“…In addition, H-10 also correlated with the H-7 methylene (δ H 2.13) and H-8 methine (δ H 5.49) of the allyl group. The sign of specific rotation of 1 ([α] D 31.8 = −0.169) was found negative which was opposite to the reported compound ([α] D 24 = + 5.64) [ 24 ]. Its absolute configuration was assigned as 2S.…”

Illicium griffithii Hook. f. & Thoms is an endemic medicinal plant of North East India found in the Eastern Himalayan region of biodiversity mega centre. Herein, chemical investigation of I. griffithii , afforded five compounds and their structures were determined through extensive use of NMR, HRMS, and FT-IR spectroscopy. The complete proton-proton, proton-carbon coupling network of compound 1 was determined using 1 H- 1 H COSY, HSQC and NOESY NMR experiments. All the compounds were evaluated for their cytotoxic activity by MTT assay and antimicrobial activity by Agar well diffusion method. Compound 1 exhibited significant cytotoxicity activity against Lung cancer (A549) and pancreatic cancer (MIAPaCa2) cell lines with IC 50 values of 15.01 ± 2.69 μg/mL and 47.77 ± 2.38 μg/mL, respectively. Further, the compound 1 exhibited good antimicrobial activities against Escherichia coli and Candida albicans with MIC 7.50 ± 0.28 μg/mL and 7.50 ± 0.86 μg/mL, respectively. The other isolated compounds along with the extracts of I. griffithii also displayed moderate anticancer and antimicrobial activities against respective strains. To the best of our knowledge, this is the first study of isolation of compounds from bark, wood, and leaf along with cytotoxicity and antimicrobial activities of I. griffithii from the North Eastern region of India and could be a potential herbal medicine in near future.

Some Miocene‐fossil wood of Pinus griffithii preserved as lignified wood in brown coal was found in an open coalmine in Xundian of Yunnan Province, China. To explore its chemical components, here we show the palaeophytochemical investigation of this Pliocene‐fossil wood of P. armandii, resulting in the isolation of 11 compounds (1–11) including one new compound named 3,3‐dimethoxy‐24‐ethyl‐cholestan (1) by liquid column chromatography. Furthermore, sixteen volatiles were detected from this fossil wood by gas chromatography‐mass spectrometry (GC‐MS). These structures of 11 compounds were elucidated by analysis of their MS, 1D and 2D‐NMR spectra, and comparison with published data.
