  • A new aromatic amide, methyl-N-(3-carbamoylpropionyl) anthranilate was isolated for the first time as a natural compound and one known $C_{19}-diterpene\;alkaloid$, avadharidine was also obtained from the root of Aconitum pseudolaeve var. erectum. The\;LD_{50}$ values of water extract and MeOH extract of the root of Aconitum pseudolaeve var. erectum in mice were 1. 23 g (13. 6 g crude drug) and 0. 77 g(5. 13 g crude drug)/kg, p.o., respectively.

  • The diterpene acid 1 was isolated from the roots of Anisotome lyallii(Apiaceae/Umbelliferae). The structure of the compound was elucidated as anisotomenoic acid 1 on the basis of spectroscopic methods. This compound was evaluated against P388 murine leukaemia and B 16/F10 melanoma cells.

  • Objectives: Here we investigated the anti-lipogenic potential of kaurenoic acid (KA), a diterpene derived from Aralia continentalis, in a cellular model of non-alcoholic fatty liver disease. Methods: HepG2 cells were treated with palmitate for 24h to induce intracellular lipid accumulation. To assess the influence of KA on steatotic HepG2 cells, various concentration of KA was co-administered. After palmitate treatment, Intracellular triglyceride content was measured. Expression level of several lipogenic genes, sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), and stearoyl-CoA desaturase-1 (SCD-1) were measured using Western-blot analyses or RT-PCR. Results: Palmitate markedly increased intracellular triglyceride level and expression of related lipogenic genes in HepG2 cells, and which was relieved by co-administered KA. Conclusions: It is conceivable that that KA may have a pharmacological potential to reduce lipid accumulation in non-alcoholic fatty liver disease.
