Anticancer Screening of Various Seed Extract of Cardiospermum halicacabum on Human Colorectal, Skin and Breast Cancer Cell Lines

Background: In the modern lifestyle, the increase in cancer and related chronic disorders is a major public health problem. In spite of different methods used for the treatment of these conditions, natural medicines have high demands due to their significant effects as immune enhancement and therapeutic agents and fewer side effects in comparison with other treatment methods. Hence, this study was undertaken to evaluate the cytotoxic effect of cardiospermum halicacabum Linn. seeds, based on traditional claims. Methods: A Soxhlet extractor was used to obtain different extracts from seeds of C. halicacabum Linn. Sulforhodamine B colorimetric (SRB) assay used for the evaluation of the cytotoxic effect of the various extracts on HT-29, HCT-15 colon carcinoma, SK-MEL-2 skin carcinoma, and MCF-7 breast carcinoma. The results were compared against Doxorubicin as a standard drug. Results: The results of the present study showed the potent cytotoxic activity of n-hexane extract of seeds of C. halicacabum Linn. against the MCF-7 breast cancer cell line with 50% growth inhibition value (GI50) of 12.8 ?g/ml but other extracts showed poor activity in other tested cell lines. Conclusions: The results indicated the potential medicinal value of C. halicacabum Linn. seeds oil with the highest extractive yield as an antineoplastic agent. However, further studies are needed for the isolation of the active anticancer compounds and evaluating the mechanism of action of the responsible compound

Ethnobotanical Diversity of Trees and Shrubs of Iran: A Comprehensive Review

Iran, possessing unique topographic and diverse climatic conditions, is the home of 8167 vascular plant species. Iran has a historical tradition in using plants for medicinal purposes. Approximately 2075 species over the whole are popularly characterized as medicinal or aromatic. Medicinal trees and shrubs compose a significant percentage of Iranian medicinal flora. Nonetheless, there are no integrated databases on their applications and most of the publications and documents have been scattered to date. Therefore, the present investigation aims to integrate the published literature considering its ethnobotanical aspects that would serve as promising precursors for developing potent medicines of plant origin. In the study, we compile information about ethnobotany of trees and shrubs of Iran. Our survey found 174 taxa belonging to 109 genera and 56 families. The majority of species were classified in Rosaceae, Fabaceae, Rutaceae, Salicaceae, and Lamiaceae families. Rosaceae was the most dominant, representing 21.8% of the total plant species recorded, among them, the genus with the highest number of species was Prunus (16 species). Berberis vulgaris, Citrus limon, and Betula pendula have the highest number of medicinal uses (24 number of uses) in Iran. Leaves (22.7%) represented the most dominant usage of the plant parts, while the most commonly used preparation method was infusion (33.5%). Most of the plant species have been consumed for digestive system treatment (21%), followed by immune system treatment (20%). The present review highlights that different trees and shrubs taxa have great traditional applications in various healing throughout the Iranian territory. The represented data can potentially be a precious reference containing useful information for directing further phytochemical, biological, and pharmacological investigations. Several endemic species of trees and shrubs, particularly Ribes khorasanicum, are frequently used in Iranian traditional medicine. Because of overharvesting, these species are calling a wake-up alarm for conservation
