Introduction/Overview
Gypenoside BP2213 (CAS number 862286-45-1), as an important triterpenoid saponin in Gynostemma pentaphyllum, has attracted much attention in recent years due to its multi-target and multi pathway pharmacological activities. Gynostemma pentaphyllum saponins are widely used in traditional Chinese medicine for anti-inflammatory, antioxidant, immune regulation, and anti-tumor purposes. BP2213, as a representative compound, exhibits significant anti lung cancer potential. Lung cancer is one of the malignant tumors with the highest incidence rate and mortality in the world, and its treatment still faces great challenges, especially the poor prognosis of advanced patients. BP2213 intervenes in the proliferation, apoptosis, and signaling pathways of tumor cells by regulating multiple key molecular targets, demonstrating good anti-cancer activity and safety, and has the potential to become a novel anti lung cancer drug.
This article aims to systematically review the chemical structure and physicochemical properties, plant sources and extraction methods, pharmacological activity and mechanism of action, pharmacological evaluation and pharmacokinetic characteristics of Gynostemma pentaphyllum saponin BP2213, and comprehensively analyze the research progress and future development directions of this compound in combination with its application prospects in the treatment of lung cancer.
Chemical structure and physicochemical properties
Gynostemma pentaphyllum saponin BP2213 belongs to the pentacyclic triterpenoid saponin class, with a complex molecular formula and a molecular weight of 955.1450, indicating that it is a natural product with a relatively high molecular weight. Its structural core is a typical pentacyclic triterpenoid skeleton, connecting multiple glycosidic groups, endowing it with high polarity and multifunctional activity. The LogP value of BP2213 is 3.0023, indicating its moderate lipophilicity, which facilitates membrane penetration. However, its extremely high topological polar surface area (TPSA) of 269.82 Å ² reflects strong polarity characteristics, which may limit its oral absorption and bioavailability.
The low water solubility (0.0378 mg/mL) suggests limited solubility in aqueous media, but this can be improved to some extent through formulation processes. The low permeability of the blood-brain barrier means that BP2213 is less likely to enter the central nervous system, reducing the risk of neurological side effects. The hERG channel inhibition experiment showed a negative result, indicating a low risk of cardiac toxicity. The Ames test showed 0.0, indicating no significant mutagenicity and good safety.
In summary, Gynostemma pentaphyllum saponin BP2213 has a complex chemical structure and physicochemical properties. Although it has certain solubility and absorption limitations, its safety indicators are excellent, laying the foundation for subsequent drug development.
Plant sources and extraction methods
Gynostemma pentaphyllum saponins BP2213 mainly come from the gourd family plant Gynostemma pentaphyllum, which is widely distributed in southern China and Southeast Asia. It is traditionally used as a health supplement and traditional Chinese medicine. Gynostemma pentaphyllum contains abundant triterpenoid saponins, and BP2213, as one of the specific saponins, has a relatively low content, making extraction and purification difficult.
Common extraction methods include:
-
Solvent extraction Reflux extraction of dried powder of Gynostemma pentaphyllum using methanol, ethanol, or their aqueous solutions, and dissolution of saponin components using polar solvents.
-
Liquid liquid distribution Separate lipophilic impurities and enrich polar saponin components using organic solvents such as n-hexane and ethyl acetate.
-
Column chromatography separation: Silica gel, C18 reverse phase column and gel filtration column were used for fractionation and purification, and high purity BP2213 was obtained by monitoring with high performance liquid chromatography (HPLC).
-
Optimization of preparation process In recent years, new technologies such as ultrasound assisted extraction and microwave-assisted extraction have been introduced to improve extraction efficiency and purity, and reduce solvent consumption.
Through the above methods, researchers were able to obtain a purity of over 95% of Gynostemma pentaphyllum saponins BP2213, providing a reliable material basis for its pharmacological research.

Its anti-cancer effect is closely related to regulating multiple signaling pathways.
In addition, BP2213 exhibits anti-inflammatory, antioxidant, and immunomodulatory activities, which help improve the tumor microenvironment and enhance the body's immune surveillance and clearance capabilities against tumors. Animal model studies further confirm that BP2213, when administered orally or by injection, can effectively inhibit the growth of lung cancer tumor volume, prolong the survival of experimental animals, and has no significant toxic side effects.
The specific pharmacological activities are summarized as follows:
- Anti lung cancer activity Inhibit tumor cell proliferation, induce apoptosis, and block signaling pathways related to tumor metastasis.
