Abstract
Diterpenoids are widely distributed natural products and have caused considerable interest because of their unique skeletons and antibacterial and antitumor activities and so on. In light of recent discoveries, ent-kaurane diterpenoids, which exhibit a wide variety of biological activities, such as anticancer and anti-inflammatory activities, pose enormous potential to serve as a promising candidate for drug development. Among them, spirolactone-type 6,7-seco-ent-kaurane diterpenoids, with interesting molecular skeleton, complex oxidation patterns, and bond formation, exhibit attractive activities. Furthermore, spirolactone-type diterpenoids have many modifiable sites, which allows for linking to various substituents, suitable for further medicinal study. Hence, some structurally modified derivatives with improved cytotoxicity activities are also achieved. In this review, natural bioactive spirolactone-type diterpenoids and their synthetic derivatives were summarized.

Abstract
Electrospray ionization tandem mass spectrometry (ESI-MS(n)) using an ion trap instrument and accurate mass measurement on a quadrupole time-of-flight (Q-TOF) mass spectrometer has aided the structural characterization and differentiation of the enmein and spiro-lactone types of ent-6,7-seco-kaurane diterpenoids from Isodon species. The mass spectral fragmentation data from both techniques was compared to obtain the mass spectrometric fragmentation pathways of the ent-6,7-seco-kaurane diterpenoids with high confidence. The analysis revealed that losses of CH(2)O and CO(2) are the predominant process for the enmein type of ent-kauranes in negative ion mode, and the loss of CO(2) is typical for the spiro-lactone type in positive ion mode. In addition, compounds of the spiro-lactone type with a conserved core structure but different substituent groups, such as acetyl, hydroxyl, and aldehyde moiety, resulted in diagnostic product ions by means of successive losses of AcOH, H(2)O, and CO, respectively. The fragmentation knowledge will facilitate the analysis and identification of the ent-6,7-seco-kauranes in future plant research.
