A new furofuran lignan (1) along with four knowns (2-5) were isolated from the bark of Magnolia kobus. Their structures were elucidated as (+)-2α-(3',4'-dimethoxyphenyl)-6α-(3"-hydroxy-4",5"-dimethoxyphenyl)-3,7-dioxabicyclo[3.3.0]octane (1), (+)-sesamin (2), (+)-yangambin (3), (+)-kobusin (4) and (+)-eudesmin (5) on the basis of their comprehensive spectroscopic analysis including 2D NMR and by comparison of their spectral data with those of related compounds.

A new benzofuran, 5-(3"-propanoyloxypropyl)-7-methoxy-2-(3', 4'-methylenedioxyphenyl)-benzofuran (1) along with four known compounds (2-5) were isolated from the seeds of S. obassia. Their structures were established on the basis of their various spectroscopic analysis including 1D and 2D NMR and by comparison of their spectral data with those of related compounds. Among the known compounds, the 13C NMR data of compound 5 is being reported here for the first time.

The leaves of Indian yew Taxus wallichiana, growing in Gulmarg, Jammu and Kashmir, on hydrodistillation,
gave 0.025% oil on a fresh weight basis. GC and GC-MS analysis of the oil resulted in the identification
of 62 constituents, representing 93.3% of the oil. The main constituents identified in the leaf oil were (E)-2-octen-1-ol
(14.5%), n-pentacosane (8.1%), caryophyllene oxide (7.1%), 1-octanol (6.5%), hexanoic acid (5.5%) and (Z)-3-hexenol
(4.1%).

The essential oil composition of Murraya exotica leaves and flowers from CIMAP Research Farm,
Lucknow, were analysed by GC and GC–MS, which resulted in the identification of 56 and 72 constituents, representing
99.8% and 99.2% of the oils, respectively. The leaf oil showed (E)-nerolidol (27.8%), α-zingiberene (10.0%), β -
caryophyllene (9.7%), (E,E) farnesol (8.9%) and δ -elemene (5.1%) as the major constituents, while the flower oil showed
(E,E,E)-α-springene (23.8%), (E)-nerolidol (18.7%), (E,E) α-farnesene (13.2%), methyl palmitate (6.8%) and germacrene

The essential oil composition of four accessions, C-62, P-17, C-45 and C-59, with control LK of Mentha
× piperita, cultivated at the CIMAP Research Farm, Lucknow, were analysed by GC and GC–MS, which resulted in the
identification of 61, 74, 67, 68 and 55 constituents, representing 99.7%, 99.6%, 99.7%, 92.3% and 91.6% of the oils,
respectively. The performance of accessions C-62, P-17, C-45 and C-59 against the control LK was also evaluated. The
