Camptothecin Introduction

Camptothecin (CPT) is an alkaloid isolated from the the bark and stem wood of the Chinese tree, Camptotheca acuminate. CPT showed remarkable anticancer activity in preliminary clinical trials but also severe side effects, which limits its usefulness in patients. Currently, two semi-synthetic derivatives of camptothecin, topotecan and irinotecan, which retain anti-cancer activity but with less severe side effects, are used to treat a variety of cancers.

Where are Camptothecin extracted from?

Xi shu (botanical name Camptotheca acuminata) belongs to the Nyssaceae family and is a huge tree growing up to a height of 25 meters having thin reddish-brown bark and a small number of branches close to its apex. This tree produces shiny green, leathery leaves, while the small, white flowers have curved heads.

Camptothecin Manufacturers And Laboratory Shows

Camptothecin factory

With an investment of 80 million RMB, the construction of the factory started from 2012 and was finished at 2014. There are three production lines that meet the GMP standard in our factory which can process 6,000 ton raw materials each year with production of 900 ton plant extract. Our factory has been issued with the GMP certificate by China Food and Drug Administration in the year 2014.

Camptothecin manufacturer GMP Production Line

Plant extract testing laboratory

Due to the complexity of plant extract and the deficiency industrial standards, one of our founders established a professional testing lab with an investment of 15 million RMB in 2014. The laboratory is equipped with five High performance liquid chromatography, one Gas Chromatograph, one Atomic Absorption Spectrometer, one Liquid mass spectrometry, one TLC scanner, one Automatic polarimeter, one Infrared Spectrometer, one Automatic melting point apparatus, one Mold incubator, one UV-visible spectrophotometer, one Portable Pressure Steam Sterilizer, one Single clean bench, one Explorer quasi-microbalance, one Electronic balance, and one Experimental resistance furnace.

Our Mission And Philosophy

Where to buy Camptothecin? Where to find good Camptothecin Manufacturers and Camptothecin suppliers? Where can i buy Camptothecin? Where can i find Camptothecin price and where to get Camptothecin for sale? Is that the very question that lingers in your mind every time you do purchasing? Well, that should not be your headache any longer since we are committed to help you get rid of it completely. We can provide you with the safest and most effective Camptothecin. To ensure the quality of any products that you buy on your platform, we have signed an investment and cooperation agreement with Natural Medicine Public Technical Service Platform, the largest and most professional third-party testing agency in China. Any extract you buy will have to pass the test of our strategic partner before delivery.
To ensure that the production process is under our control, we have built factory of our own, what’s more, we have bought the most shares of several high-quality manufacturers. From raw material selection, to every specific production procedure, to the storage of every kind of product, every detail is under the inspection of our specialists with at least ten years’ experience.
