What is Cryptotanshinone?
Cryptotanshinone (CT) is a bioactive diterpenoid quinone extracted predominantly from Salvia miltiorrhiza (Danshen), a traditional Chinese medicinal herb. Structurally characterized by its phenanthraquinone core, Cryptotanshinone has been of great interest due to its diverse biological activities, including modulation of oxidative stress, cellular signal transduction, and enzyme inhibition. Its lipophilic nature and complex biosynthetic background necessitate high-precision analytical techniques to ensure accurate characterization, quantification, and quality control.

FAQ of Cryptotanshinone Analysis Service
How should I prepare and ship my samples to ensure stability?
For plant tissues or fermentation broths, freeze samples at -80°C or ship on dry ice. Liquid samples can be stabilized with additives like 0.1% formic acid to prevent degradation. Light-sensitive samples should be packed in opaque containers.
What if my Cryptotanshinone concentration is too high or too low for detection?
Our LC-MS/MS method has a broad linear range (0.5–1000 ng/mL). For trace-level samples, we offer optional pre-concentration protocols (discuss during project setup).
Can you help interpret unexpected peaks or unidentified metabolites in my data?
Yes! Raw data files (.raw) are included in deliverables, and our standard report highlights anomalies. For deeper analysis (e.g., unknown metabolite identification), upgrade to our Expert Annotation Service for detailed insights from our metabolomics specialists.
Do you offer discounts for large-scale projects?
Yes! Volume discounts apply for projects with 50+ samples (tiered pricing available).
Can I customize the metabolite panel beyond the listed compounds?
Absolutely. For example, we can integrate cryptotanshinone with phenolic acids (e.g., salvianolic acid B) or other target metabolites.
Will you notify me if contaminants (e.g., microbial toxins) are detected?
Yes. We flag non-target peaks in your report and provide a complimentary Contaminant Screening Summary to help identify potential sample quality issues.
Do you support international sample shipments?
Yes. We accept global shipments and provide guidance on customs documentation, import permits, and temperature-controlled logistics.

Title: Simultaneous determination of danshensu, rosmarinic acid, cryptotanshinone, tanshinone IIA, tanshinone I and dihydrotanshinone I by liquid chromatographic–mass spectrometry and the application to pharmacokinetics in rats

Salvia miltiorrhiza Bunge (Danshen) is widely used in traditional Chinese medicine for cardiovascular and liver-related diseases. Its therapeutic efficacy is mainly attributed to two classes of bioactive compounds: hydrophilic phenolic acids (e.g., danshensu, rosmarinic acid) and lipophilic diterpenoid quinones (e.g., cryptotanshinone, tanshinone IIA). Due to their chemical differences and pharmacological relevance, it is critical to quantify both compound groups simultaneously in biological matrices for pharmacokinetic and quality control purposes. However, previous methods lacked comprehensive, sensitive quantification for both classes in vivo. This study developed and validated an LC–MS/MS method using electrospray ionization in both positive and negative modes for simultaneous quantification of six key constituents in rat plasma after oral administration of Danshen preparations.
Chemicals and Reagents
- Standards: Danshensu (DS), rosmarinic acid (RA), cryptotanshinone (CT), tanshinone I (TI), dihydrotanshinone I (DT), tanshinone IIA (TS), and fenofibrate (internal standard, I.S.).
- Solvents: Acetonitrile, ethyl acetate, glacial acetic acid (HPLC grade), hydrochloric acid.
Animals
- Male rats (specific pathogen free) used for plasma collection and pharmacokinetic studies.
- All procedures followed institutional animal care guidelines.
Sample Preparation
- Liquid–liquid extraction chosen over organic precipitation.
- Optimal condition: Acidification to pH 2.0 with 12% HCl, followed by double extraction with ethyl acetate.
- Supernatants were evaporated and reconstituted before LC–MS/MS analysis.
Chromatographic Conditions
- Column: Capcell Pak MG C18.
- Mobile phase: Gradient elution from acetonitrile–0.5% acetic acid aqueous solution (8:92 to 78:22, v/v).
- Flow rate: 0.2 mL/min.
- Retention times for DS, RA, CT, DT, TI, TS, and I.S. ranged from ~4.35 to 25.26 min.
Mass Spectrometry Conditions
- Ionization: Electrospray ionization (ESI).
- Mode: Negative ion mode for phenolic acids (first 19 min), then switched to positive mode for tanshinones.
- MRM (Multiple Reaction Monitoring) used for quantification.
- Instrumental parameters (temperature, flow rate, fragment energy) optimized for each analyte.
Method Validation
- Parameters evaluated: Selectivity, linearity, LOD/LOQ, precision, accuracy, recovery, and stability.
- Calibration performed over a range of 0.1–2500 ng/mL depending on the analyte.
- Stability assessed under various storage and processing conditions.
Pharmacokinetic Study
- Rats administered single oral dose of danshen extract.
- Plasma samples collected at multiple time points.
- Concentration–time profiles analyzed using a two-compartment model.
A sensitive and selective LC–ESI–MS/MS method was successfully developed and validated for the simultaneous determination of six active compounds (danshensu, rosmarinic acid, cryptotanshinone, tanshinone I, dihydrotanshinone I, and tanshinone IIA) from danshen extracts in rat plasma. Optimal sample preparation involved liquid–liquid extraction at pH 2.0 using ethyl acetate. A Capcell Pak MG C18 column and a gradient elution system (acetonitrile–0.5% acetic acid) enabled efficient separation. Electrospray ionization in time-segmented negative/positive ion modes improved sensitivity for both phenolic acids and tanshinones. The method exhibited good linearity (r² > 0.995), acceptable LOD and LOQ, high extraction recoveries (>60%), and stable performance under various storage and handling conditions. Pharmacokinetic analysis showed all compounds followed a two-compartment open model, with notable differences in absorption, distribution, and elimination. TS was shown to be both a parent compound and a metabolite of CT.
LC–MS/MS chromatograms of: (A) blank rat plasma; (B) blank plasma spiked with six active compounds and I.S.; (C) rat plasma at 1.5 h after oral administration of danshen extract. Panels show total ion current (a) and selected reaction monitoring (SRM) for each analyte: danshensu (b), rosmarinic acid (c), cryptotanshinone (d), dihydrotanshinone I (e), tanshinone I (f), tanshinone IIA (g), and internal standard fenofibrate (h).
Pharmacokinetics profiles of: (A) danshensu and rosmarinic acid; (B) cryptotanshinone, tanshinone I, dihydrotanshinone I and tanshinone IIA in plasma following administration of a single oral dose of danshen extracts to rats.
The developed LC–ESI–MS/MS method is accurate, precise, sensitive, and robust, making it suitable for the simultaneous quantification and pharmacokinetic profiling of key phenolic and diterpenoid compounds in danshen extracts. This study provides a comprehensive pharmacokinetic understanding essential for the clinical and therapeutic evaluation of danshen preparations.
