“…This is a new compound and was not reported by Tuntiwachwuttikul et al (2006) in their paper on P. sarmentosum. The structures of the other eight alkaloids were determined by comparisons of spectral data with that of published data -pellitorine (2) (Rosario et al, 1996) (3) (Schobert et al, 2001), 2,4-tetradecadienoic acid isobutyl amide (4) (Greger et al, 1981), piperine (5) (Parmar et al, 1998), sylvamide (6) (Banerjit et al, 2002), cepharadione A (7) (Akasu et al, 1990), piperolactam D (8) (Sanjay et al, 1974) and paprazine (9) (Ikuo et al, 1991).…”

Detailed chemical studies on the roots of Piper sarmentosum and Piper nigrum have resulted in several alkaloids. The roots of P. sarmentosum gave a new aromatic compound, 1-nitrosoimino-2,4,5-trimethoxybenzene (1). Piper nigrum roots gave pellitorine (2), (E)-1-[3',4'-(methylenedioxy)cinnamoyl]piperidine (3), 2,4-tetradecadienoic acid isobutyl amide (4), piperine (5), sylvamide (6), cepharadione A (7), piperolactam D (8) and paprazine (9). Structural elucidation of these compounds was achieved through NMR and MS techniques. Cytotoxic activity screening of the plant extracts indicated some activity.

“…Decades of investigations in the natural products chemistry of the Piper genus yielded an important amount of monomeric and dimeric alkamides of diverse molecular architectures contributing to their biological activities [20][21][22][23]203,[208][209][210][211][212][213][214][215][216][217][218][219]. Specifically, [4 + 2] dimers were isolated in P. chaba while [2 + 2] dimers were isolated in P. nigrum and P. longum, in both cases together with monomeric amides.…”

ABSTRAKTumbuhan genus Piper mempunyai kandungan minyak atsiri hampir disemua bagiannya, namun komposisi kimianya belum semua dilaporkan. Pada laporan ini kami melakukan isolasi dan identifikasi senyawa kimia minyak atsiri pada bagian buah tumbuhan Piper. Isolasi minyak atsiri buah Piper dilakukan dengan destilasi air menggunakan destilasi Stahl dan analisis komposisi kimia dengan kromatografi gasspektroskopi masa (GC-MS). Kandungan minyak atsiri buah sirih hijau (Piper betle) 1,4% (v/b), cabe jawa (Piper retrofractum) 1% (v/b), dan buah kemukus (Piper cubeba) 1,7% (v/b). Hasil analisis GC-MS menunjukan kandungan utama minyak atsiri adalah senyawa golongan monoterpen, seskuiterpen dan fenil propanoid. Kandungan utama minyak atsiri buah sirih hijau (P. betle) adalah eugenol (12,36%), isokaryofillena (9,55%) dan β-selinena (8,09%), sedangkan komponen utama buah cabe jawa (Piper retrofractum) adalah isokaryofilen (8,88%), β-bisabolen (7,01%) dan zingiberen (6,32%), dan minyak atsiri buah kemukus (Piper cubeba) adalah spathulanol (27,05%), sativen (8,73%) dan germakren D (7,50%).Kata kunci : Piperaceae, Buah, Piper betle, Piper retrofractum, Piper cubeba. ABSTRACTThe Piper genera contains essential oil in all part of the whole plant, but its chemical composition has not been completely reported. In this report we isolated and identified the chemical composition of essential oil from the fruits of Piper. The essential oil of Piper fruits were obtained by Stahl hydrodistilation and analyzed by GC-MS. The oil yielded 1.4% (v/w) of Piper betle, 1% (v/w) of Piper retrofractum, and 1.7% (v/w) of Piper cubeba. The chemical compositions were analyzed by GC-MS showing the presences of monoterpenes, sesquiterpenes, and phenyl propanoids. The major components of P. betle were eugenol (12.36%), isocaryophyllene (9.55%) and β-selinene (8.09%), whereas the Piper retrofractum were isocaryophyllene (8.88%), β-bisabolene (7.01%), and zingiberene (6.32%), and the P. cubeba were spathulanol (27.05%), sativen (8.73%) and germacrene-D (7.50%).
