2024). This traditional knowledge strongly correlates with their modern pharmacological validation, suggesting that their therapeutic effects may be attributed to the presence of these bioactive sesquiterpenes. The convergence of traditional usage and scientific evidence reinforces the importance of Asteraceae (Plate 1) as a valuable source for drug discovery. The diversity of sesquiterpenes within this family not only reflects evolutionary adaptation but also provides a rich chemical library for the development of novel anticancer agents (Zhang et al., 2005). Given the increasing global burden of cancer and the limitations of current therapies, this review explores the sesquiterpenoids from selected members of Asteraceae, offering a promising and sustainable pathway for future pharmaceutical research and drug development.

Methodology

The present review was conducted through a comprehensive assessment of available literature concerning the family Asteraceae. Relevant information was collected from major scientific databases, including Google Scholar, Scopus, PubMed, Web of Science and Plants of the World Online (POWO), to obtain updated taxonomic information as well as peer-reviewed articles, review studies, ethnobotanical reports and pharmacological investigations. Specific search terms such as “cancer”, “anti-cancer compounds”, “secondary metabolites”, “sesquiterpenes”, “ethnomedicinal applications” and “proliferation” were employed to identify particular studies. Furthermore, regional floras, books and published reports documenting traditional medicinal knowledge and species distribution were also examined. Only studies providing authentic scientific evidence and validated ethnomedicinal information were considered for inclusion. The collected data were critically evaluated, synthesized and organized into relevant thematic sections to provide a coherent and systematic presentation of the findings. (Kumar, 2025; Sahu et al., 2026).

Anti-cancer sesquiterpenes from the Asteraceae family

The Asteraceae family is a rich source of anti-cancer sesquiterpenes, mainly in the form of sesquiterpene hydrocarbons (e.g., β-caryophyllene, α-humulene, germacrene D) and sesquiterpene lactones (e.g., parthenin, coronopilin, ambrosin, goyazensolide) (Satapathy et al., 2024; Praise et al., 2025). Among them, sesquiterpene lactones show stronger cytotoxic and anti-proliferative activity, often linked to apoptosis induction through reactive lactone groups (Jankovská et al., 2026). In contrast, sesquiterpene hydrocarbons generally exhibit moderate anti-cancer effects and often contribute to anti-inflammatory activity. Ethnomedicinal uses include wound healing, skin treatment

These compounds are widely distributed across genera such as Acmella, Chromolaena, Bidens and Parthenium, indicating their conserved role in plant defense (Bartolome et al., 2013; Kaur et al., 2021), align well with the reported bioactivities (Table 1), supporting traditional knowledge associated with members of Asteraceae and making them an important natural reservoir of bioactive sesquiterpenes with strong potential for anti-cancer drug discovery.
