Essential oil components in the seed masses of Amomum xanthioides and its related species from Southeast Asia and China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Previously, to develop an objective identification method for Amomi Semen (AS), the nucleotide sequences of nrDNA ITS region and two cpDNA regions of nine Amomum taxa specimens from Southeast Asia and China were determined, and the generated phylogenetic tree showed six taxa specimens were divided into four groups. In this study, 51 crude drug samples of AS in Japanese markets were classified into four groups or species based on their ITS sequences. Approximately 67% of samples were derived from A. villosum var. xanthioides or A. xanthioides, A. villosum var. villosum and A. longiligulare prescribed in Japanese Pharmacopoeia, and the rest were mixed with A. uliginosum and A. microcarpum. Subsequently, the essential oil compositions of Amomum taxa specimens and AS samples were determined by GC-MS to characterize each group or species. Group 1(A. xanthioides) samples were characterized by containing higher amount of camphor(6) than bornyl acetate(9), and a specific germacrene D-4-ol; group 2(Chinese A. villosum var. villosum and var. xanthioides) by containing higher amount of 9 than 6, a specific isobornyl acetate; group 3(Laotian A. villosum var. villosum and A. longiligulare) by containing higher amount of 6 than 9, and a characteristic neointermedeol, except for A. longiligulare specimen from Hainan, China; group 4(A. uliginosum) by containing equivalent amount of 6 and 9, and the specific (E,E)-farnesyl acetate and (E,E)-farnesol. A. microcarpum samples were discriminated from the above groups by absence of 6 and 9, and with higher amount of (E)-nerolidol. There was a good correlation between genetic classification and chemical discrimination.
