Qualitative and Quantitative Assessment of Fatty Acids of Buddleja asiatica by GC-MSAli, F., Ali, I., Bibi, H., Malik, A., Stern, Ben, Maitland, Derek J. 03 2013 (has links)
No / To analyze the fatty acid contents of Buddleja asiatica Lour, both the non-volatile oil and fat obtained from the n-hexane soluble sub-fraction were subjected to GC/MS using BSTFA (N,O-bis(trimethylsilyl) trifloroacetamide) derivatization. The oil showed the presence of six fatty acids including palmitic acid (46.75 %), linoleic acid (37.80 %), stearic acid (10.98 %), arachidic acid, margaric acid and lignoceric acid (< 3 %). Analysis of the fat revealed nine fatty acids including lignoceric acid (43.12 %), behenic acid (26.39 %), arachidic acid (9.29 %) and stearic acid (5.3 %). Cerotic acid, montanic acid, melissic acid and palmitic acid were found in low amounts (< 5 %) while trycosylic acid (4.83 %) was the only fatty acid with odd number of carbon atoms. The oil showed a low thermal stability. / Higher Education Commission Pakistan

Buddlejol, a new alpha-chymotrypsin inhibitor from Buddleja asiaticaKhan, F.A., Khan, N.M., Khan, H.U., Khan, S., Ali, N., Ahmad, S., Maitland, Derek J. January 2015 (has links)
No / Buddlejol (1), a new sterol, has been isolated from the ethyl acetate soluble fraction of the antispasmodic plant Buddleja asiatica along with stigmasterol (2), lignoceric acid (3), taraxerol (4) and alpha-amyrin (5), respectively. The structure of Buddlejol (1) was established as (24S)-stigmast-5,22-diene-7 beta-ethoxy-3 beta-ol by spectral analysis and comparison with closely related structures. Buddlejol revealed to be a competitive inhibitor of chymotrypsin with the Ki value of 10.60 A mu M as indicated by Lineweaver-Burk and Dixon plots and their re-plots against its chymotrypsin inhibition assay, while the other compounds showed less inhibitory potential. The bioassay-guided isolation was stimulated by the preliminary cytotoxic screening of various fractions of B. asiatica.
